Using these fitted sheets is a piece of cake. Just place the sheet over your Super King bed and make sure it fits snugly. The tags on each side will help you get the orientation right. When it comes to washing, you can toss them in the washing machine on a normal cycle. Use a mild detergent to keep the fabric in good shape. Avoid using bleach as it can damage the cotton. After washing, tumble dry on a low setting or hang them to dry. This will help maintain their durability. If you notice any loose threads, simply trim them with a pair of scissors. With proper care, these sheets will serve you well for a long time.
