What is a one-sentence summary of the following article?
For a small window, you may only need one curtain to cover the whole thing. However, if you're covering a larger window, you may want two curtains that part in the middle. For an extra-large window, you may want to consider multiple curtain panels. When you're taking your widthwise measurements, be sure to divide the final number by the number of panels you want before cutting your fabric. For instance, if you need 30 feet (9.1m) to cover a window and you want three separate panels, each panel must be 10 feet (3m) wide (30 3 = 10). You have a lot of choice when it comes to choosing fabrics for curtains, but you should take into account what kind of effect you want to achieve. For instance: To add a bit of privacy without blocking out too much light, choose a lighter weight material that has some transparency, such as voile or linen. To block out light or drafts, choose a heavier material, such as velvet, corduroy, tapestry, or damask. For an ultra-lightweight curtain in areas where you don't need privacy, try lace, chiffon, or organza.
