My DH and I do several craft shows each year. You want to have a variety but not so much so that the people are overwhelmed. Unfortunately what will sell at one show may not sell at another. Don't forget to take yourself something to sit on and water in a cooler. If you plan to do future shows make sure that you keep track of what did sell and those things that people did like or improvements and changes that people might like. If there is time before the show you might want to walk around to see what other prices are so that you will know if you are inline with others. We are just starting our research for any new items that we will add this year. My DH does woodworking and I do sewing and quilting. I find that my baby quilts and grandma's paddles sell the best. Try to have everything visible and easy to get to. Change is a must. We use cloths for our tables in plain colors.
