I don't know if he's going to Blizzcon or not.. but I made a ConBadge of his Gnome! He said he liked the color purple so that's why he has purple. I think this turned out great. I wanted to make him feel better.
If you want one to go with you to Blizzcon (or any convention really) let me know I'll give ya' a price. (Doubt it, but hey doesn't hurt to try. lol.) The one you'd get from me would be mailed to you and be laminated with a badge clip.
