Here's a few pics of some of my miniature gardens.
The castle is hardware cloth with cement soaked toweling draped on.
The Fairy and Gnome homes are made from cement I cast in homemade molds.
The Hobbit house is cement over a styrofoam base. The Hobbit house is the largest, the door is about 5" tall.
I always decorate it for Halloween, this year my grandchildren helped!
That's cool, if you click on the picture it makes a photo show!
