Very creative....I too, am about out of wall space as I took my signs down from hanging on the rafters and put them on the walls so they were more visible. I have been using magnets that you can buy at any hardware store so yo don't have to try to hit studs where the holes in the signs are. But, for lighter signs I am considering to start putting them flush to the ceiling. the "60 and 90 pound" magnets really hold well.
