If it's cuts off triangles I sew them together to make HSTs. I save most small scraps of fabric until I'm done working on that particular quilt then they're gone. I used to give them to a "friend" because she'd asked if I would give her my scrappy pieces, some were as big as fat eighths, until I overheard her tell someone that I was gave her all my garbage. Now, I keep the bigger pieces and the small ones go in the garbage.
