Using these Casey Cotton Fitted Sheets is a breeze. Just put the sheet on your queen - sized bed with a 40cm depth, and use the tags on each side to make sure it's correctly placed. For washing, you can use a regular cycle in your washing machine. Use a mild detergent to keep the fabric in great condition. Avoid using bleach as it can damage the cotton. After washing, tumble dry on a low - heat setting. This will help maintain the softness and durability of the sheets. You can iron the sheets on a medium - heat setting if you want them to look extra crisp. These sheets are made to last, so with proper care, you'll enjoy their comfort for a long time.
