Darning and Patching: Repairing Cloth Instead of Replacing It

A hole grows. The threads around its edge are already weakened, and every wear cycle pulls more of them free — which is why a small hole becomes a big one surprisingly fast. Work a ring of small running stitches around the hole, a centimetre or so out into sound fabric, before you start. That stops it spreading while you work and gives the repair something solid to attach to. Trim away any loose or frayed threads at the edge, but do not cut into sound material to 'tidy' the hole. Every millimetre you cut is a millimetre the repair has to span.

Stretch the area over a darning mushroom or an embroidery hoop so it is flat and under slight tension. Lay a set of parallel threads across the hole, anchored well into the sound fabric on each side. Then weave a second set at right angles through the first — over, under, over, under — exactly as a loom does, reversing the alternation each row. What you are making is a small piece of woven cloth occupying the hole, and it behaves like cloth rather than like a lump of thread. Keep it loose. A darn pulled tight puckers the surrounding fabric and then tears at its own edges, which is where a failed darn almost always goes.

An applied patch sits on the outside and is sewn down around its edges. It is strong, quick, and visible — which is fine on workwear and is the whole aesthetic of sashiko and boro mending. An inset patch goes BEHIND the hole, and the edges of the hole are turned under and stitched down onto it. It is far less visible and takes longer. Match the patch to the garment: same fibre, similar weight, and pre-washed so it does not shrink differently on the first wash. And cut it on the same grain — a patch cut on the bias stretches differently from the cloth around it and ripples after a few wears.

The best repair is the one done before the hole. A thin patch of fabric sewn behind an elbow, a knee or a heel that is going shiny takes minutes and prevents the hole entirely. Learn where things wear: elbows, knees, seat, heels and toes, cuff edges, collar folds, and wherever a strap or a pocket rubs. Those are the same few places on nearly every garment, and they are visible as thinning long before they open. This is the textile version of the maintenance rung from sharpening: attend to it on a schedule rather than after a failure, and the object lasts several times as long for a fraction of the work.
