Reading about how people cut their scraps makes me wonder what actually constitutes a scrap. If I have a chunk of fabric big enough for a 10" square, or WOF pieces, I don't consider them scraps and keep them with my stash. Well, sort of. I keep those bigger pieces with my fat quarters. Are they scraps?
Scraps for me go into one of those portable drawer kits - each drawer is about 8x10 with 2" height. Four drawers - light, dark, medium & specialty. When they get full, it's scrap quilt time.
