A scarf valance of the same fabric as the draperies is an effective way to add richness to a simple drapery treatment. Using a different color of the same fabric heightens the effect with contrast. If you choose to use a different color, consider the appearance you are aiming for. A color that has the same value (lightness and darkness) and intensity (brightness and dullness) as the drapery fabric will provide a subtle contrast. A color that is significantly different in value and intensity will provide contrast that is more dramatic.
Instead of using the exact same drapery fabric, you can choose the same color fabric in a different texture for the scarf valance. For example, if your draperies are sage green voile, you can create a valance from sage green velvet. Alternatively, sage green velvet draperies could be enhanced with a sage green voile scarf valance. The contrasting texture adds interest and sparkle to a basic drapery treatment.
A scarf valance can provide both an accent color and texture to the window drapes. The valance offers an opportunity to make the window a focal point in the room by presenting contrasting color, texture or pattern. These design elements will frame the window view during daylight hours, and relieve the monotonous effect of a draped expanse at night.
Scarf valances are usually constructed from sheer and lightweight fabrics. When the scarf valance is pleated, a lining becomes essential, because the “wrong” side becomes visible between pleats. The lining fabric offers additional opportunities for variety in texture and color. For example, you might choose lace as a lining, or a coordinating print. Other enhancements include adding trim such as braid or fringe at the edge of the valance, and angling the fabric ends on each side for a neat, tailored effect.
