Gussy Sews Inpiration Challenge: Gardens

This weeks Gussy Sews Inspiration Challenge is gardens. The second I heard this I instantly thought of the pictures I had recently seen in Martha Stewart Living magazine of moss gardens. She brought them in the home and I thought they were beautiful. They seem so magical. I can picture a fairy living in them.

I would love to have one of these in my home. I'm just not sure what the easiest way to get the  materials is. Any ideas?
