Thanks, Connor! I have been making these since I was a kid. There was a book at the local library detailing how to set them up, but the plant suggestions were a bit large for these smaller setups. It's definitely a learning process seeing which plants do well in the different setups though. Googling jar terrarium will bring up quite a few sites outlining the basic construction. I like to try and apply basic aquarium layout guidelines when planning out the hardscape. So far, plants that really lend themselves to the closed setups include riccardia, anubias, hc, and other liverworts and mosses.
