I've never really been interested in conventions myself. I've had a bad experience with a creepy kid at my high school, and apparently guys like him are a dime a dozen at conventions. Not to mention, I did read the "Convention Horror Stories" thread in this very forum. I am warming up to the idea because of artist alley, though.... the prospect of buying things sans shipping fees is pretty appealing!
Do you think you could maybe do a private photoshoot with a few good friends and then share them online? That way, you wouldn't need to go to a convention to share your costume.
