To use this sheet set, simply put the fitted sheet on your single bed first, making sure it fits snugly at the corners. Then spread the flat sheet over the bed and tuck it in neatly. The pillowcases can be slipped over your pillows. When it comes to cleaning, it's best to wash these cotton sheets in cold water on a gentle cycle. Avoid using harsh detergents or bleach, as they can damage the fabric. After washing, tumble dry on a low - heat setting to maintain the softness. Also, store the sheet set in a cool, dry place when not in use to keep it in good condition.
