I have a theory that hobbies are the most powerful force in the economy. Whether boating or breed dogs or fandom or a craft, people will spend resources they can't justify anywhere else, collecting tools and equipment and supplies, traveling to conventions and shows, building special rooms in their houses, needing particular vehicles, etc.

Beadwork has the advantage, at least, of being very small. But yeah, there's stuff involved. Lots of little stuff. Whee!
