Using your Casey Cotton Fitted Sheet & Pillowcase Combo is a piece of cake. First, place the fitted sheet on your queen - sized bed. The tags on the sides will help you make sure it's in the right position. Then, put the pillowcases on your pillows. For the 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 fabric. After washing, tumble dry on low heat. This will keep the cotton soft and the sheet's shape intact. With proper care, these sheets will serve you well for a long time.
