Being able to sketch is an essential part of fashion design and sewing; a good sketch shows the designer/sewist how a garment's proportion, style lines, and colours will work on the body. Most designers sketch their designs on top of "croquis," or pre- rinted body outlines. However, until now, the standard croquis for women have shown elongated, stick-thin, unnaturally proportioned, and off-balance bodies. In Gertie's New Fashion Sketchbook, loved house author and fashion-sewing celebrity Gretchen Hirsch teams up with illustrator Sun Young Park to reinvent the traditional croquis for the 21st century, with hundreds of croquis depicting realistically sized and proportioned body shapes in balanced, life-like poses. Also included are an overview of the design and sketching process and a visual history of garment component styles to empower designers/sewists to create sketches for ashion that will be flattering for women of all shapes and sizes.
