Using these Casey Cotton Flat Sheets is a breeze. Just put them on your bed as you would with any other sheets. For the best results, make sure your mattress is clean before laying the sheets down. When it comes to washing, you can use a regular cycle in your washing machine with mild detergent. Avoid using bleach as it can damage the fabric. After washing, tumble dry on a low - heat setting. To keep the sheets in top condition, don't over - dry them. Once dry, you can iron them on a medium - heat setting if you like a crisp look. With proper care, these sheets will serve you well for a long time and continue to provide a comfortable sleep environment.
