I have a sister who is a craft fair seller, and this year, aprons are great. She charges $15 to $25 for hers, but they are really cute, and she makes seasonal aprons (Valentines, Christmas, birthday, Mom, Dad, I'm the cook, etc.) If this is your first at something like this, go "lots of little, cutie things, not real expensive. Try to talk with someone who has done one in the past--(and make sure she won't be competing with you, hahah). And I haven't ever heard of a vendor's license for craft fair things; but we're in TN and I don't get out much. Will you be having to share your profits, or do you pay a fee for each day you set up? Have fun. I am glad I don't have to do this type of thing for a living (my sister does); too much work for too little money for my taste.....
