Step 3: Wiring the LEDS
I used stranded wire to connect each of the lines of LEDs to each other. I left enough slack in each of the wires to not cause tension on them, and soldered them to the LED leads.
Once each of the paths was soldered together, I sewed together the remaining side seam and one shoulder seam, leaving the other open. Then I completed the circuits by wiring the LEDs across the seam and finally to a AA battery pack near the hem. (remember, long legs = +, short legs = -)
After soldering, I clipped the ends of the leads and covered them with dots of hot glue, both to secure the connections and protect the girls from any sharp edges.
