Using these Casey Cotton sheet sets is a piece of cake. First, spread the flat sheet over your mattress and tuck it in neatly. Then, put the fitted sheet on, using the tags to make sure it's the right way around. For the pillowcases, just slip your pillows inside. When it comes to washing, use a gentle cycle with cold or warm water and a mild detergent. Avoid using bleach as it can damage the fabric. Tumble dry on a low setting to keep the sheets soft. Iron on a medium setting if needed. With proper care, these sheets will last you a long time and keep you comfortable night after night.
