When I use my 12ish old pelts for sewing a blanket what thread should I use? I've been trying to follow many of the posts on here for a bit so I've seen to use a denim needle and anywhere from nylon thread to cotton thread. I've read that nylon thread may sit there and cut through the material after extended use though and I just can't see cotton thread as being too sturdy to go through washes or extended uses, though I've never done anything like this before and have no clue what I'm talking about. :?
