So I found an artist I really liked (Anne at Black & Blue Tattoo in SF) and had it redone this evening. The whole thing was re-inked, and we made the blobs a little bit bigger and brought them down a little bit lower. So far, it looks really good; I hope it heals better this time.
I'd forgotten how much fun it was to have needles poked into your ankle for an extended period of time. Ow!
