I just paid postage from a fellow quilter on this website from Ohio- got a great box of crumbs. I make lots of crumb blocks with little pieces. I have sorted some of the goodies in the box and the too small stuff goes in a bag for the dog beds. Yes you need seams in crumb blocks, and I am careful. Some of my 4" blocks have over 50 pieces.....there is no quilt police with these. My quilting buddies think I'm nuts for wasting time making fabric- BUT they sure love seeing what is created from their castoffs. I appreciate them--I also have a pretty hefty stash which I pet on occasion-but I'd rather play with crumbs and strings.
