About This Window Treatment Tailored Cornice Board Valance features clean lines with an emphasis on simplicity. This valance is equally at home in traditional or contemporary settings, bringing softness to windows while hiding the hardware components of blinds and shades. Create your valance in one of our solid color fabrics, or add some pattern to your decor with Subtle Stripe, Classic Stripe or Country Club fabrics. Our fabric cornice boards are hand-made on an all-wood frame and include upholstery fabric fill, self cording for a finished look, and a matching dust cap cover. Tailored valances are 16" in drop length. Note: Measure exact width of window and round to the nearest ½”. Allow an additional 2” to compensate for cornice sides.
