Lesson 1
A just weight and balance are the LORD'S: all the weights of the bag are his work.
Proverbs 16:11
Counting the True Cost of Cloth and Notions
Before you can name a price, you have to know what the piece cost you to make. Most home sewists guess, and most guesses run low. The fabric is remembered because it came with a receipt; the zipper, the interfacing, the two spools of thread, and the yard you cut wrong are all quietly forgotten. Those forgotten items are exactly where the profit goes.
Start With a Cost Sheet, Not a Memory
Give every paid project its own sheet of paper or its own line in a notebook. At the top write the client's name, the garment, and the date. Underneath, list every purchase as you make it, with the price you actually paid, not the shelf price and not the price you wish you had paid. If you bought three yards at $12.99 and used two and a half, charge the project for all three unless the leftover is genuinely large enough to be a usable piece for something else. Scraps under a quarter yard are a cost of the job, not inventory.
Include sales tax and shipping. A $9 zipper set with $8 shipping is a $17 zipper. If you drove forty minutes to a fabric store for one project, that trip belongs on the sheet too, even if you only note it as a flat travel charge you set for yourself.
The Notions Nobody Counts
Notions are the small hardware and supplies of the trade: thread, zippers, buttons, hooks, snaps, elastic, interfacing, twill tape, bias binding, trim. On a typical garment they add roughly ten to twenty-five dollars, and they are the single easiest cost to underestimate. A shirt with eleven buttons, fusible interfacing for two collar pieces and a stand, and a second spool of thread for the buttonholes has spent real money before you touched the machine.
Thread deserves its own note. A full-size spool does not sew one garment and then die, but it does not last forever either. A workable habit is to count one new spool per project in the color you had to buy for it, and to treat black, white, and gray as shop supplies you replace out of overhead rather than billing each time.
Interfacing is the other quiet drain. It is sold by the yard, it is used in small pieces, and it goes stale in a drawer. Buy it in useful widths, cut it carefully, and write down what a garment's worth of it costs you so you stop guessing.
Waste, Test Seams, and Ruined Pieces
Every honest cost sheet has a line for waste. Cutting a plaid or a one-way print costs extra yardage, sometimes half a yard or more, because the pieces cannot be nested tightly. Napped fabrics like velveteen and corduroy must all run the same direction, which costs the same way.
Test seams cost fabric too. Before you sew a client's silk with a 70/10 microtex needle, you sew a scrap of the same silk to check the tension and confirm the needle is not snagging. That scrap comes out of the yardage. So does the collar you cut backward at ten o'clock at night. Build a small allowance for error into the material total rather than pretending you will never make one, because you will, and the client should not be the one who pays for it twice.
Two Honest Ways to Mark Up Materials
There are two common approaches, and you should pick one and stay with it. The first is a straight retail-style markup of two to three times material cost, used when you are selling a finished item off a table with no separate labor charge. The second, better suited to custom work, is a conservative markup of about 1.25 to 1.5 times fabric cost, with labor billed separately by the hour. The modest markup covers your shopping time, your storage, and the pieces that never sell.
What you must not do is apply both a heavy retail markup and a full hourly labor charge on the same piece. That is not shrewd, it is double-dipping, and customers notice. Scripture ties honest measure directly to the character of God: a just weight and balance are His. A cost sheet kept truthfully is a small act of worship, and it also happens to be the only way you will ever know whether your work pays.

Answer
B. $10 to $25
Which of these counts as a notion?

Answer
A. Interfacing, elastic, and hooks
A $9 zipper set arrives with $8 shipping. What should the cost sheet record?
- $9, since shipping is overhead you ignore
- $17
- $4.50, because half the set is left over
- Nothing, because notions are too small to track
Answer
B. $17
Why does cutting a plaid or a one-way print cost more in fabric?
- The fabric is always more expensive per yard
- The pieces cannot be nested tightly, so extra yardage is needed
- Plaids require a special needle that wastes thread
- It must be cut on the crosswise grain only
Answer
B. The pieces cannot be nested tightly, so extra yardage is needed
What is the recommended conservative markup on fabric cost for custom work where labor is billed separately?
- No markup at all
- About 1.25 to 1.5 times
- About 4 times
- About 10 times
Answer
B. About 1.25 to 1.5 times
The two-to-three-times retail markup is best suited to what?
- Alterations on a client's own garment
- Fitting appointments
- Selling a finished item with no separate labor charge
- Charging for pattern drafting
Answer
C. Selling a finished item with no separate labor charge
What does the material teach about combining a heavy retail markup with a full hourly labor charge on the same piece?
- It is standard practice and should always be done
- It only applies to alterations
- It is required to cover insurance
- It is double-dipping and should be avoided
Answer
D. It is double-dipping and should be avoided
Why sew a test seam on a scrap of the client's silk before starting?
- To check tension and confirm the needle is not snagging
- To use up leftover thread
- Because silk cannot be pinned
- To pre-shrink the fabric
Answer
A. To check tension and confirm the needle is not snagging
Which needle was named for testing a fine silk?
- 100/16 jeans
- 90/14 universal

Answer
D. 70/10 microtex
Proverbs 16:11 says a just weight and balance are the LORD'S. How is that applied here?
- Fabric should be weighed rather than measured by the yard
- It means prices should never change
- Keeping a truthful cost sheet is honest measure, and the only way to know if the work pays
- It forbids charging for handmade goods
Answer
C. Keeping a truthful cost sheet is honest measure, and the only way to know if the work pays
