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.
Enjoy your evenings outside by lounging around a Belgian Fire Ring. An ideal addition to your outdoor setting, this fire pit is easily constructed with Belgian Block and heavy-duty adhesive. Love this style of firepit.
