No return needed.
Just doing things spontaneously, interacting with the environment, trying to be helpful...
Offering free services, opportunities, vouching for nice stuff around, that sort of thing.
Organising workshops outside.
Stands at fairs or the like.
Encouraging creativity and reuse.
Who came because they liked it; who made stuff happen in turn; who made the place just as much as I did.
Trying to make things accessible, and to provide a platform.
Working with local artists and groups, independant crafters.
