Using these Casey Cotton sheets is a breeze. First, take the fitted sheet and use the tags on the sides to make sure it's placed correctly on your 40cm long single bed. Then, put the pillowcases on your pillows. For a great night's sleep, just lie back and enjoy the comfort. When it comes to maintenance, you can easily wash these sheets in your regular washing machine. Use a gentle cycle with mild detergent to keep the fabric in good condition. Avoid using bleach as it can damage the high - quality cotton. After washing, tumble dry on a low setting or hang them to dry. This way, your sheets will stay durable and comfortable for a long time.
