We’ve been meaning to make a terrarium for a while now, but when I found this glass dome in the attic, it seemed like a good time to try.  I couldn’t quite find the right container, but we used a pot that we had around the house.  I just filled it with these water-absorbing rocks from a pet store, then a layer of dirt, then the plants and some rocks and moss.  These instructions were helpful.  There’s also a little three-legged ceramic dog in there too.  He was an attic find as well.  I made sure that I used all tropicals since the closed dome will trap the humidity.  I’d love to make an open terrarium with succulents next.
