Valentine's Day Shrinky Dinks

Do you remember Shrinky Dinks? I loved loved loved these as a child, but I wasn't sure if my 2.5 year old would be ready for them yet. We happened to find ourselves at a Hanukah party in December where a bunch of craft tables were set up, and my child gravitated to the Shrinky Dink table.
How we did it:
Materials List
