The eyebrows can be fairly common, especially with asian friends I've known (well actually, the mothers of asian friends). Kinda weird to think they'd pluck the eyebrows so often that they never grew back, and THEN got a tattoo to replace them.
Oh well, who said make-up has to make sense.
I've had a friend who got the eyeliner tattooed on...she said it hurt like he!!, and then came off maybe a week later. Fun times.
