How to use:
1. Turn the quilt cover over and you can see two ropes at the four corners.
2. When the quilt is laid flat, you can see that there is a round circle on each corner.
3. Take one of the two ropes from one corner of the quilt cover, put it in the ring of the quilt cover, and then tie the two ropes (the other three corners are handled in the same way).
4. Put the quilt completely into the quilt cover and lay it flat, so that the quilt will not wander around in the quilt cover.
