And then another thought said, "How about just sticking it in the second fairy-tale mashup you're working on?" Someone could tell it as part of the history; I like having a lot of background fairy tales; and it might not even work as a stand-alone central tale. For one thing, the heroine would have to have a very odd point of view, being made out of snow.
Ah, decisions, decisions -- as soon as I thought of that, I realized where I would put it in the second mash-up. Where I haven't even started the list of included fairy tales. (I ought to start that list. Not quite as crucial as the character one, but still useful.)
