I did this show last year. Nice place, excellent promoter, booth sitters helping people, the mos amazing art I have seen in an art show, had great weather....but very low attendance. The few people who actually came to shop showed up at around 7 p.m. Before then, really no sales. I truly don't know what else can the promoter do to attract more people. There was also another show downtown Columbus the same weekend and another one in Grove City (about 20 mins. from downtown) that is pretty popular.
Promoter did a great job, great communication, you saw him at the show, he kicked out a buy/sell....I mean, excellent....but sales were pretty low. A painter close to my booth sold NOTHING in all 3 days....
