CALLY BOOKER lives and weaves in Dundee on the east coast of Scotland. She first learned to weave while working as a data analyst in the public sector and, after studying Handwoven Textile Design at Bradford School of Art, she set up her own studio. Her background in mathematical modelling continues to inform her creative practice, and she is always energised by the prospect of a new data source that she can explore through weave. Formerly a tutor with the Open University, Cally brings her passion for lifelong learning to her acclaimed online weaving courses. Her work has been exhibited widely in the UK and overseas. She is a member of the Society of Designer Craftsmen and a past president of Complex Weavers. The ideas and techniques in this book are the product of her experience as a practitioner and teacher of multi-layered weaves.
