Sarah Horne grew up in snowy Derbyshire, UK with some goats and a brother. She learnt to draw whilst trying to explain her reasoning for an elaborate haircut at the age of nine.

Alongside working on some very funny children’s titles, Sarah has also worked on commissions for The Guardian, The Sunday Times, Kew Gardens, Sesame Street and for IKEA as their Children’s Illustrator In Residence.

She now draws, paints, writes and giggles from underneath a pile of paper at her studio in London.
