This week I’ll be sharing some of things I love to draw. Illustrating fiction in black and white is the greatest happiness. Because dress it up all you like and the deliciousness of colour notwithstanding, it’s the line that underpins it all, the heart and the bones of everything.

Today: children. Lots of illustrators put animals in the place of children in their stories and that’s fine, I do it too. But the importance of young readers – in all their rich diversity and with their small but immense personalities – seeing themselves in books cannot be underestimated.
