Built a little terrarium

I had an old fruit jar that I was using to hold a lavender scented oil, but I decided that I wanted to grow some moss in it instead. I put a layer of charcoal on the bottom, then some dirt, then what looks like club moss and that very dense, short, slow-growing type of moss. I painted the top of the fruit jar with some nail polish and set it with my other plants. The terrariumĀ seems to be happy so far!
