Suzhou is famous for embroidery work, with silk as the main material. The Suzhou style has a history going back 2000 years and is considered one of China's four great types of embroidery. (The others are centered in Changsha, Chaozhou and Chengdu.) The Institute functions as a museum, as a workshop for modern craftspeople, and as an outlet for their products. Prices may be somewhat higher than elsewhere, but quality is high.
