Using these Casey Cotton fitted sheets is a breeze. Just place them on your 60cm Queen Bed, making sure to align the tags correctly for a proper fit. For washing, you can use your regular laundry detergent and wash them in cold or warm water on a gentle cycle. Avoid using bleach as it can damage the fabric. After washing, tumble dry on low heat. These sheets are very durable, but to keep them in great condition, don't over - dry them. Also, when ironing, use a low - heat setting if needed. With proper care, these sheets will serve you well for a long time.
