It is a competition. But it is judged by me on all manner of things that I shall not divulge. Therefore the winner will need style, skill and a damn good sense of humour. Those things are worth a cookie.
P.S. I won't just accept any old tat. I've basically got to say "wow" when I see it for you to win. And I mean it about the cookies! I'll even let the winner choose the flavour (from a short list of milk chocolate or white chocolate, as that's all the local shop is likely to have).
