I saw a demo. They stitched an x across the square (probably to keep it from moving) and then sewed the squares together with a flannel backing and the seams showing on the front MissouriStarQuiltCo did a sample with charm size squares. It looked easy, but I also worked with some knobby ones and I did not do well. But these colors intrigued me. I probably need someone to talk me out of it.
