Using these sheets is simple. Just put the fitted sheet on your long single bed, making sure to align it with the tags for a perfect fit. Then lay the flat sheet over the bed and tuck it in neatly. You can add the pillowcases to your pillows for a complete look. When it comes to washing, use a gentle cycle with mild detergent. Wash them in cold or warm water, not hot, to keep the fabric in good condition. Avoid using bleach as it can damage the cotton. After washing, tumble dry on a low setting or hang them to dry. This will help maintain their softness and durability over time.
