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.
For my dad! Fishing pole picture frame - this is not something I would do for myself and my home decor but it is soo cute I think it would look great at the lake house or you could do bright frames and a kiddy pole for the boys room
