On my last quilt, I just tacked my quilt backing to a bedroom wall; sprayed it well then smoothed on the batting, sprayed it well and then smoothed on the guilt top. It worked really well. But next time, I will definetely remember to apply some newspaper around the wall and the floor. It was easy to clean up, but would have been much simpler to just prepare the area first. So, I would think that a design wall would work also. Just remember to put something around it or the basting spray will be on your design board fabric.
