Darning a sock, trailhead-style

Okay. Last couple lessons we were reinforcing thin spots before they opened up on us. Today they've opened up. You've got an actual hole in a sock or a knit sleeve, and we're going to close it properly with a darn instead of just yanking thread across the gap and hoping.

Darning is not the same stitch family as the hemming and patching we've done so far. It's a woven repair — you're basically rebuilding a little patch of fabric with thread, the way the original fabric was built. It sounds fussy. It isn't, once your hands know it.

Why socks specifically, and here's why

Socks wear through at the heel and the toe because that's where the friction and stretch happen. A woven cotton shirt tears in a line. A knit sock wears thin in a spot and then opens into a hole with soft, stretchy edges — there's no clean tear to work with, just a weak patch that keeps getting weaker. That's why we don't patch it like fabric. We darn it, which means weaving new thread through the good fabric around the hole until the hole has a floor again.

What you need

A darning needle if you have one — blunter tip, bigger eye. A regular hand-sewing needle works fine too, don't let a missing tool stop you.
Sock-weight thread or embroidery floss. Regular sewing thread is too thin and will saw right through a stretchy knit. This is one place I'll actually tell you to go a size up from what you'd use elsewhere.
Something round to put inside the sock while you work — an actual darning egg if you own one, a light bulb if you're my mother's generation, or honestly a smooth rock or a closed jar lid. You need something to hold the hole's shape so you're not sewing the sock shut on itself.

The steps

Turn the sock right side out and find the hole. Put your round object inside, right under the hole, so the fabric is taut but not stretched tight.

Trim any raggedy loose threads around the edge of the hole. Don't pull on them first to "see how bad it is" — that's how a dime-sized hole becomes a quarter-sized hole.

Starting about a half inch out from the hole in good fabric, run stitches straight across the hole and out the other side, in parallel lines, like you're stringing a tiny loom. Don't pull tight — these are your foundation threads and they need some give, because a sock has to stretch around a foot.

Once you've got a full set of parallel lines covering the hole, turn and weave a second set of stitches at a right angle, going over one thread and under the next, back and forth, building a woven patch right over the gap.

Keep the tension loose and even. Tight thread will pucker and then you've made a lump inside somebody's shoe, which is its own kind of misery.

Weave your last stitch off into the good fabric at the edge, same as tying off any thread, no knot sitting inside the sock where a toe will find it.

I'll tell you the same thing I tell people about hems: pin it, look, then sew. With darning that means get your egg or your rock in place and check the hole's actual size before you start weaving, because the shape shifts once fabric relaxes.

Here's the opinion I'll stand on with this one: a visible mend is not a failure. Nobody's darn is invisible. You will be able to see where it happened. That's fine. A woven patch on the heel of a wool sock is honest work and it holds up through a hundred washes, and there is nothing wrong with a sock that shows it's been loved.

I did one of these sitting on a rock at the bottom of a canyon trail once. Wore a hole clean through my hiking sock about three miles in, felt it rubbing before I saw it, and I'd packed a needle and a little card of thread in my hiking bag same as I pack everything else — habit, not planning. Pulled the sock off, sat down, darned it right there while my husband and I ate our trail mix. Couple next to us on the rocks thought that was the funniest thing they'd seen all day. I finished the hike in that sock and it held the rest of the trip. Didn't slow us down, didn't blister, and I've carried a needle and thread on every hike since, same little card, same spot in the bag.

You don't need fancy gear for this. You need a needle, some decent thread, and about fifteen minutes of patience with a stretchy little hole that wants to fight you.

Before next time

Find a sock with a hole in it — you've got one, everybody's got one — and darn it before our next session. If you don't have a darning egg, a rock or a light bulb genuinely works fine. 🌷
