Most home-sewn jackets fail at the lapel, and the collar isn’t usually the cause. They fail because the lapel was pressed flat and then expected to roll afterwards. A tailored lapel is shaped while it is still only canvas and cloth basted together. The shape comes from three things working at once: a taped roll line, pad stitches that bind the canvas to the cloth in a curve, and the hand you hold underneath while you sew.

Start with the right canvas. For a mid-weight worsted suiting I use a wool-and-goat-hair canvas of about 200 g/m², with a separate chest piece of horsehair (crin) laid over it from the shoulder to just below the bust point. Cut the front canvas on the same grain as the jacket front, and trim the lapel portion back to the roll line plus 3 mm. Any canvas beyond that line would stiffen the part that is meant to turn. Pre-shrink everything. Dip the canvas in warm water and line-dry it. Steam the cloth on the wrong side under a damp press cloth until it stops moving.

Tape the roll line before a single pad stitch goes in. Lay 1 cm linen stay tape with its outer edge just on the roll line, and pull it tight as you baste it. On a 40 cm roll line for an average chest, I hold the tape about 6 mm short over its full length, and up to 1 cm short for a fuller chest. Fell both edges of the tape to the canvas with small diagonal stitches. That tension is what draws the lapel in against the body. Without it, the front gapes the moment the wearer lifts an arm.

Now the pad-stitching. Work from the canvas side, in rows parallel to the roll line, starting at the tape and moving out toward the lapel edge. Each stitch is a short vertical bite that picks up a single thread of the cloth and no more. The travel between bites makes the diagonal you see on the canvas side. Alternate direction from row to row and you get the chevron; keep going in one direction and you get diagonal rows, which are slightly quicker and hold just as well. Near the roll line, make stitches about 8 mm long with rows 8 mm apart. Toward the point, shorten both to 5 mm so the outer edge holds a firmer, tighter curl.

The stitches only shape the lapel if the layers are curved while you sew. Hold the lapel rolled over the forefinger of your left hand, cloth side down, so the canvas is on the outside of the curve. Each stitch taken with the layers bent this way fixes a little more canvas than cloth, and when you let go the lapel keeps the bend. It feels awkward for the first row. By the fourth row, you’ll see the work curl on its own when you put it down. Use a size 9 between needle and a silk thread close to the cloth colour, because a few bites will always show on the face.

When the rows are done, press on a tailor’s ham with the lapel still in its roll, never flat on the board. Steam through a damp cotton cloth, then bring the clapper down and hold it for a count of ten so the wool sets as it cools. Leave the front on the ham overnight. In the morning, trim the canvas back 3 mm from the lapel edge and tape the front edge too, easing the tape slightly at the point. The cloth then goes over a lapel that already knows where it wants to fold, so the iron only has to confirm it.

A full lapel in this weight takes me about two hours and something like 600 stitches. That is the part beginners want to skip, and it is also the part a fused front can’t imitate. Fusing makes a lapel flat and firm, and a flat, firm lapel has to be forced into its roll with the iron. That forced roll lasts until the first dry clean. A pad-stitched roll is in the structure, and it will still be there after the jacket has outlived its first owner.
