Using these Casey cotton sheet sets is a breeze. Just put them on your split king bed as you would with any regular sheets. The tags on the fitted sheet will help you get the orientation right. For the best results, wash them in cold or warm water on a gentle cycle. Avoid using harsh detergents or bleach as they can damage the high - quality cotton fabric. After washing, tumble dry on low heat. This will help maintain the softness and durability of the sheets. You can also iron them on a low - medium setting if you like a crisp look. With proper care, these sheets will last you a long time and keep you comfortable night after night.
