Hanging window treatments is one of the simplest décorating projects you can undertake. But the payoff from dressing up an ordinary window with a little color and texture can be startling.

Perhaps the most challenging part of the job is choosing hardware of the appropriate size and style. That's why it is crucial to measure the window before buying materials. Curtains typically look best when they span just beyond the window casing. As for length, they can hang to the window sill or almost to the floor-or a point somewhere in between. Take your measurements to Lowe's-they'll help you select from among a range of ready-made window treatments and make sure you go home with the suitable hardware.
