What are the best fonts to use for tattoos? Thanks.

Depends on what you like. Letter shape? Curly or not? Script like or not? Neo Nazi or not? Burnt deep into the bone or not? The best doesn't exist. What you like best is what is best for you ... or maybe not ...

ClarehTM, at the top of the page, you should see a link called "Themes". Most of the fonts that would be good for tattoos would be in the Calligraphy section.
