If it is going to be an heirloom quilt for the family, and not used often, I would pull the Poly Poofy stuff out. I was given a couple of my DMIL's to refresh "repair"and all were done with poly batting that just disintegrated. All that was left was a pile of sandy uuck, so I had to remove all the beautiful hand stitching she had done, change the batting and start over. I did them FMG in as close to the old pattern as I could. I don't like trying to save those old quilts, but they were in such dire need, and both of my SIl's were heartbroken by the polyester breaking down.
