I could do this...couldn't I? Print board pictures and collage them on the wall like this. Love the idea.
.narrow shelving is a good way to have a gallery wall where you want to change out the photos or prints. No new holes made and plenty room for many prints. If you put a plate groove in the shelf, or add a small molding to hold the frames from sliding, then any vibration felt in the house won't have the frames falling or moving. You can make a larger area for large prints and a smaller area between two shelves for smaller frames.
