This is one of the walls in our living room. The only wall, in fact, that we are able to have any pictures on, so I need to take advantage of it. I rarely change these pictures out, but do move them around a lot to accommodate seasonal items. It's really nice to be able to do that without poking a bunch of holes in the walls.
These are actually 6 shelves. 2 sets of 3, put side by side. The pictures are layered and I've only had one fall in over 3 years of being up there...and that could have been due to my
monkey's children climbing around on the stairwell rail (which is on the other side of that wall.)
