Outside Mount with a Return

The flat valance has a 3-3/4-inch rod pocket, so it can work on either a lockseam or a 2-1/2-inch wide pocket (also known as Dauphine, or continental) rod. The available rods will typically allow you to choose any desired return from 2 inches to 8 inches, as needed.
Follow the same measuring instructions for "Outside Mount with No Return" and simply add the rod return twice to the measurement.
EXAMPLE: Window width is 38 inches, including the window trim. Adding an extra 1 inch makes it 39 inches. If the rod has a 5-inch return, add an extra 10 inches. In total, the valance width to order in this case is 49 inches.
