No matter where you are think about settting up a display with books, props, informational flyers, and how-to's. It might be the lounge at work, the library, classroom, church foyer, hospital lobby, clubhouse, etc. The best promotion comes at the "grass-roots" level.
Encourage literacy by promoting books and reading, foster learning skills by honing listening and imagination skills. Create a sense of community by telling local tales.
Scope out the possibilities, get any permissions, and then set up a small space. Add to the event by pulling up a stool and telling stories as an added feature.
Encourage people to read, to tell, and to listen and everyone is a winner!
