September 1 --
Mable House and South Cobb Arts Alliance
This is a direct link to the application, which is kinda buried in their site. The deadline was Monday but I have it on good authority that they will continue to accept applications for judging until they reach capacity or they hit the jury deadline (9-15)
September 4 -- VSA Art of Georgia Holiday Art Sale This is a very long sale and I am not familiar with it but I think it looks like a good organization.
VSA arts of Georgia seeks artists with and without disabilities to participate in our 2009 Holiday Art Sale. The sale is an opportunity to sell your work in a prime retail location in Downtown Atlanta at the height of the shopping year. The sale is one of two annual fundraising events for the organization; our mission is to provide access to the arts for Georgians with disabilities and with low income.
