Using your Casey Cotton Fitted Sheet and Pillowcase Combo is a breeze. First, find the tags on the fitted sheet to make sure you put it on the bed correctly. Then, just slide the pillowcases over your pillows. For the best results, wash these sheets in cold or warm water. Avoid using harsh detergents as they might damage the fabric. You can tumble dry on a low setting. Once dry, they're ready to go back on your bed. These sheets are durable, but try not to over - stretch them when putting them on or taking them off the bed. With proper care, they'll keep you comfortable for a long time.
