Considerable consideration needs to go into art that is to be permanently pointilled into one's dermis.
Then I saw the water tattoos by the artist Amanda Wachob. According to her website, the tattoos, known as "bloodlines", are done with distilled water instead of ink, thus rendering them impermanent. How cool is that?
It would be a great idea for stars in the entertainment business to have their wedding rings inscribed on their fingers in this fashion. By the time the markings fade, the marriage is over anyway. No harm, no foul, no costly, painful, laser surgery removal.
As much as I admire the one done on the palm, I don't think I have a high enough pain threshold to get a tatt on that particular area.
