Using your Casey Cotton Fitted Sheet & Pillowcase Combo is easy. First, find the tags on the fitted sheet to make sure it's placed correctly on your queen - sized 60cm bed. Then, put the pillowcases on your pillows. For best results, wash the sheets in cold or warm water with a mild detergent. Avoid using bleach as it can damage the fabric. After washing, tumble dry on a low - heat setting. This will help maintain the softness and durability of the cotton. Also, iron on a low - heat setting if needed. With proper care, these sheets will keep you comfortable for a long time.
