Where do you get pre drawn carbon tattoo paper?

A little confused by your answer as it is...do you mean where can you get thermal paper, or the piece of thermal paper that was used for your tattoo? If you ask to keep the stencil, the artist will probably oblige you, but during the application the design on the paper looks quite muddy and bleedy, so there's not much point in saving it unless you're a hardcore scrapbooker. You can get thermal paper online or through tattoo suppliers for very cheap.
