Pattern for a garment is the blue print on the basis of which the fabric is cut and the same is achieved by two methods: Flat Pattern Method and Draping Method.
Flat Pattern Method: This a method where in body or dress form measurements are taken for developing a pattern.
Draping Method: In this method a piece of two-dimensional fabric is draped directly on a dress form or figure and made to fit on the dress form to achieve the desired look or shape. The official definition for the word pattern is "a repeated decorative design."
