The new border would have batting, like a regular piece of the quilt BUT I would attach it to the underside of the old quilt, with an non-batted layer of fabric (QAYG style). This would become a new inner border on the old section. I would secure it, by adding two rows of quilting to the new joining - one along the base of the scallops and one along the edge of the single layer, an inch or so in from the first line.

I hope that makes sense. It's easy to see it, in my head. . . but not so easy, to explain it.
