Today's project: make a terrarium. Inspired by a store in SF called Paxton Gate, I did a little research and went to the garden store. $60 bought me potting soil, sheet moss, activated charcoal, river rocks, five little plants, and a glass apothecary jar. A little steep, but if/when I make another terrarium, I'll only have to pay for the plants and jar.
Apparently I should only water it every few weeks. If this one survives, this might be the beginning of a new obsession.
