Preschool crafts using a half pint milk carton?

I have 21 half pint milk cartons and I need some ideas on what we can make with them. The kids are 2-4. Thank You!

ive done a few things with milk catons actually, we made easter baskets,fire trucks for career day, valentine boxes, log cabbins,pencil holders, bird feeders.
any questions on these just ask! good luck!
