I, also, am sorry you didn't sell anything.
A couple of comments based on my experience.
1. After doing dismally at three "Craft Shows/Fairs", I started looking around for shows/ markets that require that items for sale MUST be SUBSTANTIALLY made by the artist (and you are an ARTIST - don't let anyone tell you otherwise. I place ALL of the people who show work here and other sites as ARTISTS and you should, too, including yourself. Some of us are still learning our ART and some have progressed very far, but we're all artists!) That means NO "made in china" and some paint added.
I have no bone to pick with crafters. I consider some of them Artists, too, because of the quality of their work and their obvious talent. The problem is that at most "Craft" shows, the majority of the customer base expect to be able to pick up something for under $10.00. When you show items priced above $20.00, they think you are out of your mind. They have no idea what it takes to make a quality piece.
2. Each day of a show is totally different from the others and all shows are different, too. Therefore, having a variety of items to sell is a necessity. I use a Price point range starting at $20.00 and going up to, for the time being, $200.00. As I get better, the high end will go up. I live in a market that that does not have much in the way of disposible income. I have been told that if I take my work to Chicago, I could 3 to 4 times what I charge here, but, to me, this is an AVOCATION, NOT a JOB! I'm not trying to make a total living at this. I make enough to upgrade my equipment, buy exotic woods, and pay partly for vacations, each year.
Finally, spend some time walking local shows: say a 50 mile radius, to start.
Look at the type of work there, is it about the same or slightly better quality as yours?
Look at the customers. Are they singles, married couples, retired? Each of them have things they will and will not buy. Are there a lot of Families. How old and how many children. Obviously 3 -4 small children usually means that this is an outing to look, but not buy.
Very IMPORTANT! Are the customers walking around with their hands in their pockets, or with bags in their hands.
I'm sure there are other thoughts from others here.
Best of luck at future shows. Artists DO NOT COMPETE with each, we support and assist each other. At least that is what I have found.
