Pattern and colour are at the heart of all my illustrations and I create patterns in my sketchbook and preparatory work that often ends up as part of a final piece of work. It also plays a major role in my handmade books, whether as endpapers or as the subject of the book itself. Many of my patterns are created with hand carved rubber stamps, and I am endlessly fascinated by the potential of a repeat pattern, especially when you introduce colour overlays to really make it sing.
