I find a lot of shows with google searches. look for craft shows by your state, county, town. Lots of churches and schools do craft shows - especially near the holidays. Check the websites of nearby towns for their events. Also, community groups like Lions Club, Rotary, etc. often do fundraising craft shows. There are websites like Festival Net that have festivals listed. And once you get to a show, talk to your neighbor vendors - ask about shows that they have been to in the area. The more you network the more you learn. Also, try to think about your target audience - do you want family type events where their are young families with kids, or are you looking for older, retired folks - a lot depends on what you are selling.
