Using these Casey Cotton flat sheets is a breeze. Just put them on your king single bed like you would with any other sheet. For the best sleep, make sure the sheet is smooth and wrinkle - free. 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 cotton fabric. After washing, tumble dry on a low setting or hang them to dry. This will help maintain the softness and durability of the sheets. Also, don't iron them on a high temperature; a low - heat setting is best. With proper care, these sheets will serve you well for a long time.
