Using your 3D polyester curtain is easy. Just hang it up using the free hooks provided. It will not only add a decorative touch to your room but also insulate against sound, heat, and keep dust out. When it's time to clean, separate it into dark and light color batches to avoid color bleeding. Then, you can machine - wash it in cold water on a gentle cycle. Make sure the water temperature doesn't go above 30°C. Keep in mind that there may be a size error of up to ±3 cm, but this won't affect how it fits. Also, each set comes with two panels. If you ordered a size of 118 inches wide by 106 inches long, each panel will be 59 inches wide by 106 inches long. Don't be worried if the color on your screen looks a bit different from the actual curtain, as this can happen due to monitor differences.
