I have to have a design wall. I use poly low loft batting as a cover. A whole quilt top will stay put on that. DH made a frame around two 8 x 4 sheets of insulation boards. You can never have a too big design wall. I stapled the batting on the boards inside the frame. When I go to retreats or sew days. I take one of the folding cardboard pattern boards with a piece of batting to pin to it. Works great and it stands up.
