I
decided to go as my Gaiaonline avatar for Anime North 2004.
I'm open to trying to make pretty much anything to go with
your costume... as long as it's not weapons, armor or a wig. Most
things that can be made with fabric are do-able for me.
Pricing depends on the complexity of the item and the materials needed
to make it.
