Tattoo Johnny tiki tattoo designs
Tattoo Johnny is an online store that sells downloadable tattoo stencils and color guides that you can take to a local shop to have applied. They even have a "10 minute test drive" option that uses special paper to make a temporary tattoo you can do at home so you can play with the location and size of the image on your body before you commit to the permanent ink.
The site has a nice selection of tiki tattoos, as well as some traditional-looking Maori armband styles.
