I second the magnetic paint. My wife used some at our other house on a closet door. Then painted over it. Refigerator magnets and little words on the pliable magnetic backing work great on it. The kids did all sorts of things with it. It's not cheap, but with being able to paint over it, it works very well. Not sure how well it would do on a textured surface. Might need to mud and sand that part of the wall smooth, then paint the magnetic stuff, then paint over it. Jim.

At a minimum, I'm Pentatoxic...but most likely, I'm a Pentaholic. There seems to be no known cure. Pentatonix, winners of The Sing Off, season 3
