Using these curtains is a breeze. Just hang them up using the hook tops and they'll instantly spruce up your room. When it's time to clean, remember to separate them into dark and light color batches. You can machine wash them in cold water on a gentle cycle, but make sure the water temperature doesn't go over 30°C. Don't worry about the ±3 cm size error, it won't stop them from fitting perfectly. Each set comes with two panels, so arrange them as you like. Keep in mind that because of monitor differences, the color on your screen might be a bit different from the real product.
