I just made this terrarium for a friend and am super excited about it. Of course, the desert theme never escapes me.
I was thinking about walking through the desert and of all the random objects that I have found. Everything is in plain sight where it is exposed to the harsh sun and wind, and washed clean by an occasional late summer monsoon. It's not hidden under inches of forest duff and decaying in the flash of an instant like it does here in the Pacific Northwest. The story is right on the surface, so to speak.
In the desert, you are almost certain to find elements of metal, glass, jagged rocks, and bits of old bones from times past. I used glass eggs, an old metal lock,a piece of petrified wood, and a skunk skull.
