Materials: 28" x 28" MDF board
1 1/2" Drill bit *USE a Forstner Bit. The bit I used didn't work well
I painted the board with black spray primer, and then white automotive spray paint. Then I used a paint brush to add some stars.
I cut a hole in a piece of cardboard to make a template for the orbits surrounding the planets. Then I lightly sprayed white around each planet. Then using a light spray of black in the centre of each orbit, it created a nice shaded look. Then I applied 4 coats of Varathane, with light sanding in between.
Finally, I touched up some orbits with some paint to create some cleaner lines. Here's the game all laid out!
