Using these sheets is easy. First, place the fitted sheet on your double bed. Use the tags on the sides to make sure it's correctly positioned. Then, put the pillowcases on your pillows. For a great night's sleep, just get in and relax! When it comes to washing, you can use your regular washing machine. Use a gentle cycle with cold or warm water and a mild detergent. 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 the quality and durability of the sheets. If you notice any stains, try to treat them as soon as possible. With proper care, these sheets will last you a long time and keep providing you with a comfortable sleep experience.
