Leather products, as a significant component of modern fashion, have a wide range of market demand. To address the issues of traditional patterns in intangible cultural heritage not matching modern aesthetics and lacking application scenarios, this study takes leather products as carriers and proposes an innovative design paradigm for traditional clothing patterns. We chose the Miao cross-stitch patterns of Guizhou, China, as a case study. Analyzed their subject connotations, common structures and features. Using split grammar and shape grammar, the patterns are deconstructed and reassembled to obtain foundational innovative patterns. The Mean-shift clustering algorithm was applied to extract the classic colors of Miao cross-stitch patterns. Based on fractal theory and computer algorithms, a novel pattern model for Miao cross-stitch was proposed, incorporating representative patterns and colors to complete pattern designs. Finally, the feasibility of the proposed approach was validated through the practical design of leather fashion accessories on the Style 3D platform. This study aims to provide methodological references for the modernization and innovation of intangible cultural heritage, as well as the diverse integration of leather products design.
