For an 'extra' design wall, I covered the back of the door in my sewing room with felt (just happened to have some left over from a project). I stapled it to the top of the door so as not to mess up the door face and since my felt was not long enough to reach the bottom, I just taped it to keep it from flopping around. You can re-stretch and re-tape when necessary. Its a bit narrow but doesn't take up room or have to be stored! Smiles Mary Quilter
