Using these Casey cotton sheets is easy. First, spread the flat sheet over your mattress, then place the fitted sheet on the mattress and use the tags to ensure it's in the right position. Tuck in the edges neatly. For a decorative touch, add the pillowcases to your pillows. When it comes to washing, use a gentle cycle with mild detergent in warm water. Avoid using bleach as it can damage the fabric. After washing, tumble dry on a low setting. Don't over - dry them to keep the softness. Iron on a medium - low heat if needed. These sheets are made to last, so with proper care, you'll enjoy them for a long time.
