My vote...no border, bind with the same fabric as the outside of the quilt. Do nothing to take away from your beautiful center star. You did a great job on it!!!! You mentioned it would be hanging above a bed that would have a quilt using the border fabric, thus tying the two together. But one day the wall hanging and quilt may part ways and then the border would not have that coordinating quilt to give it a reason to be there. I think the flowery border takes away from the striking beauty of the center of the quilt.
