Using these Casey Cotton Flat Sheets is easy. Just put them on your king single bed, smooth them out, and you're ready for a great night's sleep. When it comes to washing, you can use your regular laundry detergent and wash them in a normal cycle. Avoid using bleach as it might damage the fabric. To keep them looking their best, dry them on a low - heat setting. If you want to iron them, use a medium - heat setting. These sheets are durable, but try not to tug or pull them too hard when making the bed to prevent any unnecessary wear and tear.
