Really great way to use circles. I was curious how it would work with squares. Ended up with a combo, in my opinion, that would be great for making light weight quilts. Take 3 squares, middle one could be light weight batting or cloth. It would be your choice. Since the frayed edge quilts are so popular now, leave bottom right side down and top square right side up. Sandwich the three and sew together like a regular square quilt piece. Again, "Quilt as you go" squares.
