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.
Painted fireplace screen hung on wall as a headboard. Totally doing this! I have a sleepnumber bed and it's been hard to find a headboard I like. I HATE just standing a headboard behind the bed and not attaching it. This is perfect!
