I prefer a controlled scrappy too. There were several times on "Simply Quilts" when a guest quilter would put the scraps in a paper bag, then pull out one piece at a time, and no matter what came out they used. When I tried it I got similar colors together and it was just bad, so ended up taking the pieces apart. Maybe if you separate the colors, then put the separate colors in separate bags and then pull them out from there. The other way just did not work for me.
