I love your quilt. I think it has enough pattern that it doesn't need more in a border. It can stand on its' own and I'd add a small border of a darker color and then another one of lighter material and bind it. I think a busy border takes away from the beauty of the quilt but I really like the third one, I don't think I've see that used before. Isn't nice everyone has so many different opinions. But the person to please is you.
