If you have never had Shrinky Dinks as a kid you should try them out today!
You can get them at any craft store. I would get the frosted ones. I like them the best because you can use colored pencils and sharpies and I think they just look better.
You can cut or push out shapes.
Then start drawing!
Don't forget that you can hole punches so you can make them into charms or whatever you want.
Then Shrink those Dinks!
