A custom scarf treatment is a great way to treat a triple arched window like this one and is easy on the budget. I designed this scarf treatment using decorative crown hardware with hold backs and fabric knots. The embroidered fabric has a hidden seam in the center to turn the fabric pattern so that the pattern looks the same on both sides. I used a standard lining on the back for a clean look from the outside. The lining protects the fabric and gives the treatment body.
