Using these Casey Cotton Sheet Sets is super easy. First, unfold the flat sheet and spread it over your mattress. Then, place the fitted sheet on the mattress, using the tags to make sure it's in the right position. Put the pillowcases on your pillows. To keep your sheets in great shape, machine - wash them in cold or warm water on a gentle cycle. Use a mild detergent. Avoid using bleach as it can damage the fabric. After washing, tumble - dry on low heat or hang them to dry. This will help maintain their softness and durability. When not in use, store the sheets in a cool, dry place, preferably in a breathable cotton storage bag.
