I love my design board. I made out of 2 4' X 8' sheets of 1 1/2 inch foam board, from lumber yard. My husband cut them both down to 6 1/2' in height, as my basement ceiling is only 7' high. I taped them together on one side with package striping tape. Then I covered them with a large piece of flannel and pinned the flannel to the foam board (this is construction foam insulation). Where I taped the two pieces together, I can fold them in half, thus taking up 4' of wall space, except when I am using it. I can also stand it in the middle of the room, as when I open it, I leave in the a very shallow V, and it will stand alone by itself. I really love it.
