Computer-aided design (CAD) is being used more and more in the fashion design industry. Although most designers initially sketch designs by hand, a growing number take these hand sketches and put them on the computer. CAD allows designers to look at designs of clothing on virtual models, and in many colours and shapes, therefore saving time by needing fewer adjustments later. The fashion designer’s next step is to take the rough sketch or model and develop a more specific working pattern. Usually, the designer will make a rough model of the design by creating a toile. This is made by sewing inexpensive material (like muslin) to make a rough model of the design. When this is placed on a mannequin-like dress stand, the designer can see how the material will drape or hang on a human form.
