Window treatments can set the tone for a room by adding natural light or taking it away, creating a level of formality, or keeping things casual. To choose the right window treatments for your home, consider style, fabric, color, and effect.
Decide if you want your treatments to blend or offer a contrast. The type of material can influence the style of décor and affect room temperature. For example, heavy, dark-velvet curtains tend to read more traditional or masculine, but they are effective for insulating a room. Light linen or silk can brighten a room and make it feel more airy. They also help keep the room cool.
Your window treatment can influence the perception of the proportion of the window itself. The way you hang your window treatments can also trick the eye into thinking the window has different dimensions.
