I posted a link (back on June 26) from the dick blick art supply site that had loads of great art lessons available. I used the family tree lesson during some art classes I gave over the summer. I thought I would share my daughters. The kids enjoyed the lessons and it was great for introducing facial proportions. I did make some changes. I purchased the cheaper green Styrofoam cones and they fell apart super easy, instead of using clay to cover the cone I used plaster and had the kids paint it to look like tree bark. They all turned out great and the kids were busy talking about themselves and their family the whole time.
I also made little Bentley a small blanket to hold. They ran some test on Monday and the news is promising. I will update when I know the details.
