Using your Casey Cotton Fitted Sheet and Pillowcase Combo is a breeze. First, put the fitted sheet on your king - single bed. The tags on each side will help you make sure it's the right way around. Then, slide your pillows into the pillowcases. For best results, wash these sheets in cold or warm water on a gentle cycle. You can use a mild detergent. Avoid using bleach as it might damage the cotton. Tumble dry on low heat to keep the fabric soft. After drying, you can iron them on a low - medium setting if you want a crisp look. With proper care, these sheets will stay in great condition for a long time and keep you comfortable night after night.
