Using this duvet cover set is easy. First, place your duvet insert inside the duvet cover. You can adjust how warm it is by choosing different inserts. The two pillow shams are great for sprucing up your pillows. When it comes to cleaning, remember to use cold water and a gentle cycle in your washing machine. Don't use chlorine bleach, or it might damage the fabric. After washing, tumble dry on low. If there are any wrinkles, you can iron it on the lowest setting. Also, keep in mind that the inserts are sold separately, so you'll need to buy them if you don't already have one.
