Using your 3D blackout curtain is easy. Just hang it up in your living room or bedroom with the free hooks provided. The curtain is great for blocking out light, reducing noise, and saving energy. When it comes to maintenance, you can gently vacuum it to remove dust. If it gets dirty, you can machine - wash it on a gentle cycle with cold water. Remember, because of different monitor settings, the color you see on the screen might be a bit different from the actual curtain. Each set has two panels, and if the set size is 118 inches wide by 106 inches long, each panel is 59 inches wide by 106 inches long.
