As an avid enamel pin collector, I decided to make my own to see what the process was like. I did a few sketches and decided on a notebook paper airplane. I learned how to prep the file and other details like, how a line of metal should be added between each color. I chose a black metal, soft enamel pin, 1.25 inch size with 2 military clutch attachments. Available for purchase for $6 + shipping.
