Just before class I had collected a bunch of leaves and I showed how to use them as a stamp and a way to trace them into our paintings. We then talked about what we saw in our textures and how we could develop them into a finished painting.
As they worked on there paintings I sat down and started to develop my painting, pausing to show them what I was doing every once in a while.
This is the demo painting I finished in class.
This is a photo of the class and the paintings they accomplished.
