Using your Hanae 3 - piece duvet cover set is a breeze. First, open the button closures on the duvet cover and put your comforter insert inside. Then, use the hidden tie - backs at the corners to secure the insert so it doesn't shift. The two matching shams can be placed on your pillows for a complete look. When it comes to maintenance, this set is machine - washable. Just follow the normal washing instructions for bedding. Avoid using harsh detergents or bleach to keep the fabric in good condition. Also, make sure to dry it properly to maintain its texture. You can complete the bedroom decor by adding the coordinating Hanae Euro shams and decorative pillows, which are sold separately.
