sevens

OK, new to TFP so Im not sure if this goes here but... I'm thinking about getting a tatto, and its probably going to go on my wrist. now I know that people say dont put it somewhere that visible but I figure I can throw a watch on and be alright. My question is do tattoo's on the wrists work, with the veins running right under the wrist, and if thats not a problem, how long does it take to heal up because it takes abit of time until you can show it off right? just throw some thoughts my way and anything else helpfull about the subject, thanks.
