I'm sure as heck no expert on this type of thing, but I think that'd be an awful mess to put up and then take down when you got tired of it!!
Years ago I read something in a decorating magazine about fabric; this article suggested making a frame the size of the wall, and then attaching the fabric to the frame, then putting it against the wall......if it's a large wall, and impractical to have a frame so large, just do it by halves......cannot recall what they suggested to anchor the wood to the wall, but it'd sure be lots more practical than fabric starch!!
Sorry I can't provide more details, but this will hopefully give you something to think about!! good luck and have fun with it!!!!!!!!
