I have two 4x8 sheets which stand side by side against one wall (less the 6" I cut off the height of each of them, since I have 8-foot ceilings.) My "sewing room" is a bedroom (with a Murphy bed), so when I have "special company", I can easily carry the boards to the storage room if I want them out of the room. I also have a long drapery rod with clamps on rings high on that wall, and I can hang a quilt for display to brighten the room for company. Works for me--can't imagine life now without a design wall. You'll love having one, too, no matter whether you decide to permanently mount them to the wall or not.
