heh... it's as doable as a prison tattoo
it requires the expensive machinery that each disc manufacturer has. my tutorial would only be about designing
or if you want the prison tattoo style, get some silver leaf or gold leaf, heat up some shaped metal, and have at it. theoretically, you could take a design to a laser engraver, get an etched-metal copy of it, put it on the stove, and then press it against a disc covered in silver leaf.
