Oooh that's a good idea! That would eliminate a lot of nail holes in the walls. I wonder what height I would do that at?
I've thought about using some gallery hanging rods at the top of the long wall so that I could hang the paintings from the dangling wires. That way I could change the paintings out often and adjust for different heights. We're using that in our gallery in Laguna Beach for the window displays and it's working well. Decisions, decisions. ; ) Thanks for the new idea!
