DIY stone fairy house or "gnome home" made with individual stones from a sheet of stone mosaic used for backsplashes. The roof is an old copper vase. The finial is a brass nut topped with a small granite pebble.
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.
