I would just wash it gently in the bath tub then hang or lay flat to dry (I drape quilts over laundry baskets then turn a fan on) and then put it on display on a quilt rack or a shelf. Attach a label for future generations. I have several antique quilts (not from family) that are beyond repair. They're my favorites.
