Thanks for the idea!! Should I make these out of wood? And do you think I could use two cleats, one at the top and one at the bottom? That might cause the frame to look odd, because I think this will cause it to look like it's floating on the wall. However, I think it would be more secure and we'd be able to push against it while cleaning it. Maybe I could even space them evenly along the back of the mirror so they could also be used to hold the mirror in the frame and also provide the support/backing needed to push against it for cleaning (not sure that is going to be safe though)... Thanks Again!!
