I agree with IrishRose. If you can add a tiny border (or flange or piping) of a different color, that would be ideal. You could try to match it to something in your print, or you could pick a neutral like beige or black, or you could go with a direct complement in an indigo-violet. Just something to break it up a bit. Once you've done that, I'd probably pick the yellow border to make it look more warm & cozy. The white makes it look more cool & crisp.
