Your items must be unique enough to sell and also be creatively priced. I always think since I quilt/sew that " I can make that!" How many craft fairs have you been to where everything looks alike. One Arts and Crafts Fair I went to in Idaho had nothing but all the same pottery items, rod iron yard art and hanging chairs that were REALLY expensive. Probably about 50 booths.... I am not trying to discourage you, buy all means go and experience...check it off your bucket list... Just talk to lots of folks who work the Fairs for a living and get their PRO'S and CON'S. Best of luck !
