Using these Casey Cotton Fitted Sheets is a breeze. Just place the sheet over your long single bed with the 40cm depth, aligning the corners and using the tags to ensure it's in the right position. When it comes to washing, you can use a regular cycle with mild detergent. Avoid using bleach as it can damage the high - quality cotton fabric. After washing, tumble dry on a low - heat setting to keep the sheet's shape and softness. These sheets are built to last, but to maintain their durability, try not to overload the washing machine. With proper care, you'll enjoy the comfort and luxury of these sheets for a long time.
