I often sew these scraps together randomly. But remember, random does not mean that none of the same will be touching. I work very hard to not consciously choose fabrics with the exception that I won't purposely use the same two next to each other. Wish I could post a pic but the camera and I are in different locations! I've done many random piecings and it never fails that there are two of the same pieces next to each other by the end! Believe it or not, this process works and makes really attractive quilts.
