I have a stash of precuts too. A lot of them have come from Missouri Quilts' Deal of the Day or clearance Craftsy kits (I never intend to make the kit, but the precuts are much cheaper this way - recently got 2 jelly rolls and 1.5 yards + a pattern for $17). I've been considering breaking up the precuts and sorting by color. I'm a "wing-it" type of quilter and rarely use the prescribed colors of any pattern.
