To use these curtains, simply hang them up using the free hooks provided in your living room or bedroom. They're great for blocking out light, reducing noise, and saving energy. When it comes to cleaning, you can gently machine - wash them in cold water. Make sure to follow the regular care instructions for polyester fabrics. Just keep in mind that there might be a small color difference between what you see on your screen and the real curtain because of monitor settings. Each set has two panels, so if you need a certain width, calculate based on each panel being half of the total set width.
