Well, I've done a lot of pottery/craft shows by now and I have a couple of suggestions that have helped me out in the past.
1) Bring some high energy snacks, you'll need them! A canister of mixed nuts from the bulk bins at the grocery, bananas, and bagels are excellent. Some sandwiches and bottles of seltzer or just plain water are also musts.
2) Be friendly but not overeager. What the folks said above is definitely true. For every twenty people that come in to your booth probably only one would even consider parting with cash. Don't scare them away. If someone instigates a conversation with a question then you're free and clear. If someone is spending a lot of time looking I usually like to use the ice breaker "How are you today?" accompanied by a friendly warm and sincere smile. It's an energy thing that you're doing and it's very subtle. Each potential customer will have their own personality and approach so you have to feel it out.
DON"T sit there in the corner like a spider in its web and read the newspaper. You can sit and take a breather from time to time but pretend to be busy. Arrange and rearrange your stuff. Polish blades. Fiddle around. Joke with your partner if you have one with you. Keep the energy up. (That's why you need the fuel)
3) Present your pieces in an attractive manner. This is SO IMPORTANT! If you are going to have a table, buy a queen size black cotton sheet from JC Penney. You can order right online although their site is slow. Everything looks great against black especially metallic objects.
Also very important: Make some simple little stands out of 1x6 pine boards and either use light stain and poly or paint them. They are cheap and easy to make and will allow you to vary the height of your displayed items. It is really helpful to have your display broken up a bit and definitely gets people more interested.
4) Make up some cards that tell a little about you and your stuff. People want to know where you're from, what you specialize in and what your philosophy is. You can make a sheet of four or six on the computer and then take them to the copy shop and have them xeroxed onto attractive recycled card stock. Then cut them up by hand. It's incredibly cheap and looks very classy. BTW, business cards are also a must and can be done the same way or ordered.
Hope these tidbits help you out!
