I have a lovely design wall at one end of the room...3 light blue insulation boards nailed to the wall and covered with backing flannel, 6 by 8 feet wide. However, one design wall is not always enough, lol. I made a folding screen with three panels cut down some. I taped two boards together on one side and the second seam was taped from the other side, so the screeen could be folded like an accordian when not in use. I covered this one with an old queensized flannel bed sheet. Didn't cost much. The beauty is that you can make it any size you want.
