Portal Through The Woods by ~Asphodel-Foxx. [read a lot of fantasy books when I was kid, wishing I could find a portal to another land, and if I ever stumbled upon this in the woods I would have lost my mind]
Richard Shilling on Land Art for Kids what a great idea for outside leaf/nature sculptures. make sure to watch an andy goldsworthy documentary too! Should you appreciate arts and crafts you really will really like this site!
