I am doing a belt and I want to get the letters darker than my dye I am using. I have only stamped a couple of times all my stuff is plain (no tooling) minimal stamping. The customer wants the letters to be darker. The example they gave me is attached. I have practice using a dark brown dye but it just looks a little browner. I have also used a highlighter but only minimal results. Any suggestions or tips. This is really my first time doing this kind of stamping.
