I found out that I had 3 packs of un-opened Shrinky Dinks on my shelf. I bought them about 2 years ago but haven't played with them at all. So I tried tonight. It's not an exact science, but it's definitely fun. They are so tiny after shrinking! Should I make them into little rings? They look so dainty. :)
PS: The real things actually look better then the photo. The lineworks becomes really thin and dark after shrinking.
