Su embroidery, in its own terms
China's current national standard defines Su embroidery as hand needlework centred on the Suzhou region, worked with dyed pure mulberry-silk thread on silk or related silk grounds, in single- or double-faced pieces made either for viewing or for use.
This page is an introduction to the tradition rather than to our shop: the official record, the history that survives in actual objects, the technical vocabulary, and the people who carried it. Every claim below is drawn from the national inventory, the current product standard, or the institute named as the project's protection unit.
The official record
Su embroidery was inscribed by the State Council of China, not by UNESCO. What follows is the wording of the national inventory itself. It describes a tradition — not any single workshop, brand or product.
The same project number also covers four regional branches inscribed as extensions: the random-stitch embroidery of Changzhou, the embroidery of Yangzhou, the simulation embroidery of Nantong and the fine-miniature embroidery of Wuxi.
Alongside the inventory, the product standard GB/T 38029-2019 has been in force since March 2020 and remained valid at its most recent review.
A history visible in surviving work
The official heritage record is careful: the origin of Su embroidery is unknown. Surviving works from the Song period onward show its development. A Yuan fragment already combines nine stitch methods; Ming embroideries often followed literati painting and developed the fine, restrained character later associated with the tradition; by the Qing period, Suzhou supported a flourishing commercial embroidery trade.
It is also a written tradition. During the Daoguang reign a Suzhou woman, Ding Pei, summarised the techniques of the needle in the Xiupu — recorded as the first specialist book on embroidery in China. Shen Shou dictated her own manual late in life, setting down the experience of a working embroiderer rather than the admiration of an onlooker.
Three lineages still carried
Many local variants have existed. The heritage record singles out three schools as having clear inheritors and lasting influence — which is also why Su embroidery is described as a living practice rather than a fixed antique technique.
Traditional fine embroidery
Described by the protection unit as arranging the needle in close ranks and joining the lines densely. It carries the classical subjects — flowers, old landscapes, figures — and is where the qualities of evenness, fineness and lustre are judged.
Simulation embroidery
Created by Shen Shou around the turn of the twentieth century. Absorbing Western pictorial art, she used turning and solid-and-void stitches to render the texture of things, so that colour reads as naturally graded. Portraits were its strength.
Random-stitch embroidery
Created by Yang Shouyu in the 1930s. Straight lines of different directions and colours are crossed and layered to build volume, space and shifting colour — closer to painting with the needle than to filling a drawn outline.
Eight words
The protection unit sums up the character of Su embroidery in eight single words. They are not marketing adjectives but the terms by which embroiderers judge a finished surface.
平 · ping
the embroidered surface lies flat
齐 · qi
edges of the motif are ordered
细 · xi
fine needle, fine thread
密 · mi
lines sit close, without showing the stitch
匀 · yun
spacing stays consistent throughout
顺 · shun
the thread direction turns freely with the form
和 · he
colour is set in agreement
光 · guang
the silk holds its lustre
Thickness is a decision, not a boast
Su embroidery counts the thickness of its thread. Half a floss thread is called one rong; a twelfth of one is called one si. Splitting — bisi — is the act of dividing a floss thread into these finer parts, chosen against the ground fabric, the colour and the subject.
The protection unit explains it through examples. For the tail of a goldfish the thread is thin and the stitches left open, so the fin reads as thin and translucent; the body takes slightly thicker thread set densely, so it reads as solid. Stones and old branches want thick thread and deliberately uneven stitching. For a cat, the embroiderer follows the way the fur actually turns, and the animal comes out soft to the eye.
A frequent misunderstanding: finer is not automatically better. Suzhou's public records cite demonstrations in which one thread was divided into as many as 128 parts, but that is a display of skill, not a specification that every piece should meet.
Two faces, one ground
In single-faced embroidery only the front has to be right; the path the thread takes across the back is nobody's concern. Double-faced work removes that hiding place. One pass of the needle has to produce the same image on both sides, and both faces must be equally ordered and even.
Same image, same colour
The base case: one ground, one stitching pass, an identical picture in identical colours on front and back. The protection unit dates the first double-faced work to its own studios in the 1960s.
Different colour, then different image
Embroiderers went on to make the two faces differ in colour, and then in colour and image together. The screens below are of this kind.
The three differences
In shuangmian sanyixiu, corresponding areas of the two faces differ in image, in stitch method and in colour at once. The protection unit records it as without precedent in the history of Chinese embroidery.
A contemporary double-faced table screen in different colours — 双面异色绣 · one silk ground, one stitching pass, the same cat ginger on one face and silver-grey on the other · used with permission
We carry double-faced screens of this kind — pieces you can turn on the table and read twice. Search the collection for double-faced, or by subject: cat, panda, peony.
Whose hands
For most of its history this was women's work, done at home and in workshops across the Suzhou region, and at times for the imperial court through the city's state silk manufactory. The research institute founded in the 1950s gathered and trained embroiderers in numbers, and new stitch methods were developed there on top of the inherited ones. The record is not anonymous: every representative inheritor the state has named for this project is a woman, listed with her date of birth.
A Suzhou woman of the Daoguang reign who summarised the techniques of the needle in the Xiupu, recorded as China's first specialist book on embroidery.
Created simulation embroidery in the late Qing and early Republic, and dictated her Xuehuan xiupu late in life to record what she had learned. Her method continued in Nantong, now separately inscribed under the same project number.
Created random-stitch embroidery in the 1930s, bringing the logic of painting into the logic of the needle.
Born 1931; named in the first group of national representative inheritors for Su embroidery. She wrote a study of its stitch types and working methods in 1955 and founded the China Suzhou Embroidery Art Museum in 1986.
