Using these Casey Cotton Fitted Sheet and Pillowcase Combos is a breeze. Just put the fitted sheet on your single 60cm bed. The tags on the sides will help you place it correctly. Then, slip your pillows into the pillowcases. For a good night's sleep, make sure the sheets are smooth. When it's time to clean them, you can wash them in a regular washing machine. Use a gentle detergent and a normal cycle. Avoid using bleach as it may damage the high - quality cotton. After washing, tumble dry on a low - heat setting or hang them to dry. This will help maintain their durability and keep them looking great for a long time.
