What You Need
Needle (a thick one with a big eye)
Embroidery thread or regular thread doubled up
Scissors
The thing you're fixing
A patch of fabric if the hole is big
That's it. Everything else is just practice.
Things to Know Before You Start
Pick the wrong thread and you'll regret it. Too thin and it breaks while you're sewing. Too thick and it won't go through the fabric. I've done both. Start with standard embroidery thread. It works on almost everything.
Don't pull too tight. Every beginner does this including me. Tight stitches make the fabric bunch up. You want the mending to lie flat. Loose is better than tight. You can always go back and tighten a little. You can't unstretch a pulled seam.
Wash the piece first. I skipped this once and the mended spot shrank different from the rest of the shirt. Looked weird. Still looks weird. Wash and dry the way you normally would before you start sewing.
Good light matters more than you think. I tried mending a black sweater at night under my kitchen light. Couldn't see the holes. Missed half of them. Next morning in sunlight I saw everything I'd skipped. Now I only mend by the window.
Keep your first few tries on things nobody sees. An old pillowcase. The back of a shirt collar. Underarm seams. You'll make mistakes. That's fine. Just don't make them on the front of your favorite jacket.
Five Mends and What I Learned
Sashiko on a denim knee
I ripped a pair of jeans last winter. Right knee, small hole. I'd seen sashiko online so I tried it. White thread on dark denim. Rows of little running stitches spreading out from the hole like sun rays.
What I'd do differently: Use thicker thread. The regular embroidery thread I used looks too delicate for denim. Next time I'll use actual sashiko thread or double up what I have.
Woven darn on a wool sock
The heel of my favorite gray sock wore thin. I learned woven darning from a YouTube video. You weave thread back and forth one way, then the other way, building new fabric over the thin spot.
What I'd do differently: Match the color better. I used light gray on dark gray. The repair is obvious. Fine for socks nobody sees. But for something visible, I'd get a closer match.
Patch behind a torn shirt collar
A button-down shirt tore right where the collar meets the body. Too small to sew closed. I cut a square of white cotton and sewed it behind the tear. Then did little straight stitches across the tear itself to hold everything flat.
What I'd do differently: Shape the patch smaller. I made it two inches square. A one-inch patch would have been plenty. Less bulk behind the collar.
Blanket stitch around a frayed cuff
My favorite linen shirt started fraying at one cuff. I did blanket stitch all the way around the edge. The stitches look like little loops. Keeps the fabric from fraying more and adds a nice border.
What I'd do differently: Practice on scrap first. My first few stitches were uneven. The spacing got better as I went. But the beginning of the cuff looks different from the end. Nobody notices except me and now you.
Running stitch over a pulled seam
A dress had a seam that was coming apart near the armpit. Not torn open, just loose. I did simple running stitch over the whole seam section. Tiny in and out stitches following the original seam line.
What I'd do differently: Backstitch instead. Running stitch is fine. Backstitch is stronger. I learned that after I finished. I'm leaving it. But next time I'll do backstitch from the start.
The whole point of visible mending isn't to hide the repair. It's to make the repair part of the piece. Every wrong stitch is just texture.
Pick something small and broken. Try one of these. Put a picture in the comments. I want to see what you fixed.
