Using these Casey Cotton Sateen fitted sheets is a piece of cake. First, identify the tags on each side to make sure you place the sheet correctly on your half - queen bed. Then, simply tuck the sheet under the mattress. For washing, you can use your regular laundry detergent in a normal cycle. To keep them in top shape, avoid using bleach as it may damage the cotton fabric. Hang them to dry if possible, or use a low - heat setting in the dryer. This way, your sheets will stay soft and durable for a long time.
