These curtains are super easy to use. Just use the included hooks to hang them on your curtain rod or track. To keep them in good shape, when it's time to wash, separate the curtains into dark and light color batches. Machine wash them in cold water on a gentle cycle, and make sure the water temperature doesn't go above 30°C. There might be a size error of up to ±3 cm, but don't worry, it won't stop the curtains from fitting properly. Each set comes with two panels. If the size we tell you is 118 inches wide by 106 inches long, each panel will be 59 inches wide by 106 inches long. Also, because computer monitors vary, the color on your screen might be a bit different from the actual product.
