I love the backs of the cards almost as much as I do the front! I can't even begin to count the number of stickers I lost in elementary school due to the teacher taking them away! It was OK though as my mom taught in elementary as well so any GPK stickers she would confiscate that weren't claimed by parents at the end of the school year became all mine!
I hope to share more of my favorite stickers from the box when I get more time. That is if anyone wants to see them.
