 First of all, I'm sorry for the bad picture of the circuit board.

The first image is how I did my circuit board.
The power supply is 9 volts.
The blue spots are my resistors, 100 Ohms each*
The red spots are LEDs. The color of my LEDs are blue so the voltage drop was 3.0 - 3.5 Volts per LED. When making your own LED array use the chart underneath to calculate the voltage drop**.

Red              1.8 - 2.1V
Orange        2.2V
Yellow         2.4V
Green          2.6V
Blue             3.0 - 3.5V
White           3.0 - 3.5V

*Use the amount of Ohm's appropriate to your circuit
**Approximate voltage
