1. Turn the back of the quilt cover over and lay it flat on the bed, then lay the quilt flat on the quilt cover with the four corners aligned.

2. Roll it up from the side without zipper to the head.

3. Turn the rolled quilt out of the zipper mouth and turn it out at both ends, thus turning it from the back of the quilt cover to the front.

4. Slowly open the rolled quilt and smooth it. The quilt cover was flat and went in. Then clean the four corners properly and shake the quilt.

5. Zip the quilt cover and fold it again. You're finished, isn't it simple? You don't have to change the quilt cover in the future.
