Using these Casey Cotton Fitted Sheets is a piece of cake. First, simply lay the sheet over your king single bed, making sure the tags are in the right position to ensure a perfect fit. Tuck the sheet under the mattress snugly. When it comes to washing, you can use your regular laundry detergent. These sheets are easy to wash, but it's best to use a gentle cycle to maintain their quality. You can dry them in the dryer on a low - heat setting or hang them to dry. Avoid using harsh chemicals or bleach as this might damage the fabric. With proper care, these sheets will stay in great condition and keep you comfortable for a long time.
