Using these Casey cotton sheets is a breeze. First, just lay the flat sheet on your bed, smooth it out, and tuck in the edges. Then, find the fitted sheet. The tags on the sides will help you figure out which side goes where. Simply stretch the fitted sheet over the corners of your super king - sized bed. For pillowcases, just slip your pillows inside. When it comes to washing, you can use a regular cycle in your washing machine with a mild detergent. Avoid using bleach as it can damage the cotton fabric. After washing, tumble dry on a low - heat setting to keep the sheets soft and fluffy. These sheets are quite durable, but it's still a good idea to check for any loose threads or signs of wear every now and then. If you find any, you can easily mend them with a needle and thread. With proper care, these sheets will serve you well for a long time.
