Ack, too many things to quote! Do you have a picture of the cosplay by any chance ZM?
I don't think I've ever seen your work before! <33 And the fact that she agreed to $200 for the next one makes me think she knows a little more than she's letting on. *Shifty eyes* I'm really glad you got her to give you a much more honest price for the next one though. Although, I don't know, maybe I'm super snobby or something when it comes to cosplay but I think hand-made stuff like you're doing should cost around the $300 range at the least. You're not a Chinese sweatshop on Ebay churning out pre-patterned 10+ of these things.
As much as I like a deal I love seeing crafters getting paid fairly as well! Ah, as long as you're happy though, all is well!
