I have a suggestion that you may find helpful if you sew anything else besides quilts such as cushions or stuffed animals. I always save all my little scraps of fabric and pieces of thread in a bag or box and then when I've made something that needs stuffing I'll use them with the stuffing. Keeps it from being wasted and comes in handy if you happen to be out of stuffing. They could also work for crazy quilts if you have that much patience. I would use bigger pieces because ones that small would drive me crazy, but if it works for you, by all means give it a try. Anything that would save a few pennies here and there :)
