Given that stiffness, unless the quilt is very small, you will have a difficult time maneuvering the quilt into the box. Logically it would work great, but in normal life, not so much. BUT!!!!!! try and see how it works. My visual may be different from your actual.

If I have it wrong, never mind!!

LOL
You are right. You need to get it into the right dimensions before sucking out the air. My husband and sis used a space bag to take their clothes with them on a carryon since Allegiant air has started charging for carryons, but not for a personal bag. So, they put several things in a small space bag, shrink out the air and stick it into a large purse or a laptop case. Works like magic!
But you do have to start with the dimensions that you want to finish with. You are right in that you can't really fold it after you've taken the air out. It is waay too stiff.
