I have 2 design walls ---- the one in my studio is a large foam insulation board that I bought at a home improvement store --- it is about 4 ft x 8 ft. covered it with fleece and propped against the wall - of course you could hang it, but I like to rearrange things. The quilt blocks stick to the fleece. The other is a plastic table cloth with the fuzzy cloth stuff on the back --- I pin it up with thumbtacks with the plastic side against the wall. (sometimes I use 2 if I need a big design area) ---- again, the blocks stick to the fuzzy stuff. My favorite of the 2 is the tablecloth. The tablecloths are cheap and you can take them down and put them away when not in use. I use the tablecloth when I am sewing in a room other than my studio. (hand sewing in front of the tv in the evenings with my DH)
