My first attempt doesn’t look as nice, since I was trying to sew down the last loops of the warp one at a time instead of taking them all off the hooks at once and then sewing them down.
I think this one turned out alright, though! I just used some variegated craft thread that looked about the same size as pearl thread, but was cheaper and came in a variety pack.
That’s very nicely done. You’ve inspired me to have a look at getting one of these little hand-sized mending looms :)
Thanks! If it helps your search, this was made with a 14 hook loom, which is a good size for mending small holes (~1”).
