Using your Casey cotton fitted sheet and pillowcase combo is a breeze. First, find the tags on the fitted sheet to make sure it's the right way around, then place it on your long single 50cm bed. Next, slip your pillows into the pillowcases. For a good night's sleep, just get in and enjoy the comfort. When it comes to maintenance, you can wash these sheets in your regular washing machine. Use a gentle detergent and a normal cycle. They're durable, so don't worry about them wearing out easily with multiple washes. However, avoid using bleach as it might damage the fabric. After washing, tumble dry on a low setting or hang them to dry. This will help keep the sheets in great condition for a long time.
