Yes I have used them before. Don't know about pilling, it was on a charity quilt. It does stretch a little, but not to much. Just don't pull it to much. Also make sure you have a new sharp needle, the thread kept breaking until I changed the needle. If I had a bigger needle I would have put that on. If I can find the picture I will post. After it was washed turned out really nice. Also I didn't use batting, I thought it would be to heavy.
Good Luck
