I heard that you can make a finger protector in leather to use when sewing and that they work really great, so of course I had to try it. They DO work great.
I used a holepuncher intended for fabric to create the holes that i sewed in, with thin-ish yarn.
It's not super pretty, but it works!
No, this is not saddle stitch, sorry I was a bit unclear :) It's some sort or cross stitch
