To Get the Duvet Into Its Cover, Fold and Shake

Fold both the duvet and the duvet cover into halves and then quarters. Insert the folded duvet into the top quarter of the folded cover so that the duvet’s end and the opening of the duvet cover are aligned. Pick up both at the opening, hold tightly, and shake until the duvet falls to fill the entire cover.
