Ashling Lindsay is an Irish artist from Belfast. She has been making picture books for eight years and has been included on some of the most prestigious award lists in the world. Her approach to making art changes with each book. She responds to every text individually by experimenting with color and composition, using a variety of materials until she finds a combination that fits the text. This nearly always begins with analogue experiments - marks and paint on paper. Ashling teaches illustration at Belfast School of Art.
