Like all of us do, normally when I need a logo on a figure, I either print one on the computer, or try to steadily paint one on. My usual results include a printed logo that has lost too much detail, or a painted sloppy mess. For the last NJC (BPRD) I wanted to make small belt-buckle BPRD logos for my figures, and thought I'd try something new -- at least new for me & customizing joes -- millefiori.

Here was my setup, including: aluminum foil, pasta maker, polymer clay, x-acto knife, paper logos, cardboard cutting surface, and of course, not shown: damp paper towel
The polymer clay I used was Fimo, from Michaels. I went with basic black, but for the red, I found this clay with glitter in it. Since the buckles on the film versions of the figures were metallic, I thought this clay would add something special. Now, I'm not so sure that it did, but the stuff sure bled red all over my hands...
This picture shows the amount of clay I used from each block:
