The Winnipeg Anime con (Aikon) is notorious for selling out of artist alley tables in minutes, and I've only managed to get in last year by fluke- BUT if you win 1st or 2nd in the mascot contest, you are awarded a table.
plus- the theme this year was Sci Fi... I couldn't resist.
I'm going through Comic Con withdrawal right now... I've been filling out all my Artist alley forms these last couple weeks, getting my tables confirmed for the year, and am JUST itching to attend a show.
Also bought a banner stand :) cannot wait to get the banner printed! (pics will be posted as soon as I have it constructed)
