My whitewash stone fireplace in my living room goes from the floor to the vaulted ceiling. We installed tile on the bottom and around the fireplace to break up the stone. It is still too much stone from the top of fireplace to the ceiling. Can you recommend something to put over the fireplace that would break up the stone and add some color? It's hard to "nail" or screw anything into the stone, so I'm thinking of a painted design but don't know what to do. I'd like some color.
