I quilted with our Sioux friends when we lived out in s.d. and they had the 4 boards and the c clamps. our quilts turned out very well, and we rolled them as we quilted each section. We wrapped the 4 boards with strips of fabric, then used thumb tacks all around to hold the layers together as we quilted. rolling them onto the first board as we went.NO wrinkles on backing, and the tops held so beautifully.
