Using this Christmas curtain is a breeze. Just hang it up in your living room or bedroom with the free hooks provided. You'll immediately notice a reduction in noise and a cozier atmosphere. When it comes to maintenance, simply use a gentle detergent and cold water for hand - washing. Avoid using bleach as it may damage the 3D printing. Keep in mind that because of monitor settings, the color on your screen might not be exactly the same as the real curtain. Also, remember that each set comes with two panels, so if you need a specific width, calculate based on each panel being half of the total width given.
