Recycled Plastic Shrinky Dink Necklace

I was inspired by the "Sheer & Clear Friday Challenge" on the new DIY site Kollabora. I used a #6 recycled plastic container as my "Shrinky Dink" material, a few jump rings and some chain to make this octopus necklace. Here's how I decided on this particular project:
1) My friend's octopus theme wedding invitation was surprisingly cool.  2) I've been researching Chihuly style art lessons on Pinterest. 1) I have an honorary degree in Shrinky Dinks. It was bestowed upon me by the kids I teach.
