Where can an artist go to find information about arts and crafts shows?
Call your local Chamber of Commerce and find out if they have information of any art guilds in your area. There may be other types of art organizations that may not be classified as a guild who can provide such information. Libraries, colleges and universities usually are updated with current information of these shows as well.
ZAPP is an online registration of one's self for the art community in the US. From there one can apply with an application fee to pay to any show registered through ZAPP within the United States. This however does not guarantee you a spot in these shows as most shows jury your work and decide if they want you in their show.
One of the best resources is your local newspaper if you have one.
