Using these Casey Cotton Sheet Sets is a breeze. Just put the flat sheet over your mattress and tuck it in neatly. Place the fitted sheet on the mattress, using the tags to make sure it's in the right position. The pillowcases can be slipped over your pillows easily. When it comes to washing, use a gentle cycle with mild detergent in warm water. Avoid using bleach as it can damage the fabric. After washing, tumble dry on a low setting to keep the sheets soft and in good shape. Iron on a medium - low heat if needed. These sheets are durable, but it's still a good idea to wash them regularly to keep them clean and fresh for a great night's sleep.
