Katara's necklace is a blue choker with a light blue, hand-crafted jewel bearing the waterbending symbol. But since I made this cosplay on a major budget, its just a plastic shrinky-dink.
Step 1: Step 1: What You'll Need
- A circle template (mine was about 2 1/2")
- Shrink plastic or #6 plastic
- Scissors or an xacto knife
- Blue marker
Step 2: Cutting the Plactic
Cut out the circle and fix the edges to be as round as possible
Step 3: Colour Your Plastic
You'll want to colour your plastic with some sort of blue marker (I used a Faber-Castell PITT artist pen) which is a waterproof Indian ink.
Step 4: Shrink the Plastic
Heat your oven or toaster oven to 350°, and place a rack in the lowest position. There's not really a specific amount of time you need to leave it in for, but I left mine in for a minute and a half. You can just watch it until it stops shrinking, and don't worry about the plastic curling up because it'll smooth on it's own.
Step 5: Poke a Hole!
Poke a hole as soon as it comes out of the oven or heat it up again if it cools
Step 6: That's All Folks
Now all you need to do it put a jump ring in and attach it to a blue ribbon. We did it kids!
