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.
Wonderful mix of material for garden path. Cobblestone sectioned between random pattern of bricks (reclaimed bricks offer a softer mellow tone of age along with irregular edges) and plantings of different types of thyme. Bordered with bricks.
