Principle and application of difference matching in apparel pattern design

A garment is made up of many pieces of fabric sewn up one after another in an orderly way.From the configuration of finished garment,it seams that the two sides of a seam are of the same length and same shape,in fact,not always in that situation.On one hand,stereoscopic feeling and fitness to the wearer are essential requirements to a garment.On the other hand,fabric thickness is an important factor which should be taken into consideration when making a garment.In order to sculpt a garment as anticipated,difference match designs on seams,such as flat felled or overlapped,are necessary.The bound edge or the blocking,and the difference for pattern matching are related with the thickness of material,the configuration of ready-wear and sewing craftsmanship.The difference matching design in apparel pattern can be divided into layer-overlapping type and turning-point type.
