Using this 3D curtain is a breeze. Just hang the two panels up in your desired window. It'll immediately start blocking sunlight and adding a decorative touch to your room. When it's time to clean, you can either use a washing machine or wash it by hand. But if you're hand - washing, make sure the water temperature is below 90℉ so you don't burn your hands. Also, when taking the curtains off for washing, do it gently to avoid any injuries. Remember, each set comes with two panels. If the total width is 118 inches and the length is 106 inches, each panel is 59 inches wide and 106 inches long. And don't be surprised if the color on your screen looks a bit different from the real curtain because of monitor settings. This curtain is made of polyester, so it won't pill, fade, or come apart easily. Just follow these simple steps, and your curtain will last a long time.
