I feel a bit like Dr Moreau as I scour the secondhand shops, looking for potential subjects for transformation. Perhaps I have seen too many Toy Story films to not imagine them trying to hide behind each other on the shelves. Yet still I persist, as you will see. Yesterday I bought a Bagpuss, which is absolutely not for unpicking and restitching. He sits on a high shelf as a presiding spirit. All I need now are some singing mice.
