I love these little moss topiaries because you get a bit of nature inside your house without having to worry about things like watering. You can buy the moss balls at most craft stores, but it can be a little less expensive to make them yourself. For these particular moss topiaries, I bought and spray painted little terra cotta pots with a gloss white spray paint. To make the moss ball, I just wrapped the dried moss around the styrofoam ball and used straight pins to attach it. They are the perfect size for a windowsill or table decoration.
