In case you missed it, the Artist and Crafter's Alley is now accepting applications for the 2012 convention. I've received several, so I would jump in as quickly as possible.
You can find further information, including rules and guidelines for this year's Alley, in the Artist's Corner of the forums here: http://sogencon.org/forum/index.php/topic,14691.0.html
Please be sure to read the rules before submitting. We hope to hear from you soon!
