Lesson 1
For which of you, intending to build a tower, sitteth not down first, and counteth the cost, whether he have sufficient to finish it?
Luke 14:28
Needle, Thread, and Knot: The Foundation of Every Fastener
A button that falls off after two weeks was almost never sewn badly. It was sewn with the wrong thread, or with a knot that slipped, and the stitching had no chance from the first pass. Before you touch a button, a snap, or a hook, settle three things: what thread, what needle, and how you will start and stop. The Lord Jesus spoke of a man who counts the cost before he builds a tower. The same plain wisdom applies at the sewing basket. Five minutes spent choosing thread saves an hour of resewing.
Reading thread by its number
Thread weight runs backward from what you would expect: the lower the number, the thicker the thread. A 100 weight is a gossamer thing used for fine applique. A 50 weight is the everyday thread most people piece and seam with. A 40 weight is noticeably stouter. Ordinary garment seams are usually sewn somewhere in the 40 to 50 range, and that is fine for seams, because a seam spreads its load along inches of stitching.
A fastener does not spread its load. Every time you button a coat, the whole pull of that closure lands on a few crossings of thread the size of a pin. So fasteners want something heavier. Button and carpet thread, sold on small spools in the notions aisle, is made for exactly this. Buttonhole twist is the other traditional choice: a glossy, twisted silk thread, smooth and pliable, that slides through fabric without dragging. Manufacturers number their heavy threads differently, so do not shop by the number alone. Hold a strand against your regular sewing thread. If it is visibly thicker and does not fuzz when you tug it, it will serve.
If you have no heavy thread in the house, double your regular thread. Cut a length, pass it through the needle, and bring the two cut ends together so you are sewing with two strands. Doubled thread is a genuine improvement over single, and for shirt buttons and light dress closures it is plenty. For a winter coat, buy the button thread.
Choosing the needle
Hand needles for this work are sharps or betweens. A sharp is a medium-length needle with a keen point, the general workhorse. A between is shorter, and short needles are easier to control when you are making many small stitches in one small spot, which is precisely what a button is. Keep both.
Size by two tests. First, the eye must take your thread without you forcing it; forcing shreds the thread before you have sewn a stitch. Second, the shaft should pierce the cloth without a struggle. A needle too fine for the job will bend or snap in heavy twill, and a needle far too coarse enlarges the holes so the button works loose and spins. On machine needles the same logic is printed on the packet, running from 70/10 for lightweight goods, through 80/12 for medium wovens and 90/14 for heavy cotton and twill, up to 100/16 for coat and upholstery weights. Read your hand needles the same way, finer for fine cloth, stouter for heavy.
One more point: when you will be stitching through the punched holes of metal hardware, use a genuinely sharp needle. A dull point skips, slides off the metal, and breaks thread. And wear a thimble. Pushing repeatedly against a needle head with a bare fingertip is how people end up with a needle through the finger.
Starting and stopping
Begin on the wrong side of the fabric. Knot the thread end, take one small backstitch right where the fastener will sit, and pull the knot snug against the cloth. That backstitch, not the knot, is what really holds; knots alone slip out of loose weaves. For thread that must not move at all, use a surgeon's knot, which is an ordinary overhand knot with the working end passed through the loop twice before tightening. The extra wrap keeps it from creeping open while you tension it.
Finish the same way in reverse. Bring the needle to the wrong side, take two or three tiny backstitches into the cloth beneath the fastener, knot against the fabric, and bury the tail by running the needle an inch through the layers before you cut. Never knot on the right side, where the knot rubs, shows, and works loose.
What goes wrong
Thread that frays as you sew is too long. Work with lengths of about eighteen inches; anything longer tangles and abrades passing through the cloth. Thread that shows as a dark shadow on pale fabric is the wrong color, and matching the layer underneath the closure is often better than matching the top. Thread that snaps mid-button was single, ordinary, and asked to do a heavy thread's work.

In thread weight numbering, a lower number means the thread is:

Everyday garment seams are usually sewn with thread in roughly which weight range?
- 100 to 120
- 80 to 100
- 40 to 50
- 18 to 20
Answer
C. 40 to 50
Why does a fastener need heavier thread than a seam?
- Fasteners are sewn faster
- The load lands on a few crossings instead of spreading along inches
- Heavy thread is easier to knot
- Fasteners are always on heavy fabric
Answer
B. The load lands on a few crossings instead of spreading along inches

Answer
A. A between
What happens if the needle is far too coarse for the cloth?
- The thread will not fit the eye
- The knot slips to the right side
- The thread doubles itself
- It enlarges the holes so the button works loose and spins
Answer
D. It enlarges the holes so the button works loose and spins

- Sewing should be expensive
- Towers were sewn, not built
- Only skilled builders may sew
Answer
A. Preparation before you begin saves the work later
