Using these Casey Cotton Bed Sheets is a breeze. Just put the fitted sheet on your split king bed, making sure to align it with the tags for a perfect fit. Then, lay the flat sheet over the bed and tuck it in neatly. You can add the pillowcases to complete the look. When it comes to maintenance, you can machine - wash these sheets in cold water with a mild detergent. Avoid using bleach as it can damage the fabric. Tumble dry on a low setting to keep the sheets soft and wrinkle - free. With proper care, these sheets will last you a long time and continue to provide you with a comfortable sleep environment.
