Using your Dover 3 Piece Organic Cotton Duvet Cover Set is a breeze. First, open the button closure at the foot end of the duvet cover. Insert your padded insert (not included) into the cover. Make sure to tie the internal corner ties to the insert's corners so it stays in place. You can then place the duvet on your bed and arrange the matching shams for a complete look. When it comes to maintenance, simply toss the set in the washing machine for a quick and easy clean. As for storage, fold it neatly and keep it in a dry place. Avoid using harsh chemicals or bleach as they may damage the fabric and the antimicrobial treatment. Also, don't over - stuff the washing machine to ensure a thorough clean and prevent the fabric from getting wrinkled.
