Okay all... so more than a few people have asked for this Instructable. I hope I am able to explain enough. Sadly I didn't completely document the whole process, but here it goes!
Step 1: Electroluminecent Tech
EL for short, comes in many different forms. Sheets, strips, tape, ribbon, even flexible fabric (although I didn't discover this version until after my suit was made.) The version I used was a cuttable form I first saw on a webseries on Revision3 internet TV. I found it on the site: http://electroluminescence-inc.com/
Attached are some photos. The checked pattern around the perimeter alternates the connection points (anode + / cathode -) which allows the sheet to be cut so long as two opposite contacts are connected to the sheet.
