You might be better to make sure you name it so people realize it's a craft fair/show. The Emporium of Wonder and Awe Craft show might be good. Otherwise people are not going to know what it is and not stop.
Try advertising on craigslist. That's where I find most of my shows or word of mouth. Most shows I do are school/church events and they either mail you a application and you mail back. Keep the names of people and send to them year after years.
