Just NOT losing weight sounds like a beg step for him, I'm glad to hear it.
I'm still gonna get this one I posted a while back:
I think between my shoulder blades (not much more than 3-4 inches across, so a bit bigger than the pic, but not too much). That'll be inconspicuous enough there.
It'll be exactly as it is in the pic (my other tattoos are color, so it'll be my one "black only" tattoo). I figure I'll do a pic of the artwork and pic of the tattoo when I get it done (probably not gonna be til october).
