Zoe Waring is a children’s book illustrator and designer based in Newcastle upon Tyne, England. Zoe loves the warmth and humor so often found in children’s picture books and is a little obsessed with cute baby animals, which often make an appearance within her artwork.

She works in a variety of materials and loves creating engaging characters to make people smile. When she’s not drawing in her sunny studio, she can be found exploring the beautiful British countryside.
