When she was little she was obsessed with animals. So much so that she wanted to be one. Her mom knew this and sewed her an assortment of costumes she could wear all year round. She was also obsessed with drawing and from a very small age knew in her heart she would be an artist someday. If....she worked hard enough and practised. Currently Sarah is an internationally published illustrator with several adult colouring books, children's board books, activity books, and greeting cards under her belt. She lives with her family in Kansas City. Her work and other notions can be found at Sarahwalshmakesthings.com.
