First of all, I love your quilt. You had such a good idea to use the four patch posey blocks within the quilt. As far as the borders, I would either use the green as another inner border and then use just the main fabric, or I would use your method number 2. In my humble opinion, I think that if you use method 1, it pulls your eye away from the center of the quilt and you lose your focus a little bit.
