Good luck! Will you be posting progress photos? I'd love to see how you do the daggers, jewelry, and armor, since it seems everyone approaches it a bit differently.
Have you read any of the "Those Who Speak" comics that are currently being released? Izzy actually wears pants! I'm considering doing her "Those Who Speak" costume for next year's Dragon*Con, but it's in the running with a couple of other Dragon Age costumes and I haven't decided for certain which one I'll be making yet. :P
