Using these Casey Cotton Fitted Sheets is a breeze. First, simply place the sheet on your half - queen bed (60cm). Use the tags on each side to make sure it's properly aligned. Tuck the sheet tightly under the mattress for a neat look. When it comes to washing, you can use a regular laundry cycle with mild detergent. Avoid using bleach as it may damage the fabric. After washing, tumble dry on a low - heat setting to maintain the sheet's softness and shape. With proper care, these sheets will serve you well for a long time.
