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.
I'd never known this was a thing I could do! I'll have to look into this as I have a good few comfy warm socks that could use repairing!
I’d say just be sure to check out a video tutorial first if you’re not already pretty familiar with weaving, but it’s not hard to do at all!
