So i'm going to be getting my third tattoo in a couple of months. The thing is, the artist i'm getting it from is in New York while I live in DC. It's going to be a fairly large tattoo, and the artist was saying that it would take ~10 hrs to do. He suggested that I just come for one entire day and do it all at once so I won't have to come multiple times. he claims to have a "light touch" and that I should be ok. To clarify, the "single" tattoo is actually two tattoos on two sides (going "through" me, if you will). The artist is fairly well known, so I more or less believe him, but is this going to be a grueling, tortuous experience?
