Wow, that border really showcases the French Braid.
Or the French Braid really sets off the border.
It's a fabulous combination.
And your LA quilter will have access to hundreds, if not thousands, of patterns. Depending on the equipment, he/she can custom design/free motion exactly what you're looking for. See what's available there first.
Please post another picture after it's been quilted. I would really like to see what was done.
