I love my temporary "design wall" that I got on clearance. It's from Fons & Porter and is basically flannel with holes for hooks on the top. I use Command hooks and just pop it up when I'm working on a large quilt. (Normally my thread spool s are hanging there).
I got it for $6.00 because JoAnn was getting rid of it. They still sell them however-not as cheaply but you could use a coupon. I love the fact that I can fold it and throw it in a drawer when not in use.
