Unit 1: The Pattern Envelope

What the Envelope Front Is Telling You

A commercial pattern envelope is a small, dense document. Nearly every square inch of it carries information you will need, and the front is where you decide whether this pattern belongs in your basket at all. Learn to read it deliberately, standing at the rack, before you spend money and an afternoon.

The Picture Is a Proposal, Not a Guarantee

The front shows the finished garment, drawn as a fashion illustration or photographed on a model. Both are honest as far as they go, and both flatter. Illustrations stretch the figure taller and narrower than any of us are, and photographs are styled, pinned at the back, and shot in fabric chosen to hang beautifully. What you are being shown is the design, not the outcome. Your outcome depends on your fabric and your body.

So look past the styling and read the shape. Where does the shoulder seam sit? Is the waist seam at the natural waist or dropped? Is that fullness coming from gathers, from pleats, or from a flared cut? Does the skirt hang straight or swing? Those questions are answered better by the small line drawings than by the glamour picture. Most envelopes print flat technical drawings of every view, usually on the back, sometimes tucked into a corner of the front. The line drawings show seams, darts, pockets, and closures with no shading and no model. They tell the truth about construction. Get in the habit of judging a pattern by the line drawing and using the front picture only for the mood of the thing.

Views Are Separate Garments in One Envelope

A single pattern usually contains several versions of the design, labeled View A, View B, View C, and so on. The views may differ in sleeve length, neckline, hem length, collar, or trim. This matters more than beginners expect, because every other number on the envelope is organized by view. Yardage is listed per view. Notions are listed per view. Cutting layouts are drawn per view. If you choose View B, you follow the B row and the B layout and ignore the rest.

Decide your view before you leave the store, and write the letter on the envelope flap in pencil. Buying fabric for the wrong view is one of the easiest and most expensive mistakes in sewing.

The Identifying Marks

Three pieces of identification sit on the front. The company name tells you whose sizing and whose drafting conventions you are working with; companies differ, and a size 14 from one house is not automatically a size 14 from another. The pattern number is how you find the envelope again in a drawer or a catalog. The size or size range is printed plainly, and it refers to body measurements, not to the size on the tag of the shirt you are wearing. Many modern patterns are printed as multi-size, with several nested sizes on the same tissue, which is a gift when your bust and hip fall in different columns.

Envelopes also carry a fabric suggestion line, often on the back but sometimes echoed on the front. Take it seriously. A pattern drafted for a soft rayon challis will hang like a tent in quilting cotton, and the fault will not be your sewing.

A Pattern Is Something You Are Given

There is an old dignity in working from a pattern. Moses was not asked to invent the tabernacle furnishings out of his own imagination; he was told to make them after the pattern he had been shown. The gift he was given was a plan, and the obedience asked of him was careful attention to it. That is a fair description of what you are doing at the cutting table. Someone drafted this garment, tested it, graded it across a range of sizes, and printed the result on tissue. Your part is to read what you have been given, honestly and slowly, and to make it after that pattern. Restlessness with the plan is what produces a crooked hem.

Three Checks Before You Buy

First, read the line drawing of the view you want and be sure you like the seaming, not just the photograph. Second, check that your body measurements fall inside the printed size range; if your hip measurement is beyond the top of the range, this envelope is the wrong one no matter how much you like it. Third, read the suggested fabrics and be certain you can find one, at a price you will actually pay, in your town or from a source you trust. A pattern you cannot fabric is a pattern you will not sew.

The Back of the Envelope: Where the Real Work Is

Turn the envelope over. The front sold you the garment; the back tells you what it will cost you in fabric, money, and effort. Everything printed here is arranged in a standard order, and once you know that order you can read any envelope from any company in about ninety seconds.

The Four Blocks

The back is built from four blocks of information, usually in this sequence.

The size chart comes first: a grid of body measurements, normally bust, waist, and hip, with a pattern size printed above each column. These are body measurements taken over undergarments, not the measurements of the finished garment, and not the size of clothing you buy in a store.

The yardage table is the largest block, and the most crowded. It is a grid: views run down the left side, sizes run across the top, and the numbers in the cells are yards of fabric. Most tables are split into sections for 45-inch wide fabric and 60-inch wide fabric, because how much you need depends on how wide the bolt is. Separate rows often appear for lining, interfacing, and for fabrics with nap.

The notions list names everything you must buy besides the fashion fabric and thread: buttons and their diameter, a zipper and its length, elastic and its width, hooks, interfacing, bias tape, snaps. This list is written per view.

The description and finished measurements block is a short paragraph of prose describing the garment, followed by finished garment measurements such as finished bust, finished back length from the base of the neck, and finished skirt length. Envelopes also often print these finished numbers directly on the tissue pieces.

Reading It in Order

Work the back in a fixed sequence and you will not skip anything. Find your size from the size chart first, using your own tape measure numbers. Circle that column lightly in pencil. Then find your view. Then read down the yardage table to the intersection of your view, your size, and the bolt width you intend to buy, and write that number down. Then read the notions list for your view and write those items on the same slip of paper. Finally read the finished measurements, which tell you how much ease the designer put in, and decide whether that is the amount of room you want.

Doing it in that order takes a few minutes and prevents the classic store failure, which is standing at the cutting counter with fabric already unrolled while you try to remember whether you needed two and a half yards or three and a quarter.

The Fabric Suggestion Line

Somewhere on the back, usually just under the description, is a line of suggested fabrics: for example, challis, crepe, lightweight linen, or shirting. This is drafting information disguised as shopping advice. The designer drafted the amount of fullness, the sharpness of the curves, and the size of the ease around a fabric of a particular weight and drape. Choose from the list, or choose something with a similar hand, and the garment will behave the way the picture promised. Choose a fabric far stiffer or far heavier and the same tissue will produce a different garment. There is also usually a line reading something like "unsuitable for obvious diagonals" or "not suitable for stripes or plaids," which is a warning that the seam lines will not permit matching.

A Prudent Heart Gets Knowledge

Scripture is not sentimental about diligence. The prudent heart gets knowledge; the wise ear seeks it. Both verbs are active. Nobody absorbs the back of a pattern envelope by holding it hopefully. You read it, you write things down, you go back and check the second column because you were not sure. Sewing rewards that habit in a very plain way, because most of the sorrow in home sewing comes not from clumsy hands but from a number that was never looked up. The five minutes you spend on the back of the envelope is the cheapest work in the whole project.

Keep the Envelope

Do not throw the envelope away when you open it, and do not let it become a rag. It is the only copy you have of the yardage, the notions, and the finished measurements. Slit the flap carefully rather than tearing the end open, and when the project is finished, fold the tissue small enough to slide back in. Many sewers store the envelope in a clear zip bag with the tissue, because tissue refolded after cutting is bulkier than it was new and will split the envelope seams if forced.

Choosing Your Size by the Tape, Not by the Store Label

This is where more first garments go wrong than anywhere else. A woman who buys a size 6 at the mall picks up a size 6 pattern, cuts it, and finds she cannot get it over her shoulders. Nothing was wrong with her sewing. She used the wrong number, because pattern sizing and retail sizing are two different systems that happen to use the same digits.

Retail Sizes Drift; Pattern Sizes Do Not

Store sizing is a marketing decision and it changes. Pattern company sizing is tied to a published table of body measurements printed on every envelope, and those tables have stayed remarkably stable for decades. The practical result is that your pattern size is normally several sizes larger than your retail size, sometimes dramatically so. This surprises people and occasionally stings. Let it go. The number on the tissue is a coordinate, not a verdict, and no one will ever see it. What people will see is a garment that fits across the back.

Taking the Three Measurements

You need three numbers, and you need someone else's hands if you can get them, because measuring yourself pulls the tape crooked.

Bust. Wear the undergarments you intend to wear with the finished garment. Run the tape around the fullest part of the bust and straight across the back, level with the floor. Keep the tape snug enough that it will not slide down, loose enough that you can slip a finger under it. Breathe normally; do not hold your breath or lift your arms.

Waist. Not where a low-rise waistband sits, but the natural waist, which is the narrowest place in your torso and usually about an inch above the navel. Tie a length of narrow elastic around your middle and let it settle while you bend side to side; it will find the natural waist on its own. Measure there.

Hip. The fullest part of the hip and seat, generally seven to nine inches below the natural waist. Stand with your feet together and check in a mirror that the tape is level all the way around; the back is where it slips.

Write all three down with the date. Bodies change, and a measurement sheet from two years ago is a rumor, not a fact.

Reading the Chart

Compare your numbers to the envelope size chart. If all three fall in one column, you have an easy decision. Most of us do not. When your measurements land in different columns, the general rule for a top, dress, or jacket is to choose by the measurement of the area that is hardest to alter. For garments above the waist, that is usually the upper body: shoulders and chest govern fit, and width can be added or taken out at the side seams and waist far more easily than a shoulder can be rebuilt. For a skirt or pants, choose by the hip and adjust the waist.

The measurements between sizes are a legitimate answer too. If you are between columns, the choice depends on the garment: a fitted, structured bodice is usually cut in the larger size and trimmed down; a loose, easy garment can go smaller.

Buying Once, Cutting Twice

There is a habit that pays for itself forever: cut a test garment out of cheap fabric before cutting the good cloth. Muslin, an outgrown bedsheet, or discounted broadcloth is enough. Sew only the major seams with a long basting stitch, around 4 mm, try it on, and see what the tissue actually does to your body. Sewers have called this a muslin or a toile for generations. It is not a detour from the work; it is the work.

Looking Well to Your Going

"The simple believeth every word: but the prudent man looketh well to his going." Believing every word, in this trade, means believing the number on the tag of your jeans, believing the picture on the envelope, believing your recollection of what you measured last spring. Looking well to your going means putting the tape around yourself again this morning and writing down what it actually says. There is real humility in that, and real freedom too. When you sew for your own body as it is, rather than the body of the number you wish you wore, you get clothing that fits, and clothing that fits is comfortable, modest, and quietly dignified in a way that no store size can supply.

When It Still Does Not Fit

If the test garment binds across the upper back but hangs loose at the bust, you have chosen a size that is too large in the cup and too small in the frame; that is a fitting adjustment, not a sizing error, and it is solved with pattern alterations rather than by jumping a size. If everything is uniformly too tight or too loose, the size choice itself was wrong. Change one thing at a time and write down what you changed.

Ease: The Room the Designer Built In

Two sets of numbers appear on a pattern envelope, and confusing them is the second great sizing mistake after using a store size. The size chart lists your body. The finished garment measurements list the garment. The difference between the two is called ease, and understanding it is what turns a sewer who guesses into a sewer who predicts.

Two Kinds of Ease

Wearing ease is the minimum extra room a body needs to move, breathe, sit, and raise an arm. Without it a woven garment cannot be worn at all. It is not a style choice; it is mechanical.

Design ease is everything beyond that: the fullness the designer added to make a shirt blouson, a coat generous over a sweater, a dress soft rather than fitted. Design ease is the difference between two patterns for the same body that look nothing alike.

So a finished bust of 41 inches on a pattern whose size chart lists a 38-inch bust means three inches of total ease. Whether three inches is right depends entirely on what the garment is. A close-fitting woven bodice may carry two to three inches. A relaxed shirt may carry five or six. A winter coat may carry eight or more, because it must go over other clothes. None of these numbers is a rule; they are a way of reading what the pattern intends.

How to Use Finished Measurements

Take a garment you already own and like, one made of a woven fabric similar to what you plan to use. Lay it flat, smooth it without stretching, and measure across the chest from side seam to side seam at the deepest part of the armhole. Double that number and you have its finished bust measurement. Now compare it to the finished bust printed on the pattern envelope or on the tissue itself. If your favorite blouse finishes at 42 inches and the pattern finishes at 39, you already know the pattern will feel tight to you, before you have cut anything.

Do the same for hip on a skirt and for the finished back length from the base of the neck, which tells you where the waist seam or the hem will actually land on you. Comparing garment to garment is faster and far more reliable than imagining.

Knits Are a Different Conversation

Patterns drafted for knit fabrics may carry no ease at all, and some carry negative ease, meaning the finished garment measures smaller than the body it is meant to fit. That is deliberate; the fabric stretches to fill it and hugs the shape. If you cut a negative-ease knit pattern out of a woven fabric, it will not go on. If you cut a woven pattern out of a knit, it will hang shapelessly. Read the envelope line that names the fabric type before anything else.

Where Ease and Modesty Meet

Ease is not only about comfort; it is about coverage. A bodice with almost no ease is a bodice that gaps at the button placket when you reach, rides up when you lift a child, and strains at the bust when you sit down at the table. Adding an inch or two of ease at the fullest point is often the whole solution, and it costs nothing but a wider side seam.

Scripture asks women to adorn themselves in modest apparel, with sobriety, and says that what truly becomes women professing godliness is good works. That is a warm instruction, not a scolding one. It puts clothing in its right and modest place: something to be made well and worn without fuss, so that a life is what people notice. A sewer has an advantage here that a shopper does not. You are not stuck with what a store decided to sell this season. You can lengthen a sleeve, raise a neckline an inch, add ease across the chest, or line a thin fabric, and the garment will still be handsome. Kindly made clothing that covers well and moves easily is a genuine gift to your household, and no one has to be lectured about it.

Fixing Ease Problems

If a test garment is uncomfortably snug everywhere, add ease evenly by cutting the next size up rather than by letting out the seams, which robs you of seam allowance and moves the armholes. If it is snug in one place only, that is a fitting adjustment at that place. If it is baggy and shapeless, you have too much design ease for your taste; take it out at the side seams and, if the shoulders drop past your shoulder point, at the shoulder seam as well.

Write your ease preferences down as you learn them. After three or four projects you will know that you want about four inches at the bust in a shirt and two at the hip in a skirt, and from then on you will be able to read a pattern envelope and know how the garment will feel before you thread the machine.

The Yardage Table and the Width of the Bolt

The yardage table is the most useful grid in home sewing and the one most often misread at the cutting counter. Its logic is simple once you see it: the pattern company laid out every piece on paper for every combination of view, size, and fabric width, measured how long the resulting layout was, added a small margin, and printed the answer.

Why There Are Two Columns

Garment fabric is sold from bolts of standard widths. Quilting cottons and many apparel cottons come 45 inches wide; most suiting, knits, and wide apparel fabrics come 60 inches wide. Wider fabric lets pieces sit side by side instead of end to end, so you need fewer yards of length. That is why the table gives a separate number for each width.

The relationship is not a simple ratio. You cannot take the 45-inch figure, multiply by 45/60, and trust the result, because pattern pieces are rigid shapes that either fit beside each other or do not. A wide skirt panel that measures 32 inches across will nest two-across on 60-inch fabric and not at all on 45-inch, saving you a great deal; a narrow bodice piece may save you nothing. Always read the printed number for the width you are actually buying.

If your fabric is some other width, 54 inches for example, use the number for the next width down and accept the leftover. Buying to the narrower figure is cheap insurance.

The Rows You Might Miss

Beneath the main body of the table there are usually additional rows, and skipping them is a common way to come home short.

Nap. A separate set of numbers appears for fabric with nap, one-way design, or shading. Corduroy, velveteen, and chenille have a surface that catches light differently depending on direction; a print with an obvious top and bottom behaves the same way. All pieces must be laid facing the same direction, which forbids the space-saving trick of turning a piece upside down to nest it. Nap layouts therefore need more fabric, sometimes a half yard more or more than that.

Interfacing and lining. These have their own rows and their own widths, since interfacing is often sold in a narrower width than fashion fabric.

Trim yardage. Bias binding, piping, or ruffles may be listed separately, and self-fabric ruffles come out of your main yardage, not out of thin air.

Buy for the Real World

Add to the printed figure when circumstances warrant. Preshrinking a washable natural fiber will take some length; a quarter yard on a short project and a half yard on a long one covers most shrinkage. Matching a plaid, a stripe, or a large-repeat print costs extra length because you must slide pieces along the fabric until the repeat lines up, and a large repeat can add a yard. If your fabric is a remnant or a one-time find, buy more than you need; you cannot go back for it.

Do not round the printed figure down to the nearest half yard. Cutting counters cut in eighths.

Counting the Cost

The Lord's question about the man who intends to build a tower is a question about arithmetic done in advance. Sit down first and count, He says, whether you have enough to finish. That is not timidity; it is respect for the work and for what the work costs. A sewer who counts the cost before she cuts keeps her money, her fabric, and her peace. A sewer who does not will meet the tower half built: two beautiful sleeves and no cuffs, a bodice cut and nothing left for the facings.

Counting the cost is also honest about time. A view with a lined jacket and bound buttonholes is not a Saturday. Read the notions list and the number of pattern pieces and be truthful with yourself about the season of life you are in.

Working the Table

Put your finger on your view row. Slide across to your size column, inside the block for your fabric width. Read the number aloud. Then check whether a nap row applies to the fabric in your hand, and if it does, use that number instead. Add for preshrinking, add for matching a repeat, and write the total on your list along with the width you are buying. At the counter, ask for that number in yards and inches; there is no shame in reading it off a slip of paper. Everyone who sews well does.

The Notions List: Everything That Is Not Fabric or Thread

Notions is the trade word for the supplies a garment needs besides the fashion fabric and the thread: buttons, zippers, elastic, hooks, snaps, interfacing, bias tape, boning, cord, and specialty closures. The list is printed on the envelope back, arranged by view, and it is short enough to be ignored and expensive enough to be worth reading twice.

Read It Before You Leave the Store

The single most useful habit here is buying notions in the same trip as the fabric. Two reasons. First, color matching is done in the light and against the actual cloth; a zipper tape that looked navy at home will look purple against your fabric under store fluorescents, and a button that seemed neutral will read pink. Take the fabric to the button wall and hold it up. Second, a missing zipper stops the project cold at exactly the point where enthusiasm is highest.

Buy thread at the same time, and buy a shade slightly darker than the fabric rather than lighter. Thread reads lighter once it is stitched into a seam, and a hair darker disappears while a hair lighter shows as a line.

The Numbers That Must Match

Several notions carry a specification, and the specification is not a suggestion.

Zipper length. The list will say something like a 22-inch zipper or a 7-inch zipper. That length is drafted into the seam and into the placement dots on the tissue. A zipper an inch too long will not close at the top of the opening; one too short leaves the seam gaping.

Button diameter. Buttons are commonly listed by size, and the buttonhole markings on the tissue were drawn for that diameter. A larger button will not pass through a buttonhole cut for a smaller one, and if you increase the buttonhole you will have to redraw the spacing so the placket still closes squarely.

Elastic width. A casing is drafted to a stated width, usually a quarter inch wider than the elastic so it will feed through. Three-quarter-inch elastic will not go into a casing built for half-inch elastic, and half-inch elastic in a wide casing will roll and twist.

Interfacing. The list names an amount and often a type: fusible or sew-in, woven or nonwoven, light or medium weight. Weight matters more than brand. Interfacing should support the fashion fabric without stiffening it into cardboard; when in doubt, choose one weight lighter than you think and test a fused sample on a scrap first. Fusibles need heat, moisture, and steady pressure for the time the manufacturer states, and they need the iron lifted and set down rather than slid, because sliding shifts the resin and creates bubbles.

Keep a hand on the iron habit generally: set it on its heel, keep the cord clear of the table edge, and never leave a hot iron in a room where a small child is loose.

Substituting Sensibly

You may substitute freely on appearance and rarely on function. A different color, a different button material, a decorative rather than plain snap — all fine. But do not substitute a lightweight nonwoven where a woven interfacing was called for in a tailored collar, do not put a lightweight polyester zipper in a heavy denim seam, and do not replace elastic with a drawstring in a casing that was drafted with no opening for one.

A Nail in a Sure Place

Isaiah speaks of a servant fastened as a nail in a sure place, and the whole weight of a household hanging on him. It is a homely image, and any sewer knows it in her hands. A garment hangs on its fastenings. The prettiest dress in the world is a failure if the zipper pulls out of a seam sewn in fabric too light to hold it, or if the button on a coat front is set with two passes of thread and no shank. Fastenings are where a garment is either sure or not sure. It is worth doing them slowly, with interfacing behind them, and with the thread doubled where the strain will be. Faithfulness in small structural things is not glamorous work, and it is the work everything else depends on.

Making a Notions List You Can Use

Copy the notions for your view onto a slip of paper, with the numbers: zipper length in inches, button diameter and quantity, elastic width and length, interfacing amount and weight. Add thread. Add anything you know you are out of, such as machine needles in the right size for your fabric. Keep the slip in the envelope when you get home, and check items off as you buy them. A project that stalls for want of a fifty-cent notion is a project that often does not restart.

Opening the Envelope: Tissue, Piece Numbers, and the Guide Sheet

Two things come out of the envelope: a folded block of printed tissue and a large sheet of instructions, usually called the guide sheet. Handle both once, carefully, at a clear table, and the rest of the project goes easier.

Getting the Tissue Out Without Tearing It

Pattern tissue is thin, semi-transparent, and printed on a lightweight paper that takes a crease well and tears in a straight line the moment it is snagged. Slit the envelope flap rather than ripping the end, and pull the contents straight out rather than shaking them. Unfold the tissue on a table, not on your lap, and open it flat before you begin looking for anything.

The tissue arrives as one or more large printed sheets with all the pieces nested together. You will cut the pieces apart, but not yet. First identify what is there.

How a Piece Identifies Itself

Every printed piece carries its own identification, usually inside an outline near the middle of the piece. It gives the pattern number, a piece number or letter, and a plain-language name such as Front Bodice, Back Skirt, Sleeve, or Front Facing. It also states how many to cut and out of what: "Cut 2," "Cut 1 on fold," "Cut 2 of interfacing." On a multi-size pattern the piece is printed with several nested outlines, each with its own line style, and a key on the guide sheet or on the tissue itself tells you which line style belongs to which size.

Read every piece's name before cutting anything. It takes five minutes and it is how you discover that this view uses pieces 1, 2, 5, 6, and 9, and that pieces 3, 4, 7, and 8 belong to a view you are not making.

The Guide Sheet Has Five Parts

Guide sheets from the major companies follow a predictable structure, and knowing the structure lets you find what you need without reading the whole thing.

1. A glossary of symbols and terms. Every mark used on the tissue is drawn and named here: grainline arrows, fold brackets, notches, dots and squares, buttonhole marks, adjustment lines. Sewing terms used in the directions, such as understitch, staystitch, or clip, are usually defined here too.
2. Cutting layouts. A separate small diagram for every combination of view, size group, and fabric width, plus separate diagrams for napped fabrics, for lining, and for interfacing.
3. Interfacing and lining information. Which pieces get interfaced, and how the lining differs from the fashion fabric pieces.
4. Assembly diagrams. Small line drawings, numbered in order, showing what is being joined to what, which side is the right side and which the wrong, and where the stitching goes.
5. Written directions. Numbered sewing steps corresponding to the diagrams.

Read the Whole Thing Before You Sew a Stitch

Sit down with the guide sheet and read the directions for your view straight through, following along in the diagrams, before you cut fabric. You are looking for two things: any step that uses a technique you have not done before, and any step whose order surprises you. Construction sequence is not arbitrary. Facings are attached before side seams in some designs and after in others, and a collar goes in at a particular point because after that point you can no longer reach the seam. If you improvise the order you will meet a step you cannot physically perform.

Highlight the layout diagram you are going to use and cross out the ones you are not. Circle your size in the layout key. This single habit prevents the most demoralizing error in sewing, which is cutting to the wrong layout.

Cloths of Service

Exodus tells us that of the blue and purple and scarlet they made cloths of service, and made the holy garments for Aaron, as the LORD commanded Moses. Two things sit side by side in that sentence: real materials, named by color, and real obedience to a given order. The craftsmen were not less skilled for following instructions; they were skilled in following them. There is no piety in ignoring a guide sheet, and no drudgery in reading one. Ordinary garments made for ordinary people are cloths of service too — clothes to work in, to keep a child warm, to wear to worship. Doing that work in the order it was given to you is a small and genuine faithfulness.

Storing What You Are Not Using

Set aside the tissue pieces belonging to views you are not making; do not cut them out. Fold them and keep them, because a pattern you like will be sewn again in another view. Keep the guide sheet with the envelope. If your household is one where papers wander, punch the guide sheet and put it in a binder sleeve with a note of what you made, what size you cut, and what you would change. That note will be worth more to you in two years than the pattern itself.

Grainline, Fold Line, and Why a Skirt Twists

Of all the marks printed on pattern tissue, the grainline arrow decides more about how a finished garment looks than any other. Sew perfectly and cut off grain, and the garment will hang wrong forever. No pressing, no alteration, and no amount of skill at the machine will fix it afterward.

What Grain Is

Woven fabric is built from two sets of threads crossing at right angles. The lengthwise grain runs parallel to the selvage, the finished edge that runs the length of the bolt. These threads are held under tension during weaving and are the strongest and least stretchy direction of the cloth. The crosswise grain runs from selvage to selvage; it has a little more give. True bias is the 45-degree diagonal between the two, and it is where woven fabric stretches and drapes most freely.

Most garment pieces are cut with the lengthwise grain running vertically on the body. That is why a well-cut skirt hangs straight down and a well-cut sleeve does not corkscrew: the strongest, most stable direction of the fabric is running the direction gravity pulls.

The Arrow and the Bent Arrow

The grainline is printed as a long straight line with an arrowhead at each end, running through the pattern piece. Placed on fabric, that arrow must be exactly parallel to the selvage — not approximately, exactly.

The fold line is different. It appears as a line along the edge of a piece, marked with an arrow bent at each end that turns toward the edge, or with wording such as "place on fold." That edge must lie precisely on the folded edge of the fabric. The piece is printed only half, because the fabric fold supplies the other half; cut it as a separate open piece and you will end up with a bodice front cut in two halves, with a seam where there should be none. Never cut along a fold edge, and never let it float even a quarter inch off the fold, or a center front will be an inch too wide.

Placing the Grainline Accurately

Do it with a ruler, not with your eye. Lay the piece roughly in place. Measure from one arrowhead straight across to the selvage or to the fabric fold and note the distance. Then measure from the other arrowhead to the same edge. Pivot the piece until the two measurements are identical, then pin at both arrowheads before pinning anywhere else. Two equal measurements mean the arrow is parallel; anything else means it is not.

Half an inch of error over a long skirt panel is enough to produce a hem that dips and a side seam that spirals toward the front as the day goes on. That is the twisting skirt everyone has owned, and it usually came from a factory in a hurry rather than from bad fabric.

Squaring the Fabric First

Grain placement is only as good as the fabric under it. Before laying anything out, straighten the goods. Pull a single crosswise thread near the cut end and cut along the channel it leaves, which gives you a truly crosswise edge. Then fold selvage to selvage and see whether the cut ends line up square. If the fabric refuses to lie flat and square, it is off grain and can often be coaxed back by pulling firmly on the diagonal, corner to corner, or by pressing with steam while easing it true. Do this before cutting, because afterward it is too late.

That Which Is Crooked

"That which is crooked cannot be made straight." The Preacher was speaking of the world's own tangles, not of dressmaking, but the sentence is exactly true of cloth. A piece cut off grain is crooked in a way no later care can undo. You may sew it beautifully, press it with a good iron, and hang it a week, and it will still swing to one side. The remedy is not more effort at the end; it is honesty at the beginning, with a ruler in your hand and no hurry. Sewing teaches this humbling truth faster than most trades: some things must be gotten right at the start or not at all, and the wise worker slows down precisely where a mistake becomes permanent.

When Bias Is Wanted

Some pieces are meant to be cut on the bias, and their grainline arrow will be printed running diagonally across the piece. Bias-cut pieces stretch, drape softly, and mold around curves, which is why bias binding can go smoothly around a neckline that a straight strip would pucker. Handle bias-cut pieces gently, do not let them hang off the edge of the table under their own weight, and let a bias-cut skirt hang a full day before hemming, since it will drop unevenly and must be trimmed level.

Notches, Dots, and the Five-Eighths Inch

The tissue is covered with small marks, and each one is an instruction. Once you can read them, a pattern piece stops being a shape and becomes a set of directions about where things meet.

The Seam Allowance Is Already There

On patterns from the major American companies, the standard seam allowance is 5/8 inch, and it is drafted into the piece. The cutting line is the outer edge; the stitching line sits 5/8 inch inside it. Narrower allowances appear where a wide one would not turn cleanly: 1/4 inch is common on tight curves, on some armholes, on welt pocket details, and on necklines that will be bound. The guide sheet says so when it differs.

Because the allowance is included, you cut on the printed line. Adding a margin "for safety" makes every seam too wide and the finished garment smaller than the pattern intends, since your stitching line will still be 5/8 inch from the fabric edge but the fabric edge is now in the wrong place. Beginners do this constantly and then conclude the pattern runs small.

Some patterns, particularly certain independent and European ones, are printed with no seam allowance at all, or with a metric allowance such as 1 cm or 1.5 cm. The envelope or guide sheet always says which. Check before cutting; do not assume.

Notches

Notches are the small triangles or diamonds sitting on the cutting line at seam intersections. They are matching marks. When two pieces are pinned right sides together, the notch on one must sit exactly on the notch of the other, and if they do, everything between them will fall into place.

They also identify which edge is which. The widely used convention on the major pattern lines is a single notch on the front and a double notch on the back, so that a sleeve, which is easy to sew in backward, can be oriented at a glance. Additional groups of notches are used for other seams, and the guide sheet glossary tells you what each set means on that particular pattern.

Cut notches outward, as little triangles projecting past the cutting line, rather than clipping inward into the seam allowance. Outward notches survive; inward clips get lost in the fraying edge and can weaken a seam that is already narrow. If your fabric frays badly, mark the notch with a short snip no deeper than an eighth of an inch, or a chalk line, instead.

When notches do not match at the machine, stop. A sleeve cap that is a half inch longer than its armhole is meant to be eased, not stretched or gathered by force; pin at the notches and at the shoulder point first, then distribute the extra length in between with more pins. A seam sewn with notches ignored will look fine flat and hang badly on a body.

Dots, Squares, and Triangles Inside the Piece

Marks printed inside the body of the piece are placement points, not matching points on an edge. A dot may mark where a dart stops, where a zipper opening ends, where a pocket corner sits, where gathering begins and ends, or where you must pivot and stop stitching to turn a corner. Squares and small triangles are used the same way on some pattern lines, and again the glossary defines them.

These must be transferred to the fabric before the tissue comes off, because once the pattern is unpinned there is no way to find them again. Tailor's tacks made with a doubled thread through both layers are the traditional method and work on anything. A washable fabric marking pen, tailor's chalk, or a chalk wheel is faster; test any marker on a scrap first and be sure it comes out of your fabric. Carbon tracing paper with a tracing wheel works well on smooth wovens, on the wrong side only. Whatever you use, mark every dot on both layers.

The Hand of the Diligent

"The hand of the diligent shall bear rule: but the slothful shall be under tribute." Marking is the least interesting twenty minutes of any project, and it is precisely the twenty minutes that decides whether you rule the garment or the garment rules you. Skip it and you will spend an hour later guessing where a pocket goes, unpicking a dart that ended in the wrong place, and paying tribute in ripped stitches and tired patience. Diligence here is not fussiness. It is the practical difference between work that goes forward and work that goes back.

A Quick Order of Operations

Pin the piece down, cut on the line, cut notches outward as you go, and then — before unpinning — mark every dot and dart leg through both layers. Only then lift the tissue. Label your cut pieces with a scrap of masking tape naming the piece and, on symmetrical pieces, which side is which. Stack them in the order the guide sheet will call for them, and put a pin through the stack so a draft or a curious child cannot rearrange your afternoon.

Choosing and Following the Cutting Layout

Everything in this unit has been leading to one table and one hour of quiet work. The cutting layout is the pattern company's own solution to the puzzle of fitting your pieces onto your fabric, already worked out and drawn to scale. Following it is not a lack of independence; it is the sensible use of somebody else's careful arithmetic.

Finding the Right Diagram

The guide sheet carries a dozen or more small layout diagrams. Each is labeled with a view, a fabric width, and often a size range, plus separate diagrams for fabric with nap, for lining, and for interfacing. Find the one that matches all of your circumstances at once: your view, your width, your size group, and whether your fabric is napped. Circle it. Cross out the rest so your eye cannot land on the wrong one an hour later when you are tired.

Read the diagram's conventions before you use it. Shaded or gray pieces mean the piece is to be laid printed side down on the fabric. White pieces lie printed side up. A piece drawn extending past the fold line with a dashed outline is to be cut after the fabric is unfolded, or cut from a single layer. The layout also shows exactly how the fabric is folded: lengthwise fold with selvages together, crosswise fold, double fold with both selvages meeting at the center, or a single open layer.

Fold the Fabric the Way the Diagram Shows

This is where people improvise and lose. A lengthwise fold and a crosswise fold are not interchangeable, because they present different amounts of width and they change which direction the lengthwise grain runs on the cut pieces. A double fold exists so that two mirror pieces can be cut on two folds at once. Fold as drawn, right sides together unless the diagram says otherwise, and smooth the layers flat without stretching. Check that the selvages lie exactly together along their whole length; if one creeps, the whole layout goes off grain.

Nap, Direction, and Prints

If your fabric has a nap, a sheen, a one-way print, or a shading that changes as you turn it, use the with-nap layout, in which every piece points the same direction. Stand back and run your hand down corduroy or velveteen: one direction feels smooth, the other resists, and the two catch light so differently they look like different colors on a finished garment. The same care applies to a print with an obvious top and bottom. Nothing looks more like a mistake than one sleeve of upside-down tulips.

Pin, Then Cut

Lay all pieces out before you cut a single one. Confirm every piece for your view is on the fabric and that nothing is hanging off an edge. Set grainlines with a ruler as you go, pinning each arrowhead first. Then pin the rest, about every three to four inches, with pins inside the cutting line and set parallel to the edge, so the shears can pass. Pattern weights and a rotary cutter work faster than pins and shears on stable fabrics; either is fine.

Cut with long, smooth strokes, keeping the lower blade of the shears on the table and never lifting the fabric. Lifting distorts the layers and makes the top piece bigger than the bottom one. Cut notches outward as you reach them.

Rotary cutters deserve real respect: the blade is genuinely sharp, it must be used with a self-healing mat, and the guard should be closed every single time you set it down, without exception. A rotary cutter left open on a table is the most dangerous thing in an ordinary sewing room, especially with children in the house.

Take Heed How You Build

Paul says he laid a foundation as a wise masterbuilder, and that another builds on it, and then adds the warning: let every man take heed how he buildeth thereupon. That is the cutting table exactly. The drafter laid a foundation, tested and graded and printed. You build on it. Every stitch of the rest of the project rests on what you do in this one hour, and no later skill can compensate for a piece cut short or cut off grain. Take heed how you build. Work when you are rested, on a table you can walk around, with the door shut and nobody asking you questions. There is no hurry that is worth what a hurried cut costs.

Before You Sweep Up

Do not throw the scraps away until the garment is finished. You will want them for testing a stitch length, for testing an interfacing bond, for a bias strip you did not plan, or for a pocket you decide to add. Keep a labeled bag of leftovers from every project; the day comes when you need a facing and the store no longer carries the goods.
