In a room where the natural light comes in via a pair of French doors separated by an interfenestration, install ornate curtain rods almost to the ceiling and with a single, heavy curtain panel on each. The curtains are long enough for the fabric to pool a bit on the floor and hold with tiebacks.
Window dressing isn't the only use for curtains. Curtains can be used to separate one area of the home from another. A parlor, for example, can be separated from a sitting area by elegant pleated curtains that hang from a valance. The same treatment is seen on a window in the parlor, while the color of the curtains reflects the colors of the armchairs in the sitting area.
Curtains are also used for outdoor spaces. Hang white curtains made of light fabric on a deck or a patio. Make sure that the fabric is easy to clean and made for outdoor use.
Some windows are more challenging to dress than others, such as a row of small windows with swing arm rods in a bedroom. Curtains cut to size and mounted on the arms are a sure fit. Use curtains attached to runners on the ceiling to provide privacy for a bunk bed. They are especially useful if the sleeping area serves as a living area during the day.
