In chosing a site and design, try to envision it in twenty years time when the skin begins to lose it's youthful appearance. Lots of gals chose small tatoos and have them done where a piece of clothng will hide them if necessary. When I had to inject a blood thinner there is a certain radius around the navel where one doesn't really feel a needle. Go beyond it and man it stung. It's about 2" and you want to stay in that zone.
