I wouldn't take it apart. If you were going to do anything, I'd add another border around the outside--maybe a 6" yellow and finish it off. Someone will use it.
Taking it all apart and redoing the sashing, etc? Not this lady.
It is a lot of work that you could be doing something you want to do--not just a rescue. Besides the uniqueness of it is what makes it so special. If you make it "really nice", then it won't be a story.
Besides, when it is really cold outside, it might just get "stacked" on a bed trying to keep someone warm and it is not important how beautiful it is then.
