What You Will Need:
EL Wire: To illuminate the edges of the standard matrix you will need 10' of 2.2mm wire
DC-AC Inverter: the EL wire I ordered came with an 3V (2AA battery) inverter but you can build
your own using the wonderfully written instructable How to Add EL Wire to a Coat or Other Garment
Screws: see the third step for more info.
Step 1: Thread the EL Wire
Step 2: Attaching the Inverter.
If you are building your own inverter, then you can attach it using nuts and bolts, duct tape or any other method, including this one. I'm sure you can figure it out, you're smart people.
