As their name implies, these valance curtains are made of lace or sheer, often translucent, fabrics. This is the go-to valance category if you want a full-coverage window treatment that lets “the sun shine in.” Lace, of course, can be intricate or simple in its pattern—but it is always elegant. Want some color added to your new light-filtering valance? Sheer valances are for you. Often in pastels or jewel-tones, “sheers” offer a soft mood to any room.
