Using these Casey cotton flat sheets is a breeze. Just put them on your double bed like you would with any regular sheet. To ensure a good night's 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 may damage the fabric. After washing, tumble dry on a low - heat setting or hang them to dry. This will help maintain the softness and durability of the sheets. With proper care, these sheets will serve you well for a long time.
