Using these Casey Cotton Bed Sheets is easy. First, identify the tags on the fitted sheet to ensure it's placed correctly on your king single 60cm bed. Then, put on the pillowcases. For maintenance, you can wash them in a regular washing machine. Use a gentle detergent and set the machine to a normal cycle. Avoid using bleach as it can damage the fabric. After washing, tumble dry on a low - heat setting. This will help maintain the softness and durability of the sheets. If you notice any stains, treat them as soon as possible with a mild stain remover. With proper care, these sheets will serve you well for a long time.
