If I wanted to trace the codes on as a stencil tattoo, would this work if it was copied by free hand?

I want you to get the best results possible.I am not sure you could adequately capture the structure of the wave pattern in free hand form, and that is where your personalized solution lies – in the information stored in the structure of wave pattern itself. You could, however, create a tattoo for yourself that focused on the golden line drawings (symbols) then that could serve as a touchstone activation for you to reconnect with the information carried in resonance pattern of your Personal Codes.
