I would put a border that "holds" the quilt, much like a frame on a picture. The quilt (which is lovely) is very active, lots of colors, patterns. For me, I prefer dark colors as a small (1 or 1-1/2 inches) inner border then a wider outer border which can be busy, such as piano keys. I would bind with the same color as the inner border for continuity and for again holding in the busy border. Just my two cents worth...
