We just bought our first house and it has this horrid lava rock fireplace! The old owners added a Schrader fireplace insert. We'd like to take that out and use the original fireplace cut out. The problem is, we can't figure out what to do with the design. We can't afford all natural rock so we were thinking of doing part natural rock and the other part would be turned into either a wall or we'd use plywood with trim all around. ANY OTHER IDEAS? We are really stuck on what would look good. Thanks for ANY help!
