I'm envious of all that room for a design wall - how wonderful! The only way I was able to fit one in my quilt room was to put up coat hooks over the closet (one on each side & one in the middle), and I sewed together flannel with a pocket at the top to slide a 1" x 2" long board in (left an opening in the center, so the hook could come through the flannel), and hung over the closet. Works perfectly and now have a design wall that's 7' tall by 8' wide. In your case I'd do the same, only make it larger. Or I'd do a frame out of 2"x2"s and sew white flannel together and staple onto the back of the frame to make it taut and attach to the wall or lean it from the floor against the wall.

I like that its removable - came in handy when I was spring cleaning, and needed to get to the closet to clean it out and re-organize. I don't have doors on the closet, so putting it back up was easy (and its still easy to get to the closet) and I have my design wall back up.
