Elf house on a tree! That would be cute in the garden, especially in the tree over grown with ivy. How about some battery tea lights in the windows during outdoor parties. I hear the fairies/elves whispering "home school project" in my ear.
Headboard to Bench! Get an old headboard for a kids twin bed at Goodwill. Paint however you like! Then add wood panels and a cushion! I definitely can do this with the headboard I don't use anymore, it can be my own lil project!
