This Tyvek scallop window valance by Ellis Curtains is available in a small diamond pattern in rust at The Curtain Shop. It's a fully lined American-made 100 percent cotton valance in a 70-inch width and 15-inch length designed to fit a single standard window.
To add more fullness, purchase two valances. The 2-inch header creates subtle ruffling at the top. A 3-inch rod pocket will accommodate a 2 1/2-inch diameter curtain rod. The scalloped bottom edge is self-corded.
