I wonder if we could do a design like this but actually use stones and concrete to stick them together. Would be one of the more permanent houses we ever made for May Day. The carved clay is a good idea too though. Much easier. Each kid could build a floor.
Fairy Houses for the Garden NOT Faries.. HOBBITS!! or just some of us ingenious Irish folks! Amazing what you can do with a a hollow tree and some ivy and moss.. and reclaimed hinges and wood.. A real Hobbit entrance!!
