DIY Drawing and tracing using shadows: great craft/art for kids too. "Nature and shadow- what if we take out the paints and paint in the lines…."… great idea for tracing. Take a quick pic then don't have to worry about sun changing places.
Fun area for boys and all those Tonka trucks and John Deere tractors. Backyard Idea, for sure!**- definitely NOT just for boys, my 4 year old daughter would absolutely love this & play in it every day we let her.
