A cornice board is a four sided box usually made out of wood used to decorate a window. It is considered to be a form of hard window treatment. In effect it is a valance that can be covered with padding and fabric, it can be stained or painted and even covered with wallpaper.
You will find here a rather simple rectangular cornice with just a hint of detail on its face. Contrast piping is used at the seams on the larger cornice over the door wall. The fabric is 54 inches wide with the cornice being much wider. Factor in the small print, which is very difficult to match when seaming together, the piping became a great solution. Piping was then strategically used on the other cornices in the room. Vertical and horizontal blinds allow for sun control and privacy when needed.
