I save fat qtrs, chunks (about 10" flats), 5" squares, 2 1/2" squares, 2 -2.5" strips, and strings 3/4" or wider. I once made a beautiful crumb quilt out of fabric I cut for a king size winding ways that was a disaster . It is a beauty, but I don't save crumbs. And I dont have any yardage except muslin. My backings and bindings are even made out of these pieces. They are organized because they are my only source of fabric.
