Lesson 1
And look that thou make them after their pattern, which was shewed thee in the mount.
Exodus 25:40
Measuring the Bed and the Pillow Before You Cut
Bedding is forgiving in one way and unforgiving in another. The seams are long and straight, so the sewing is easy. But a pillowcase cut two inches short is firewood, and a quilt top pieced to the wrong width will never hang right on the bed no matter how beautiful the blocks are. The work of this unit begins with a tape measure, a pencil, and ten quiet minutes.
Moses was told to make the furnishings of the tabernacle after the pattern he had been shown. He was not asked to improve on it or to guess at it. That is a fair picture of the discipline this craft asks of us: measure what is actually there, write it down, and build to those numbers.
Measure the Pillow, Not the Old Case
The most common mistake in home bedding is measuring the pillowcase you already own. That case has shrunk, stretched, and been pulled out of square for years. Measure the pillow itself, lying flat and lightly patted down, from seam to seam.
Standard US pillow sizes give you a starting point. A Standard pillow is 20 by 26 inches. A Queen pillow is 20 by 30 inches. A King pillow is 20 by 36 inches. European pillow sizes vary considerably; 40 by 80 centimeters is common on the continent, and square pillows are also sold, so if you are sewing for imported pillows, measure rather than assume.
A pillow is not flat. It has depth, and depth eats width. Add about one inch of ease across the width and about two inches to the length so the pillow slides in without straining the seams. A case sewn to the exact size of the pillow will look strained, wear out at the corners first, and fight you every laundry day.
Adding Seam and Hem Allowances
Ease is not seam allowance. They are two separate additions and you need both.
For the long straight seams of bedding, 5/8 inch, or 15 millimeters, is the traditional allowance. It is generous enough that the raw edges inside can fray a little without the seam letting go. For enclosed seams like the French seam you will meet shortly, work at 1/4 inch, or 6 millimeters, on the first pass. Curved edges take the narrower allowance too, because a wide allowance cannot lie flat around a curve.
The open end of a pillowcase needs a deep hem, not a narrow one. A hem of about 4 inches, folded double so the raw edge is buried, gives the mouth of the case body and keeps it from rolling. That means adding roughly 8 inches to your cut length for the hem alone, plus the ease, plus the seam allowances at the closed end.
Write the arithmetic down and check it against a real case. Take a Standard pillow, 20 by 26 inches, a single rectangle folded so that two of its edges meet, one seamed edge, one folded edge, and a four inch doubled hem at the mouth. Half the cut width is 20 inches of pillow, plus 1 inch of ease on the flat width, plus 5/8 inch of seam allowance on the one edge that gets seamed: 21 5/8 inches. Doubled, that is a cut width of 43 1/4 inches, which still fits across 44 inch goods. The cut length is 26 inches of pillow, plus 2 inches of ease, plus 5/8 inch for the seam across the closed end, plus 8 inches swallowed by the doubled hem: 36 5/8, so cut 37 and stop fussing. Show your own work rather than trusting mine.
Sizing a Quilt or a Duvet Cover
For a duvet cover, measure the insert flat, then add about one inch of ease in each direction and your seam allowances on top of that. A cover cut too snug compresses the fill, and a compressed duvet is a colder duvet.
For a quilt, measure the mattress top, then decide the drop, which is how far the quilt hangs down each side. Add the drop twice to the width, once to the length for the foot, and add a little at the head for the pillow tuck if you want one. Then measure your own mattress rather than trusting a size chart, because mattress depth has grown considerably over the years and a pillow-top mattress swallows several inches of drop.
Remember that quilting itself draws the quilt up. Dense stitching through three layers pulls the top in, sometimes noticeably, so cut the layers with a few inches of extra all around and trim square after quilting.
Write the Cutting List
Before any blade touches fabric, make a list: piece name, cut size, how many. Then check it against the fabric you have. Quilting cotton usually runs 44 to 45 inches wide, which will not cross a bed in one piece, so quilt backs and duvet panels normally need a seam or a wide backing fabric sold for the purpose.
Cut with a rotary cutter on a mat, blade guard closed the instant you set it down, fingers behind the ruler edge and never in front of it. A rotary blade will open your knuckle before you feel it. Measure twice; the second measurement costs nothing.

What are the dimensions of a Standard US bed pillow?
- 20 by 30 inches
- 20 by 26 inches

- 20 by 36 inches
Answer
B. 20 by 26 inches
Why should you measure the pillow itself rather than an old pillowcase?
- Old cases are always cut oversized on purpose
- Pillowcases are never made to a standard size
- The old case has shrunk, stretched, and pulled out of square over years of use
- Pillows and cases use different units of measure
Answer
C. The old case has shrunk, stretched, and pulled out of square over years of use
What seam allowance is described as traditional for the long straight seams of bedding?
- 5/8 inch, or 15 millimeters
- 1/8 inch, or 3 millimeters
- 1 inch, or 25 millimeters
- 1/4 inch, or 6 millimeters
Answer
A. 5/8 inch, or 15 millimeters
In Exodus 25:40, what was Moses told to do?
- To make the things after the pattern shewed him in the mount
- To measure the tabernacle with a reed
- To choose whatever fabric seemed best to him
- To teach the people to spin flax
Answer
A. To make the things after the pattern shewed him in the mount
Roughly how much extra length should you add for a pillowcase hem folded double at about four inches deep?
- About 2 inches
- About 4 inches
- About 12 inches
- About 8 inches
Answer
D. About 8 inches
Why add about an inch of ease across the width of a pillowcase?
- Because thread shrinks in the wash
- Because a pillow has depth, and depth eats width
- Because the hem pulls the case narrower
- Because cotton always stretches on the bias
Answer
B. Because a pillow has depth, and depth eats width
What is meant by the drop of a quilt?
- The amount the quilt shrinks in the first wash
- The looseness of the batting inside the layers
- How far the quilt hangs down over the side of the mattress
- The distance between quilting lines
Answer
C. How far the quilt hangs down over the side of the mattress
Why should a quilt sandwich be cut with a few extra inches all around?
- Because batting is sold only in oversized pieces
- Because quilting through three layers draws the top in and the edges must be trimmed square afterward
- Because binding is always cut from the excess
- Because the backing must be folded to the front
Answer
B. Because quilting through three layers draws the top in and the edges must be trimmed square afterward
Why does a quilt back or duvet panel usually need a seam?
- Because a single piece would be too heavy to quilt
- Because seams add necessary strength across the middle
- Because backing fabric is sold only in narrow strips
- Because quilting cotton usually runs only 44 to 45 inches wide, which will not cross a bed
Answer
D. Because quilting cotton usually runs only 44 to 45 inches wide, which will not cross a bed
