Q:
My windows will require blinds mounted externally. If I buy a product that does not have a cornice option what covers the top of the fixture?A:

Inside Mount "Cornice Style" Valance vs Standard Crown Valance
A cornice valance simply put is made from the same material as our standard valances. A standard valance will fit within the window frame with the blinds on inside mount. With the cornice style valance, the valance will be about 2 inches wider than the window frame and have returns at ninety degrees to create a cornice like look to the valance.
