My DH created a Design wall for me out of PVC pipe. I have 2 pieces I can put side by side for an 8' wide 6' high design wall. I used flannel and some old fabric to create slip covers I just slide over them like a pillow case. When they get dirty I'll throw them in the washer and a little shrinkage will make them fit even better. We are going to be vendors at 2 quilt shows this fall and they will do double duty as backdrops for DH's featherweights and 301s.
