"Artists Beware"

Well, I'm not sure if I can give a very good answer to that since I'm not sure exactly how work with foam bases go and what exactly is the situation with the builder, but I'd think that if the builder used the money to buy foam and such supplies, she'd send those along the head and pay the shipping so they can be used by another builder (I'm assuming here since at least I've seen such be done in other fursuit cases so it might apply) or the head and partial refund and shipping since technically this would be the commissioner cancelling (even though the cancelling would be done from a legitimate reason).
