You can use these curtains in your bedroom as a blackout curtain to keep the light out and ensure privacy. Or hang them in the living room as a beautiful window decoration. When it's time to wash, remember to separate them into dark and light color batches. The size error of ±3 cm won't cause any fitting problems, so don't worry about that. Wash them in cold water on a gentle cycle, and make sure the water temperature doesn't go above 30°C. Each set has two panels, so if the overall size is 118 inches wide by 106 inches long, each panel is 59 inches wide by 106 inches long. Also, keep in mind that there might be some color differences between what you see on your screen and the actual product because of monitor variations.
