Karen: here's a pic of my cheap, but effective design wall. I used CommandPerformance hooks, a cafe curtain rod with extension, and a $5.00 double bed size flannel sheet from Walmart. I folded the top of the sheet over the rod and pinned it so I can make it longer if needed. My space is small so the sheet's folded in half (about 48" wide folded.) It's basic, but works for me. I made the OBW blocks and they looked fine on the work table but once they were up on the wall, I could tell there was no contrast. I'd love to have a larger and more permanent design wall but space is too small.
