These 3D blackout curtains are a great addition to your room. To install them, simply hang the panels on your curtain rod. When it's time to clean, you can either use a washing machine or wash them by hand. If you choose to hand - wash, make sure the water temperature is below 90°F to protect your hands. When taking the curtains off for washing, do it gently to avoid any injury. Remember, each set comes with two panels. If the size says 118 inches wide by 106 inches long, each panel is 59 inches wide. Also, don't be surprised if the color on your screen looks a bit different from the actual curtains because of monitor settings. With proper care, these curtains will last you a long time and keep your room looking great.
