Using these Casey Cotton Bed Sheets is a breeze. Just put the flat sheet over your mattress and tuck it in neatly. Place the fitted sheet with the tags facing the right way on the mattress. The duvet cover can be filled with your duvet easily. For washing, use a gentle cycle with mild detergent in lukewarm water. Avoid using bleach as it can damage the fabric. After washing, tumble dry on low heat or hang them to dry. This will help keep the sheets soft and extend their lifespan. Also, make sure to iron them on a medium - low setting if needed. With proper care, these sheets will serve you well for a long time.
