You, the designer, will still develop your overall garment design, but having these sometimes more tedious details taken care of for you will make the overall process more enjoyable and build your confidence in a successful outcome. Begin by developing your overall garment plan and work your swatches as described in Knitwear Design Workshop. Sketch out your working schematic, select your desired sweater silhouette, enter your measurements and required ease, and the app will generate stitch-by-stitch charts called stitch maps that you can use to write your pattern.
