Choose the stars and constellations you want to feature on your board. This project has The Big Dipper, Draco, The Little Dipper and Cassiopeia.

It is important to first sketch out the entire sky (circuit) - where all the stars (Blue LEDs) go, where each of the constellation (Blue LEDs with Green edges) goes. Once you have figured that out, draw this circuit on a piece of cardboard.

All the Blue LEDs will be connected in parallel on the main circuit.
