Abstract: The Dechang Lisu embroidery patterns are rich in themes and exquisite in shapes, and the patterns are inspired by daily life with distinctive regional characteristics and cultural connotations. Combining the research methods of design and ethnology, and based on the first-hand graphic and textual data collected from fieldwork and interviews with the inheritors, this research analyzed and summarized the embroidery materials and techniques, pattern themes and modeling techniques, pattern compositions and color combinations, etc., and extracted the typical patterns for design transformation. Adhering to the concept of green development, the products were made of recyclable and safe biodegradable plant fiber synthetic leather. By combining innovative derivative patterns with embroidery and dyeing techniques, versatile and fashionable luggage bags are created. This research aims to explore the artistic design value and diversified transformation path of ethnic embroidery patterns in plant leather bags, and provide a new reference for promoting the development of Dechang Lisu intangible cultural heritage and the innovative practice of ethnic handicrafts.
