The cash register roll would be a good way of storing your tiny scraps. When you're done with a quilt and have a bunch of bits left, take some time to sew them out onto a roll. Easy-peasy to store them and they don't wrinkle. Then when you feel like using them, make a quilt like huntannette has above! So nice! You could even start several rolls if you wanted to segregate your scraps by color or something. What an idea!
