i finally did it! i made myself a terrarium after thinking i would well over a year ago. i'm not sure if it totally counts since the moss isn't completely surrounded by the glass, but it's good enough for me. i used some ceramic mushrooms i bought a couple of years ago and the little fawn was a gift from australia.
it makes me happy. i can see this becoming an obsession.
and hopefully i won't kill it. (like i did the strawberry plants. and the bugleweed. and possibly my lavender.....)
