I really like your quilt: the colors, the design, the visual impact -- all are stunning. In my opinion, a work of art deserves a frame. Even a small white frame will give a viewer's eye a place to stop and make it focus on the center. I've learned, however, that a personal choice is always the best one. If you like a border, put one (or two) or two on. If you don't care for borders, leave them off. Either way, it's a beautiful quilt.
