I must have been interested in this double wedding ring quilt for a while. In digging through my supplies, I found a book by Mary Henderson & Anne Dease. There method is to use arcs of fusible interfacing and sew your pieced arcs to them. Then turn them right side out and press onto a 12 x 12 square. The corner pieces are then done in a flip and sew method to cover the square piece. You can order the interfacing with the printed design from quiltsmart.com. I think I am going to try this one and the one from Quilters Cache and see if I can accomplish them.
