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.
I have a partial set of Princess House punch cups (and the big bowl) that my Grandmother gave me; they would make a cute gift, if I used nicer beads, maybe some birthstones, and made one for each of us grandkids.
