Small Tips that make Big Help
There are a plethora of small tips that I've come across and encountered during a lot of my trips across the different tips. Some, I found, actually make a very big difference that could shift the whole paradigm out of focus. Others are hardly noticeable, requires a lot of effort but don't make the cut and are more trouble than what they are worth. But the other tips, they area godsend to keeping your customer attention, reinforcing them and fortifying your reputation.
First tip, sending a personal, pen-written note with your thanks and hope for continued business in the future. Writing the thank you note makes the whole thing more customer-involving, and makes it very appealing for the customer at hand. This involvement makes the customer more enthusiastic with his business with you, so you can expect a call back or another deal in the future. Make the note as personal as possible and don't make it mechanical or scripted. Let the customer think "Now here's someone who thinks of me. I can't wait to see if he has something else!"
Another great tip while inside the art fair: make sure to never leave your post unsupervised. That means to not ever, leave your post. You. Not some other person. It should be you. You can let other persons man your table, but only for security or other reasons. If anything else, you have to be there when meeting the customers. If a prospective client sees your table and asks around, he would be wanting to talk with the proprietor and not just some guard. So make sure to only leave your post when it is absolutely necessary, if it is lunch time, or if you have to do something important
Be a friend, be an agent, be a customer; but don't look like a proprietor in front of the client. Everyone has a pretty bad impression regarding salespersons (you could see the image of a widely-grinning, hat-wearing salesman with an evil glint in the eye, and an avid stare at your wallet). Customers would feel more comfortable if you would go down to at least their level (or away from the manager-high-seat) and act like another perusing customer.
The over all idea is: bring your business to a personal level with your clients. Craft business isn't about just making money with your personal handiwork, but it also means meeting the people who are buying your products. Creating an interpersonal relationship with your clients is one way to reinforce your market base, and to also create a network of your own which could benefit you in the future.
