Using your Casey cotton fitted sheet is a breeze. Just place it on your half - queen bed (50cm) and tuck the corners under the mattress. The tags on each side will help you get the orientation right. For a good night's sleep, make sure the sheet lies flat on the bed. When it comes to washing, you can use a regular cycle in your washing machine. Use a gentle detergent to keep the fabric soft. Avoid using bleach as it may damage the cotton. After washing, tumble dry on a low - heat setting to maintain the sheet's shape and durability. Iron on a medium - low setting if needed. With proper care, your Casey cotton fitted sheet will serve you well for a long time.
