If you can stand one more suggestion, here's mine. I'd not only cut off the dark blue, but I'd cut back the gold border back to the fleur-de-lis corners and the first decorative border - it looks like a beautiful old-fashioned ornate gold frame to me. THEN I'd cut out some wide(r) border strips, maybe 5" wide to accommodate the fleur-de-lis corners, from the center fabric that's on the bottom row of your complementary fabrics photo (dark blue with some stars); lay those underneath the trimmed-to-the-"frame" panel and use a very narrow satin stitch/extratight zigzag in gold metallic thread to affix the panel to this dark blue border; then trim the excess blue border fabric to 1/4 inch from the gold thread stitching. The very few stars that would show on this narrow border would keep my eye's interest, while drawing it outward from the center panel. Then you could easily audition each of the other fabrics for the final border(s) simply by laying the revised panel on top of it.
