A fabric covered wood cornice mounted over draperies or blinds neatly frames a window and adds architectural interest to a room.
A cornice is practical also – it hides the heading and the hardware at the top of the window treatments, keeps out sunlight from around the top and edges and helps block out drafts. You make a scalloped cornice in much the same way that you make a straight cornice first making a template and drawing that design on the board. You then cut the face board on the marked lines. A scalloped cornice will add softness and more interest especially if it is a small window as shown here.
