A crochet border will dress it up just enough I think. Last week I made one entirely in crochet with one of my little flowers to add a bright spot. Unfortunately my muscles didn't enjoy the constant repetition of the one stitch--there's a twisting motion in the wrist involved in crochet which gets wearing after a while. I've had to be careful since then not to do more than a bit at a time until things settle down. That's a pity because often it's the meditative rhythm of the work that I enjoy.
