– is designed to use a 40 2 1/2″ strip pack, one that has 2 each of 20 prints. The math doesn’t work if there isn’t 2 each, because 2 strips makes 3 blocks. It also works well in scraps,–4 2 1/2″ x 6 1/2″ plus a contrast in the center. This quilt here is from our community service group. It is made from decades old little prints that have a richness to them when they are all cut up and placed together in a quilt.
