Each finger has an LED on its fingertip and the LEDs are connected to the conductive material. After troubleshooting, the final layout of the circuitry is shown below.
The LEDs' negative terminals are each connected to a line that is printed along each finger, and all five lines are then connected together to a single ground. The positive terminal of the LEDs are connected on one line (the red line) which takes a shape of the hand's outline.
A simple drawing of the final layout of the conductive material.
