This book explains, in simple steps and non-mathematical terminology, how to create repeat patterns in a line, on the plane, as tiles and as Escher-like repeats. The book also shows how to make ''wallpaper repeats'', where the elements of the pattern merge into each other, apparently seamlessly. <p><p>Using letters as the basic elements, the book demonstrates how all repeat pattern-making comes out of four simple operations: translation, rotation, reflection and glide reflection. It will provide the definitive one-stop pattern-making resource for professional designers and students across disciplines, from textiles and fashion to graphic design and architecture.
