I got a piece of the thin plywood. It's not actually plywood but the material that they use on the end of cabinets. The hardware store will cut it to size. I took it home and covered it with batting and muslin. Orginally it was a small design wall; only about 2 ft wide and 50 long. Now I take it and put in on my cutting table when I need to cut large fabric. Tell your husband the ones that store in the wall is only good for the little blocks; no way it is good for anything larger; I have one. Good luck
