This pretty little quilt stands on it's own and needs no addition of any kind. The idea of just simple quilting will let the quilt be the show.
I did make a heart in a frame once and I added some seed beads right on the seam line between the heart and background, in the ditchh, so to speak. This little bit of sparkle might be cool on this piece but not detract from it.
Like the quilt very much. Great colors.
