Using these Casey Cotton Sheet Sets is a piece of cake. Just put the flat sheet over your mattress, then place the fitted sheet with the tags facing the right way to ensure a proper fit. The pillowcases go on your pillows easily. When it comes to maintenance, you can machine - wash these sheets in cold or warm water. Use a gentle detergent to keep the fabric soft. Avoid using bleach as it might damage the cotton. Tumble dry on a low setting to prevent shrinkage. If you want them to look extra smooth, you can iron them while they're still a bit damp. With proper care, these sheets will serve you well for a long time.
