Using these sheet sets is a breeze. Just put the flat sheet on top of your mattress, tuck it in neatly, and then place the fitted sheet over the mattress. The tags on the fitted sheet will help you orient it correctly. For the pillowcases, simply slip your pillows inside. When it comes to washing, use a gentle cycle with mild detergent in lukewarm water. Avoid using bleach as it can damage the fabric. After washing, tumble dry on low heat. These sheets are durable, but it's still a good idea to not over - dry them. Regularly changing and washing your sheets will keep them fresh and ensure a comfortable sleep environment.
