Your best bet is to sign up ($$$) for
www.craftmasternews.com or
http://festivalnet.com. They list all the craft show and festivals. You can search by distance from zip code. They are wonderful but some things to note. Most of the bigger shows require you to fill out applications months in advance. You'll also need good pictures of your products, photos of you making the product and photos of your display.
Jewelry is a very competitive category as there are many many people competing for the limited spots in the category. Really spend some time creating your display. It could separate you from the others. Don't get discouraged when you don't get accepted, just keep at it. Go to shows and see what others are doing and adapt.
Good luck, it's alot of fun and there is LOTS of money to be made. Just be patient and keep an open mind to new ideas.
