IceBlossom: You mentioned a hallway - it made me wonder if you could do this:
I have a quilting room upstairs in a Bonus Room....I discovered that when you walk toward the bathroom, the two walls before you walk into the bathroom narrow down and are perfect for an adjustable shower curtain rod. So, I hung a Fons and Porter Design wall on the rod with shower curtain rings. I pull it full width when I need to put my blocks on it. If I'm not using it, I push it back to one side side out of the way. This works very well for me - it's about the only option I have for a design wall because none of the walls in the bonus room are full height because of the design of the roof --- they all slant up after about 60 - 65 inches..... I hope all this makes sense....
