Hi
I machine my binding to the back of the quilt then fold it over to the front and machine sew it down from that side. I follow the usual instructions for attaching a binding but do it in reverse, I think since I machine quilt anyway, another row of machine stitching visible from the front won't make much difference. If you are careful to fold your binding evenly your stitching will look ok from both sides.
I hope that makes sense to you, good luck.
