Finally we have a Touhou gathering going (I'd been lurking the forums for a month waiting). So thanks for getting this started!
My original plan was to bring out my Yukari costume again, but suddenly I have a new plan. I'm coming as Toyosatomimi this year, and I'm almost scared to see a lot of ten desires characters.
As for times, I really don't know. I thought the Sunday 2pm slot worked fine last year, especially with a lot of the bigger meets on saturday (I'm sure a lot of people, me incuded, might be in those meets as well). I put touhou in priority always except I have one big costume for pokemon so if those two conflict, I'm gonna cry lol. Otherwise, saturday it is.
