I would find a fabric that combined both colors, preferably in a batik (I really like batiks). I think that they go w/bargellos. Here are some pics of one of the bargellos that I did. I didn't find the border fabric until the bargello was completed. I used a narrow dark purple as my first border and as my binding to frame the batik border. Just a thought. Whatever you choose will be gorgeous.
