I've been wondering how I could make me a design wall here in my small house. I finally figured that I could use the wooden valences over all the windows in the house. In the sewing room I can make (from wire hangers maybe) some curved wires that will hook over the valences, and hang down long enough to wrap around a long, thin piece of (balsa?) wood. I can tack flannel over it and when I'm finished, take it down, wind it up and stick it in the closet.
The only thing is, I have no idea of how strong the wood valance is, but my 12 pound cat has traveled over the one in the front room for years and it's not even bent yet.
Tried pinning stuff to the drapes and the pin holes still show up against the bright sun light.
