Sales are about flow. People arrive, see all the booths in the field and head over there. They do the circuit then go home, not realizing that there are actually people inside. I would not have any parking around the building, and make that area a booth area as well. Do not block the door or even the whole front of the building, There was a tent kind of blocking it. Move the tent away from the door and have a circle of small booths encouraging flow to the door. Have those booths curve around and direct traffic to and from the building. You need a HUGE sign directing people inside. Do not let that sign be blocked.
Inside vendors also have to realize that people are there to buy birds and that is where their money goes first. Their products have to be really well priced to make people want to spend their bird money on soap, jewelery or art.
In advertising, have two separate ads. One to appeal to those that are looking for crafts and baking, and an other for bird buyers.
In the field, make sure there is an obvious path from the birds to the building. Not only was Marsha's set up in a low wet area (poor Marsha) but her trailer blocked the path that people wanted to use. It was a struggle to find a way around Marsha to the parking lot. I would set people up on the south, west and north of the field, completely leaving the east side open. People will see both the booths near the building and in the field.
Your booth prices are reasonable and should not dissuade people from getting a booth.
People in the field MUST bring a tarp or a tent to protect from sun and rain.
It was a great sale Triple J. It is only your second one, and I would consider both a success. Give yourself a big pat on the back.
