For my birthday, Nerissa made me a Terrarium Kit with all the parts needed to make a terrarium: rocks, charcoal, soil, decorations and a glass vessel. It’s an awesome gift because I’ve been wanting to make one of these for a while now. You can find lots of instructions on Google and many how-to videos on YouTube. The only tip that I’d add is that an oversized pair of chopsticks works really well for placing objects neatly where hands can’t reach. I put the arrangement below together in half an hour, racing against time as the sun set. For a first attempt, I like it. It’s pretty rewarding to design your own miniature eco-system. I can see why it turns into an obsession for some people.
