Fairy Houses / cover with moss, pebbles, etc.
Fun Fall Craftivity: take a photo of children pretending to 'blow' into the wind. Then add leaves for a realistic effect.
Elf house on a tree. Definitely something for little kids or for grandparents that like to have children believe in fairies and elves.
Bing : Reggio Emilia Schools-- love the leaves on the windows! http://www.pinterest.com/search/pins/?q=reggio%20emilia&rs=ac&len=9

Andy Goldsworthy inspired. Children trace each others outline on the pavement with chalk and cover themselves up with nature. Even better would be to trace the image in dirt with a stick.
