I've just about finished my first attempt at an EL wire project.
It's very simple - a t-shirt ($20 from Farmers) with a spiral of green EL wire. The spiral is a good shape to start with, as it doesn't involve any cutting and is low-stress on the wire. I didn't even have to terminate it - just used a standard length and made the belt loop thing with the surplus. I used hot melt glue to stick the wire to the shirt, passing it through the fabric every so often to try and give it some structural integrity. I was going to sew the wire in place, but actually duct tape on the inside of the shirt seems to have done the trick. Also, I've used tape to hide the bits of the wire I don't want to show.
Why? I'm going to this psy-trance doof in Aussie - flight's this arvo!
