I recently worked with stylist Atip Wananuruk doing temporary tattoos for a sunglasses editorial in Remix Magazine. Each look was themed around a style of tattoo: Japanese, 80's
"fineline", 70's biker, Native American, Russian prison style, floral and 50's traditional American.
I only had an hour to spend on each one (as opposed to 3 or 4 hours for a real tattoo) as each model was timed to come in every hour from 9am til 3, and from there would go straight to the shoot. I learned a lot and by the time I did the last one (the 50's sailor girl above) I had my technique locked down. I think my over all favorites are the sailor girl and the Navajo chest piece.
