Using your 3D polyester window drape is a breeze. Just install it on your window as you would with any regular curtain. To clean it, you have two options: machine - wash or hand - wash. If you choose hand - wash, remember to use water below 90℉. When it's time to take the curtains off for cleaning, do it gently to avoid hurting yourself. Each set comes with two panels, so if you ordered a size of 118 inches wide x 106 inches long, know that each panel is 59 inches wide x 106 inches long. Also, don't be surprised if the color on your screen is a bit different from the actual curtain due to monitor settings. With proper care, this curtain will serve you well for a long time, thanks to its no - pilling, no - fading, and no - off - lining features.
