For inspiration, I found that I was mostly drawn to the black or white enamel with gold metal. I like the shiny appearance. I also tend to like the hand drawn nature of some of the pins.
My favorite apple metal pin here catches my eye with color and contrast particularly in stark geometric patterns. I like the contrast of the white and the color.
Some rough sketches of thoughts for things I wanted to consider arranging in my pin.
Working some of the ideas out with the pin tool in illustrator:
I wanted to put all of the themes onto the pin and liked the arrangement and concept but I realized that I wanted the pin to be 1” and the details would be lost or not possible to manufacture.
So I simplified and colored using the idea of the raised gold metal with black and white paint for these 1" pins.
