Qunmen is used to decorate dresses. Usually both the front and rear sides of a dress are decorated with a piece of qunmen respectively, to make the wearer look in better shape. This used to be popular among women’s dresses in Qing Dynasty. Acid blue satin with dark patterns is adopted as the backing materials embroidered with flowers and butterflies through applying layered stitch technique. Layered stitch is one of traditional Chinese stitching techniques; short straight embroidered patterns are placed in order from outside to inside, and along the patterns, they can be layered through straight stitch technique, with all the layers linking up in turn. Layered stitching from the outer edge to the inner is called forward layered stitch, and reverse layered stitch the other way round. There is a gap left at each stitch point between the layers, called “waterway”. It is a decorative technique specially used in layered stitch works. This piece of layered stitch work is constituted by various blue colors, dark or light, and thus called “three blue color layered stitch work”. The flowers and butterflies look lifelike in bright colors; these decorative patterns are compactly arranged, which is what we call “background totally hiding behind the patterns”.
