Quentin Blake is one of my favourite children’s book illustrators. In this video courtesy of The Guardian online he says he doesn’t know the relationship between his characters when he starts drawing them. Rather, his knowledge of them grows as he spends time creating them.
My experience as a writer is similar. I generally have a rough idea what part a character will play in a story universe. But, as I spend more time with them, they still have the capacity to surprise me. I like NOT knowing everything they could do as a plot develops. Planning everything out in advance could stamp out the goshness of a story as I build it, just as I prefer to read a book in full before I watch its adaptation for television or cinema.
Anyway, I’m glad a man of Mr Blake’s experience is still revelling in the newness of creativity. That’s inspirational.
