Using this curtain is easy. Just hang it up in your living room or bedroom to enjoy its beautiful 3D pattern and sun - blocking effect. When it's time to clean, you can either use a washing machine or wash it by hand. Remember to take it off gently to avoid hurting yourself. Use water below 90℉ to protect your hands. Each set comes with two panels, so make sure you know the size of each panel when you're measuring for your window. Also, don't be surprised if the color on your screen looks a bit different from the real curtain because of monitor settings. To keep it in good condition, avoid harsh chemicals during washing, and it will stay free from pilling, fading, and off - lining for a long time.
