Playing with squares – 1”, 2” and 4” – helps you to use up your tiniest scraps. I had a stash of what looked like useless little bits and I cut them down to 1 ½” squares. (I made the painful decision to throw out anything smaller). I sorted them into two piles – light and dark (reds in the dark pile) and anytime I was sewing I would sew together a few light/dark pairs, press the seam to the darker side and put them away. In the end I had so many pairs made that it was time to figure out a use for them.
