You can also get a glass display case at Hobby Lobby or similar place, and fold a quilt so that a pattern shows, then place them/it in the case for display in your favorite room. That way they are protected from further damage, not damaged by improper restoration (and some of them are so used it may be impossible to restore), AND visible to see and ooh and ahh over.
And along the same lines, one of the owners of my LQS just reproduced a quilt his (yep, it's a man) gr-grandmother had made. It was beautiful! You could do that too. That way you "tie yourselves together" with the quilt she made and the one you made.
