Step 15: Customizing
I wanted to outline the inside of the center hole in black to make it more visible, but if you choose a black top, you would obviously not need this step. I also outlined the outside of the circle in black to match the inside.
I also did outlining stripes with a Sharpie permanent marker on the top and sides to make it easier to focus on the target at far distances.
When you are done decorating and customizing you are ready to play!
