Using your 3D Christmas curtain is a piece of cake. Just install it on your window, and it'll instantly spruce up your room and keep the light and dust out. When it's time to clean, you have two options: machine - wash or hand - wash. If you choose to hand - wash, remember to use water below 90°F so you don't burn your hands. When taking the panels off for cleaning, do it gently to avoid hurting yourself. Keep in mind that because of monitor settings, the color on your screen might be a bit different from the real curtain. Each set comes with two panels. If the whole set is 118 inches wide and 106 inches long, each panel is 59 inches wide and 106 inches long. With proper care, this curtain will stay in great shape for a long time and keep looking as good as new.
