He and his wife, Lisa, began designing and hand-printing their own range of cards in their London studio way back in 2000. Drawing on their backgrounds in art and fashion, they've since stocked the world's finest galleries, museums, boutiques and department stores with design-led goodies. These days they illustrate and adorn greetings and homewares from an old post mill on the edge of the South Downs. One Shoe Two Shoes is Edward's second picture book, following the 2017 publication of Big Box Little Box with Bloomsbury.
