To spray paint clothespins (or similar things), clip them onto an old cardboard box and tape the flaps up. they'll dry there and you won't have to worry about waiting for one side to dry at a time. Might use clothes pins for my traffic light next year!
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.
