Yuffie: I'll definitely have Sieg done in time for JACON, however if you want me to bring him to Metrocon as well, let me know.
It'll give me time to revise the costume (if needbe).
As for the Final Fantasy Ball, I'm looking forward to seeing the various FF costumes depicted there. Last year, we had a surprise "Tonberry" guest enter the ball near the end... a young kid, with a dead on costume complete with lantern and butcher's knife.
I think the site has pictures of him too...
