Grandmother’s Treasured Quilt Nearly Destroyed Part I

I am finally working on a Double Wedding Ring quilt made in the thirties that a treasured grandmother made and a granddaughter and her friends nearly destroyed.

It started with a bon firer with a group of cold teenagers. One of the teens went in the house and retrieved a quilt and a few blankets. The quilt became entangled on the wheel of the four wheeler and was dragged under one of the rear wheels. As you can see by the pictures the damage is pretty extensive. How will I repair it??? In the coming months as I repair this quilt I will take you on this journey.
