You will need:
- Conductive fabric. I used Cobaltex from Less EMF http://www.lessemf.com/fabric.html
- Wonder Under or some other iron-on adhesive sheeting (you can get it at fabric stores)
- Laser cutter
- Clothing iron
- Soldering iron
- Stuff you want to solder
- rhinestone glue (like Gemtac) for gluing your components to the fabric.
