Using this curtain is super easy. Just hang it up using the convenient hook - top design. To keep it in good condition, when you wash it, separate it into dark and light color batches. You can machine wash it in cold water on a gentle cycle, but make sure the water temperature doesn't go over 30°C. Don't worry about the size too much as the maximum permissible size error of ±3 cm won't affect how it fits. Also, keep in mind that because of differences in computer monitors, the color on your screen might be a bit different from the real curtain. Each set has two panels, so you can set them up as you like to decorate your room and block the sunlight.
