I wonder if you could use one of those room dividers that would be freestanding. Then you could mount your cork board or styrofoam covered with felt on the back side for a display board while using the other side for storage? Just as thought. Or even build a room divider (on wheels if you like) that is flat on both sides for where you could have 2 display boards & be working on more than one project at a time? Something similar to the old chalkboards that were able to be wheeled into a classroom. Ok...that's my contribution of ideas..Hope you find one you like!!
