Brat - your stacks of scraps looks a lot like my fabric stacks. But I don't differentiate between big pieces and little pieces. If there's at least enough for a couple of squares it goes with its color pile, which may go up to several yards on some things. I usually start out with anywhere from 1-3 yards, a few as much as 5 or 6 yards. So I have several 6 ft shelves total, including fleece and drapery fabric. Upholstery fabric scraps are in a big tote. Must get it all better organized, someday when I'm not sewing. Lol!
