Using forks for printing. Would make such a cute project for Kdg. I could see them making some very funny porcupines! Fork stamp would be good for hay stacks or a dog. Can use fork for upper grades and manipulate so just 2 prongs were printed and etc.
My idea - Each child decorate a hand and attach it to the big tree. (Make paper hand cutouts from your children's hands. Write things they are thankful for on the hands and you will build your own thankful tree!
