Here's our booth setup for the Winters Indoors Farmers Market in Rutland Vermont. We allocated 7' x 7' foot space and also have the advantage with this market we don't have full break down the booth. We just need to remove the valuable items just incase someone decides to be bad.
So we built a U shape booth to maximize the amount of counter space. This will also use to be better able to mingle with customers, sometimes it gets a little crowded but at point we move somewhat into the Aisle.
