One of the favorite crafts my son and I like to do is making things out of toilet paper rolls. I'm not sure what it started with, but now my son won't let us throw any toilet paper rolls away! He helps me come up with ideas of what to make with them.
A while back we made this train with tp rolls, with a little help from some other cardboard.
We had recently watched Dumbo, so he wanted to put animals in the train. We found some little stickers with animals, and a few other stickers made it on there as well.
Most of the fun is in the making of these, but my son usually likes to play with them for a while, too!
