Freya and I attend many play dates. We usually have a craft of some sort to do. Here we are painting an egg crate and transforming it into a caterpillar.
We spent the play date reading The Very Hungry Caterpillar
while eating many of the items the caterpillar ate!
To make an eggshell caterpillar:
Cut off the top of the egg crate. You can use this for your paint pallet. Then cut the egg crate into half lengthwise.
Have your child paint the caterpillar.
Once dry, hot-glue some googely eyes on the front. Then poke two holes in the top of the "head" and put a pipe cleaner onto each hole so each end sicks out of the top. You can then shape the pipe cleaners to make them look like antennae.
