I also would be in favor of cutting it up. I would cut it down the middle (or maybe off center) of each white stripe and add a strip of something else from end to end, then do it again horizontally, just picking a spot in the middle of your rectangular blocks. Would still be a grid, but I'm envisioning almost a plaid. Of course, it is fine just the way it is so you could just finish it up and send it along it's way.
