As another activity in our backyard exploration, O and I collected leaves to make Summer leaf creatures. We laid them out on the floor and put hardback books on them to flatten them. After a couple of hours, we removed the books and made leaf creatures. I made a girl wearing a dress, so O made a leaf boy so they could get married. I love the face that she drew on her leaf boy :)
In the interest of full disclosure, I should admit that I enjoyed this activity much more than O did!
