Because there isn't enough Halloween in my sketchbook at the moment. But to be totally honest, I don't think I ever ran around All Hallow's Eve with just a cardigan. Show of hands, who else designed their costumes to fit over a winter coat? I distinctly remember Halloween '88 being the only pirate in history to wear a turquoise parka.
And jumping forward a few months, I have a quick survey. I've had a few people ask if I've ever thought of offering a calendar and I've been mulling the idea over. Is that the sort of thing other people would be interested in?
