brad nails to attach this to the wall and using my level to make sure it's good. I'm doing a double box feature, so I'm going to use some scrap wood so I get even spacing and then I'm going to do the same thing. Pow. Pow. Pow. Then you got to fill all the nail holes with wood filler and then you're going to come back and caulk all the places where the board meets the wall. Once that's all good to go, you're going to come back and paint it any color you want. That's how easy it is to transform that room to this room.
