I love crumbs... for me, anything bigger than an inch is a crumb. I want to be able to see it when I sew it into the block. I have a friend from guild who gives me hers, and I am always looking for more. For me, to toss it in the trash is wasteful. I do not dedicate time to sew crumbs, but when I want to sew and not think too hard, I sew crumbs
