I consider a scrap anything under a yard THAT I PREVIOUSLY USED IN A QUILT PROJECT. I purposely buy fat quarters and would not consider them a scrap, though I know that "scrap quilt" books and patterns are very often based on fat quarters. but once I've used it in something, it becomes a scrap. I just went through my scraps and cut them into 5" squares and 2 1/2" strips that are now ready to go.
