Using your Casey Cotton Fitted Sheet and Pillowcase Combo is easy. First, put the fitted sheet on your queen - size 50cm bed. Use the tags on the sheet to make sure it's in the right position. Then, slip your pillows into the pillowcases. For washing, you can use a regular cycle in your washing machine with mild detergent. Avoid using bleach as it can damage the cotton. After washing, tumble dry on a low setting. To keep your sheets looking and feeling great, iron them on a medium - low heat if needed. With proper care, these sheets will last you a long time and keep providing you with a comfortable sleep experience.
