Fun with shadow puppets! You can do these with kids of all ages. I did them with two and three year olds. While the cognitive ability to figure out the idea of the shadow, etc, was very different, everyone still had fun doing them.
DIY: Modern Colorful Mobiles via Project Wedding. I love the idea of using different shades of white vellum to make these paper mobiles for a wedding reception. I am off to the paper store to see what is available.
