I've sold at craft shows in NYC & L.A. & shop at them all around the country. I attend some of the biggest & most prestigious like the bi-annual juried one at Lincoln Center here in NYC that cost $600+ for one weekend to exhibit and bring in true artists from all over America - not just local; to some tiny local ones that cost $35 to display (non-juried.)
Even when I shop, I always talk to the vendors to see how they are doing. It really depends a lot on the merchandise, the advertising by the promoters, as well as the economy at the time, sometimes the weather, and the reputation of the fair - how many years they have been doing it and what kind of clientele they usually get as vendors & customers. And whether it is really a CRAFT fair, or family entertainment to take the family for the afternoon & get a sausage hero & a funnel cake.
If it's a newer craft fair with no built in reputation, or close to flea market level, where there is no jurying so your high end items sit next to garage sale level "crafts" at the next booth, or the "fair" provides more entertainment value - no one's going to make much money if your craft is high end. People have actually insulted many vendors I know by offering a cheap flea market price for something worth 5 times the value. People just aren't there to spend at those, no matter how much they ooh & ah. You're part of the afternoon's entertainment. Or they just want a cheap deal. They have no real appreciation of something being handcrafted.
I sold the Christmas right after 9/11 when people felt so guilty for celebrating Xmas. The people who did buy, really made an effort to buy something handmade. In fact, they went out of their way to get my card to include with the gift. They wanted their loved ones to know "LIFE made this item, and as you are special in my life, I am giving you a gift made by a person - not made by a machine." We all learned how precious life was that year. Many other craft artists I know had a good year too. Better than we all expected. People actually sought out their work for the same reason.
The following year when the economy was dismal
all year, most people I know did badly.
In L.A, with the exact same merchandise, I sold in different neighborhoods each weekend, I did well or badly, depending on the neighborhood.
I've known many vendors who've sold for years at Lincoln Center & other highly reputed, juried shows, again it's different from year to year. Most people I know come back each year, because even if they did all right that one weekend in June or Sept, find that the advertising they get by people signing their mailing lists or taking their business cards, more than makes up with buyers deliberately seek them out at Xmas time.
I agree with most of what Mary Jo said. except, any display works for me as long as it's professional, polished, items accessible to be touched (except high-end jewelry, of course,) & organized & some thought went into it. It also depends on the level of the fair.
I acknowledge people with a friendly "Hi!"

when they walk in, let them know I'm available for any help, & tell them to feel free to touch anything. It's
meant to be touched. Then I get "busy" doing something else. I hate being monitored, so I don't want to do it to customers. I gauge each one to see how much talking or listening they want to do. Sometimes "Hi" is enough, sometimes that might even scare some away. So I don't say anything & get real "busy".
I've also found I do better sales when I have a line waiting to buy. I used to rush through wrapping the item & dealing with the money to get to the next person, but I've found when people see one person buying, they want to jump on the band wagon & not miss out. Someone else gave us their
At really slow fairs, it helps to become friends with your craft neighbor. Sometimes we'd stand inside each other's booth and browse as though we were customers. It always drew other people in.
I use
Propay.com as my credit card merchant. They have a $35 annual fee, with a per transaction charge, but
no monthly fees. Great if you only do a few shows a year. I leave one or two well-placed MasterCard signs and that's it. Also, the credit card machine is out in plain sight.
I print up signs on my computer in a nice calligraphy. I don't want to appear like a fly-by-night operation where I've handwritten the signs the night before. I charge too much for my work for a lack of professionalism.
Again, the perception is on what you are selling. If you sell hand stitched dolls clothing, a handmade sign might seem more appropriate & charming.
You didn't mention what you sell. But one of the best books I've read was:
How to Start a Home-Based Gift Basket Business. Even if you don't sell gift baskets -
I don't - well actually I do include some now,

her chapters on finding out what your
target market is, is worth the whole book.

I can't say enough about understanding that concept. It changed the whole way I market, display, what type of shows I will only sell at, what customers I want to target & what price to set to get
those customers. I've even honed in on what specific pieces to make now.
Hope this helps. I, too am interested in reading what other's experiences are.
