Getting ready to build shutters for my house, but don't know what kind of wood to use. Lowes sells wooden shutters on special order only that are made of western red cedar. That sounds durable, but isn't cedar going to have an open grain and knots that will show through the paint? I can buy WRC for 1/3 the cost of Lowes, so making my own interests me. I just want to make sure they will look nice, not be twisted, etc.. before I tackle this.
