Add additional borders to top and bottom. Pick other colors you want to highlight and use those and then make the outer border the same all the way around. That's one of the things that is great about scrappys! I would do the 'extra' borders the size of the small squares (2"?) and personally would do a red, blue and maybe a green. But it totally depends on who is getting it and their color preferences. I really like your top - and don't beat yourself up about the goof, everyone of us has done something similar!!
