Using these Casey cotton fitted sheets is a breeze. Just place the sheet on your double bed with the 60cm depth and align it properly, using the tags as a guide. For a good night's sleep, make sure the sheet is smoothly spread. When it comes to cleaning, you can wash them in a regular washing machine. Use a mild detergent to keep the fabric in top condition. Avoid using bleach as it may damage the cotton. After washing, tumble dry on a low - heat setting. These sheets are quite durable, but to make them last even longer, don't over - stretch them when putting them on the bed. With proper care, you'll enjoy these comfortable sheets for a long time.
