If I can't cut a leftover piece into 2 1/2 x 20 inch strips or 3 1/2 x 6 1/2 bricks, then I consider it scrap. The last two years I carefully cut anything less than 2 1/2 into strips to use in a string quilt. I muddled through making string half square triangles paired with a neutral until I had half enough squares for a comfort quilt. I decided I hated sewing string quilts, packed up the strips, the blocks, the neutral and the muslin and called a friend in our quilt guild to come get it. She loved it!!
