Using your Casey Cotton Fitted Sheet and Pillowcase Combo is a breeze. Just put the fitted sheet on your double bed, making sure it fits snugly with the help of the tags. Then place the pillowcases on your pillows. For washing, you can use a regular laundry cycle with a gentle detergent. Don't use bleach as it might damage the cotton. After washing, tumble dry on a low - heat setting to keep the fabric soft. When it comes to ironing, use a medium - heat setting. This way, your bedding will stay in great shape for a long time, always providing you with a comfortable sleep environment.
