My hubby says they look rustic.
A few days later Kathy was looking at the Ravelry ballbands and found one where both colors were variegated and realized what a nice combination it was that she wouldn't have thought of.
Somehow we decided that we should close our eyes, dive into our dishcloth stash (of which we both have way too much of), and choose random colors. My first grab was orange and self striping pink. I didn't think they'd look good together but they do. I can see a lot of choosing colors for ballbands this way in my future.
