Laurel's book, Tailoring a Woman's Jacket, is available at: laurelhoffmann.com/product/tailoring-a-womans-jacket/ It provides the information you need to draft the supporting patterns, then sew the copied jacket or coat. These are the procedures used in industry to produce jackets and coats for preferred customers. Laurel tested the book with design room and other professionals in her continuing professional education college classes to make sure all can be easily understood.
In this video Laurel shows how to trace off the patterns from a purchased, ready-made garment without removing any stitches. When she finishes tracing off the patterns she will then use the instructions she wrote in her book, Tailoring a Woman's Jacket.
