For the pocket detail, we wanted to have a piece of EL that split in two, this is possible but a little trickier than just a single piece. Make sure you're comfortable with soldering to EL wire since you'll need to solder to two ends, thus doubling the difficulty
You'll want to cut the first piece a little long, again, and then solder two pieces of ribbon or other thin stranded wire to both the core and corona wires. Each one can go to another EL piece.
