i would say laser removel, as that would take away most of the ink work. failing that maybe you could get a nice design of a flower or something like that to get it covered up.

Nice tattoo. Im looking to get one myself on my leg at the up and coming north lakes tattoo show in april this year. I have been playing with the idea of skulls before but seeing yours now kind of seals the deal for me. Was it painful getting it done on that part of the leg?
