For purposes of laying out a quilting project, I want to use an approx 4' by 7' wall space. I have a large piece of thin fabric that is tacky on both sides. One side goes against the wall and stays there. On the other side, I place small blocks of fabric for a quilt, rearranging them until I've found a pleasing layout.
The tacky fabric needs a smooth wall surface. My painted and textured wallboard is not smooth enough. I could use additional spray glue, but I don't want to spray that on the wall, as it may be difficult to clean up when I want restore the wall to its original condition.
I think the solution is to mount another board on the wall, attached with appropriate anchors. I could put up gypsum board/drywall, but what other board type would be better? Something really smooth and thin would be best.
