This quintessential guide to patternmaking offers comprehensive coverage, clear illustrations and easy-to-follow instructions, providing users with all the relevant information necessary to create design patterns with accuracy regardless of their complexity. Covers the three steps in the development of design patterns—dart manipulation, added fullness, and contouring—with a central theme that all designs are based on one, or more of these three major patternmaking and design principles. Includes a fashion sketch for each project with an analysis of the design, and focuses on pattern plot and manipulation for developing the patterns. Illustrates several methods for knock-offs, and dedicates new sections on fitting corrections for the basic pattern set and the four pant foundation; menswear; patternmaking for bias-cut garments; revised drafting instructions and standard measurement charts; how to modify the bodice to fit the different sizes of bust cups; constructed support for strapless designs, and more. Presents additional and more challenging design projects for the advanced reader. For dressmakers, home sewers, manufacturing companies, and professionals in fashion design and fashion merchandising.
