Did you get a look at Bonnie Hunter's slide show of the some 70 quilts that were in the show and tell in Nebraska. The best one was an En Provence that had a 1 1/2 to 2 inch wide framing border, perhaps 4 inches from the body of the quilt. It was like framing it and presenting it. Looked finished and wonderful.
I would have a 7 inch outside border, then a 2 inch framing border and a 4 inch distance border next to the body of the quilt. I realize that the borders are going to make the quilt much larger, but that is what I would do. Maybe you don't have that much fabric left or don't need it that large. Up to you.
