Using these Casey Cotton Bed Sheets is a breeze. Just put the flat sheet over the mattress, then place the fitted sheet on the mattress and use the tags to make sure it's in the right position. The pillowcases can be slipped over your pillows easily. When it comes to washing, you can use a regular laundry cycle with mild detergent. Don't use bleach as it might damage the fabric. After washing, tumble dry on a low setting. To keep the sheets in great shape, iron them on a medium - heat setting if needed. And remember, store them in a dry place to avoid any mold or mildew growth.
