Using your new 3D blackout curtain is a breeze. First, install it on your window using the appropriate hardware. The curtain is great for blocking out light and dust, and also adds a beautiful touch to your room. When it's time to clean, you can either use a machine or wash it by hand. If you choose to hand - wash, make sure the water temperature is below 90℉ to protect your hands. When removing the curtain for washing, do it gently to avoid any injuries. Remember, each set comes with two panels. If the size mentioned is 118 inches wide by 106 inches long, each panel is 59 inches wide by 106 inches long. Also, keep in mind that there might be a small color difference between what you see on your screen and the actual curtain due to monitor settings. With proper care, this curtain will serve you well for a long time as it doesn't pill, fade, or come apart at the seams.
