The inside patch that disappears (don't sew the leg shut)

Okay. Last time we did the visible patch, the honest one, right on top where everybody can see it. Today's the opposite job. Same basic idea, patch fabric behind a hole, but this time the goal is nobody ever knows it happened. Sunday best mending.

And here's why this lesson comes with a story attached instead of just steps. The first time I ever tried an inside patch, I sewed the pant leg shut. Oh my heck. Whole leg. Sewed the front of the fabric to the back of the fabric like I was closing up a pillow, felt very proud of myself, flipped it right-side out to admire my work, and discovered I had made a pant-shaped pocket that no leg would ever fit through again. Had to cut the whole thing back open and start from the pin. I tell people this because you are going to do a version of this same thing today if you're not careful, and I would like you to feel dumb for about four seconds instead of feeling dumb for the rest of the class.

What we're doing and why

A visible patch sits on top of the hole, out in the open, and that's honest and I like it plenty. But for church pants, a good shirt, anything where you want it to look like nothing ever happened, the patch goes on the inside. You slide it behind the hole, stitch around the edges of the hole itself, and the patch never shows from the front.

The whole trick is that you are only ever sewing through two layers on purpose: the garment fabric and the patch fabric behind it. Not through to the other side of the pant leg. Not catching a fold of fabric you didn't mean to catch. Two layers, and you have to keep checking that it's two layers the whole time, because fabric likes to fold in on itself when you're not watching it.

Steps

Turn the garment inside out. This whole repair happens from the wrong side of the fabric, which trips people up because your instinct is to work from the front. Resist it.

Flatten the hole and look at the shape of it. Don't pull it taut, don't stretch it — let it lie the way it wants to lie. Note where the edges are.

Cut your patch fabric at least an inch bigger than the hole on all sides. Bigger than you think. A patch that's too small just gives you a smaller hole to deal with in six months.

Slide the patch behind the hole, from the inside. Now — and this is the part that gets people — reach your hand INTO the garment first if it's something like a pant leg or a sleeve, so you can feel that there's only the one layer of patch fabric sitting there, not the front and back of the leg pinched together. Feel it with your fingers before you pin anything.

Pin the patch in place, flat, centered behind the hole. Then look. Then look again. Pin it, then look, THEN sew — that's not just a saying I like, that's the only thing standing between you and a sewn-shut pant leg.

Stitch around the edges of the hole, working through the garment fabric and the patch behind it only. A small whip stitch or slip stitch, whichever you're comfortable with — small stitches, close together, snug to the edge of the hole so it doesn't fray further.

Check as you go. Every few stitches, reach in with your other hand and confirm you're only catching two layers. This is not paranoia, this is the lesson.

Turn it right-side out and look at the front. This is the payoff moment. If you did it right, you should barely see a thing — maybe a slight shadow of the patch color underneath if you're looking for it, and you're the only one who's looking for it.

The opinion part

I'll say it again because it's true here same as everywhere else: you do not need to be good at sewing to save this shirt. This patch does not require fancy stitchwork. It requires you to slow down at the pinning step and check your layers before you start pulling thread through anything. That's it. That's the whole skill.

And a word about hurrying

Zachary came to me at 9 o'clock at night once needing a costume cape hemmed for school the next morning, and I did it, and I also told him — while I was doing it — that this is exactly how mistakes happen, rushing a mend in bad light with no time to fix it if you mess up. I fixed his cape fine. But an inside patch done at 9 p.m. with your patience worn thin is a pant leg sewn shut. Give yourself real time for this one, especially your first try.

Before next time: find one hole in something you don't love too much — an old t-shirt, a sock you were about to toss — and practice the inside patch on it before you do it on something that matters. Better to sew a scrap leg shut than a good pair of pants.
