A springtime terrarium centerpiece

A couple weeks ago, a friend asked me if I was interested in going to a class at a local greenhouse on how to make a terrarium. I didn't know a lot about terrariums, but I was intrigued, so I said yes!

The class included all the supplies we needed -- a glass container, rocks, charcoal, soil, moss and plants -- plus a handy-dandy handout on how to care for them. I seriously, totally kept all the little tags on my plants so I could tell you all what I planted in here...and I lost them.

So, I wish I could tell you what I've got growing in here, but I can't, except that I remember the low-growing green one is called baby tears. I remember that because it kind of bummed me out, but the plant was pretty so I used it.

The instructor said to keep the terrarium in medium light. It makes a lovely spring centerpiece on the dining room table.

Every few days I give it a mist with a mister. I'm really nervous about keeping it alive, since I'm got a pretty black thumb. So far, so good.

I'd love to find a tiny, adorable little animal figurine to put in here. I'm on the hunt for just the right addition.

Have you ever made a terrarium? Any tips for keeping it alive -- I think I'll need them!
