Once upon a time, the kids & I made Shrinky Dinks. Remember those??
They were in a Toy Story mood, but there was also a purple My Little Pony (Ginny) and a pretty cool key (Junah). Unfortunately, I didn't take any photos of their projects, but we sure had a blast!
Ali supplied the sheets we used:
Afterwards, I ordered more for future, including some with patterned sheets, which might work well for the kids in a free-form way.
It's been decades since I made a Shrinky Dink, and there was a bit of a learning curve. That's what came out of the oven, and I learned two things: 1) an insulated pan might not have been the best choice, and 2) whether insulated or not, preheating the pan is probably a good idea.
I have to admit that I sort of loved them all curly like that, but I stuck them back in the oven...
I was able to flatten out the bigger piece (1-7/8″ x 2-1/4″), but the smaller one wouldn't come apart!
It was really fun!!
