Chew, I'm assuming that it still looks the same as it did on page 19 of this thread.
A couple of ideas come to mind. If you are comfortable with applique..you could do a round with the flowers and hearts from the center or you could just balance a few motifs on opposite corners...
Or, you could repeat the "steps" on a previous round but bring out the darker green and blue and yellow. You would need to keep in mind that it shouldn't be so strong that the last round couldn't be added easily though..so maybe not overwhelming on the darker colors...
Or...you could bring some longer lines to it and do some stripes with maybe an appliqued heart or flower blocks along to break it up a little...
I'll keep thinking. I know it will finally "talk" to you and probably ask you what took you so long to figure out what language it was speaking! :D:
