A fun activity that all of my kids enjoyed when they were young is, foot painting. For paper, we visit our local newspaper printing press and ask them for the ends of their newspaper rolls. They are always happy for us to take them off their hands. They are free to us and I use them for many projects with the kids - this being one of them. Just pour some paint into a bowl or bucket and have fun creating! Kids love the feeling of the paint between their toes and using their feet to create works of art.
