So I… you know, I had a sort of sequence of the picture books got into more of a sequence, and the latest one is called Angel Pavement, which is a title which I stole or borrowed from JB Priestley, from a book that was published in 1932, I think, the year I was born, but… which is a completely different kind of book, needless to say. But that is about… it's about the pleasures of drawing, really, and it's about two girls who are… you don't know, but they are angels, or at least we know, because we can see it, because it's a picture book we can see their wings, but normal people can't. And they produce a sort of magic pencil, and in fact those drawings done with the magic pencil, which draws in the air, are just done with a pencil that's got four different colours in it… which we had a lot of when I did an exhibition called Magic Pencils, so I got a lot in the studio already. And so it really is about a drawing competition and a pavement artist, who can't put paving stones into the exhibition, so he's enabled, by the use of this pencil, to draw in the sky, because the little girls who are angels can carry him into the air. But it was really… the idea of a drawing competition, plus the idea of the drawings you could do with this pencil. And it's about the pleasures and purposes of drawing, really, in a simple way, and it ends up saying but when you start drawing, you can never be quite sure what is going to happen next. So it's supposed to encourage people to draw, apart from anything else. But that was... really also partly came out of a number of activities that came about with… from being Children's Laureate.
