You need to contact them and ask this question of someone who really knows the answer. If you don’t have contact info for them, you can find it through Google.

I don’t know about an association, but you can check with your local chamber of commerce to find craft shows in your area. Once you get into a few and get to know the promoters / organizers, and show you are responsible and follow the rules, you will be on their list for future shows.
I do know there are books you can buy that will list the more well-known art and craft shows, but they tend to be a bit costly. There are different books for the different areas of Florida, but you can also get regional books. Due to cost, I’ve never purchased any of these books.

Your local chamber of commerce would have information on the craft shows in your area. You can then contact the organizer of the show and speak with them about being a vendor.

Some cities have an events website that would have that information.
