I made a dojo pattern pin. I chose this because the dot can fit LED in it and it also looked good. I had three designs, I chose this because my teacher chose it for me. I learned how to sew the battery holder on the felt. My felt pieces are too thick, which is hard to make the LED through it, but I cut the felt afterward, so the LED could get through. Tips: Never give up! If you made a knot, don’t tighten your thread! Next time, I want to have 2  LEDs on my product.
