This is my favorite craft fair. Period. The organizers take such good care of you in every way. It can be tough to get in (the odds are about 1 in 3) but the organizers make a commitment to bringing in a significant number of new vendors every year (at the last fair in May it was 50% new vendors). You can find the application here. Last day to apply is September 21st. Notifications are sent on September 30th.
