An arch adds classical beauty to your room. The simple geometry enhances any style. However, an arched window can be tricky. Leaving the glass bare is rarely the best window treatment, even with tricky arches. Instead, select a window treatment that enhances the beauty of the glass arch.
The most obvious option for draping an arched window is to follow the curve. You can have rods customized to follow the curve or select flexible rods and tack them accordingly. From there, any drapery style works, though filmy curtain panels create their own soft arcs of fabric. The key to making the drapes fall well is securing them up top with locking rings. Utilize tie-backs to adjust the panels for light and privacy.
Using fabric to echo the arc is a complementary style of window treatment. Tied back panels offer gentle side arcs. However, another option is to hang London shades. As Better Homes and Gardens describes them, London shades are like a cross between Roman and balloon shades. They feature the flat upper panels of Roman shades, but two gatherings at the bottom that create an arc. You could hang these from a curved rod or affix them straight halfway down the window.
Another option for dressing arched windows is with full-length drapes affixed to a rod above the arc. This style of window treatment allows you to customize the draperies to the room style. For example, if you have modern décor, install a chrome rod and hang straight panels. The chrome nods to the industrial roots of modern style, while straight panels offers the geometry characteristic of such décor. Alternatively, install an intricately decorated rod with luxurious drapes for a more traditional effect.
If your windows don't require full draperies, consider customized valances. A valance covers only the top portion of the window, offering a little shade and also enhancing the shape of the arc. The valances must be custom made to snugly fit the top of the arc. Select a fabric that complements the rest of your décor, but avoid patterns that can draw attention away from the arcs.
Another option for windows that don't require full draperies is to hang treatments halfway down. Most arched windows feature an obvious transitional space moving from curved to straight. Install a rod at this transition, and hang any kind of treatment you like. Café curtains are naturally made for just half the window, but standard panels work well, too. If you'd like to create another arc with your draperies, hang swags from the rod.
