WOW WOW WOW :shock: those are beautiful, you are so lucky to have those. I agree that you should use each one for two seperate quilts.
With regards to the quilting...are you a hand quilter? If so then it would be such a nice chapter in the story of these quilts if you could do them yourself.
If not, then I would say machine quilting them would also be fine, if I were you I think I would prefer it, as it would stengthen them. But then I can't hand quilt so I would have no other option!
I think hiring someone to quilt them is an ok idea, but doing it yourself would really add to their history.
can't wait to see what you decide to do.
