For the circuit, you will need:
- an LED (mine is about 4mm diameter)
- some conductive thread (I got mine from http://www.aniomagic.com/)
- watch batteries (mine are 377 or LR626) - the LED runs on 2, but you'll want spares
For the bear body you will need:
- a little bit of polyester fiberfill (available at anyplace that sells sewing or craft supplies)
- thread (I use clear nylon, but you can also use a color that matches your fabric)
- a scrap of stretchy fabric (like thin t-shirt material) for the battery compartment
- a small piece of upholstery velvet or similar material for the body of the bear (keep reading for details)
Fabrics for making miniature bears can be purchased from specialty suppliers such as http://www.christiebears.co.uk/
If you don't want to order fabric, you may be able to find upholstery velvet or thin ultrasuede at your local fabric store.
The fabric that I am using is a miniature bear velvet with a white grid backing. However, any fabric that is thin and won't fray at the edges should work. The bear will hold its shape better if the fabric isn't stretchy.
- a ballpoint or very fine felt tip that will write on the back of the fabric you are using
- something thin and blunt like the handle of a crochet hook
- small scissors
- a tiny needle
- a needle that works with your conductive thread (I had to use a bigger needle for my conductive thread)
- hemostats (also called locking forceps). Either straight or curved will work, but they need to be small.
You can get hemostats from the same places that sell miniature bear fabrics. They are used in surgery, so will be sold by medical supply companies, and I've also seen them for sale with tools & pliers used for electronics. I think I've also seen them sold as fish hook removal tools.
