Using your Casey Cotton Fitted Sheet & Pillowcase Combo is a breeze. First, find the tags on the fitted sheet to make sure it's placed correctly on your long single 50cm bed. Then, simply put on the pillowcases. For a good night's sleep, pair them with your favorite pillows. When it comes to washing, use a gentle cycle with mild detergent. This will help maintain the fabric's quality. Avoid using bleach as it can damage the cotton. After washing, tumble dry on low heat. With proper care, these sheets will keep you comfortable for a long time.
