This picture is from 7/15/07, just before my last session. The background on my arm is finally done! As far as pain goes, we saved the best part for last - I'd say the inside of your bicep is fairly sensitve but further into your armpit is worse. Also, this took a long time to heal and it's still not 100%, especially the area where your arm attaches to your chest since it folds and stretches everytime you move your arm in any direction.
A few people have made comments about how the background takes up most of the space on my arm and there's little room for color. One person went as far as to call it a "negative space tattoo". I suppose you really need to see the tattoo as a single piece covering my entire body to get the right sense of scale, thereby putting my arm into the proper context - it's really just a small part of a larger whole.
In other weirdness: this is old news but in case you missed it the first time around, check out this article about a woman who got an advertisement for a casino tattooed on her forehead. She planned to use the money to send her son to a private school where he "promises to get good grades".
