From the drawing board to the dress rack, Fabric and Apparel Patternmakers help put clothing designs into mass production. These skilled workers outline precise patterns of each part of a garment design. Then they use the patterns to create templates that are placed on layers of fabric to be cut into parts for production. Patternmakers also calculate dimensions for reduced and enlarged versions of patterns to make various sizes of the garment. This work is done in areas that are generally quiet, well-lit and air-conditioned. Patternmakers usually work 35-to-40 hours a week. They need steady hands and good vision for cutting accurate patterns. They also need several skills, including knowledge of fabrics, proficiency in mathematics for calculating sizes, an understanding of technical drawings, and the ability to outline patterns on a computer. Certificate programs that teach patternmaking are available. Some workers learn through on-the-job training. Those with some vocational education in apparel production have the best chance of employment. Although many textile industry jobs have been reduced by technology and foreign competition, Fabric and Apparel Patternmakers are still needed to replace those who retire or move on to other jobs
