HACKSHOME/CAR How to Put on a Duvet Cover By EDITOR APPROVED - 04/06/2018 0 449 With this simple trick, changing a duvet cover is unbelievably easy. Turn duvet cover inside out. Lay duvet cover on bed with the opening at the foot of the bed. Lay comforter on top of duvet cover. Starting at the head of the bed, roll both the duvet cover and comforter together toward the foot of the bed. Once at the end, invert the duvet cover opening around the ends of both sides of the bundle (like a sandwich baggie). Button or zip the duvet cover closed. Unroll the bundle in the opposite direction (back toward the head of the bed) and fluff.
