Black embroidery is one of the traditional stitching techniques from Zabol (Sistan and Baluchestan province), Shah Kuh (Golestan province), and Kalateh Rodbar (Damghan). It stems from the creativity and taste of the women of these regions and is executed beautifully using black thread on white fabric, incorporating exquisite patterns. In each region of Iran, particularly the areas studied, black embroidery reflects the beliefs and thoughts of the artists, their surrounding world, and their needs. This research aims to recognize and understand the visual and conceptual characteristics, as well as the factors influencing the formation and structure of black embroidery patterns in these areas, seeking to answer the following questions: 1- What are the patterns used in the black embroidery of the mentioned regions? 2- What are the factors affecting the formation of the traditional black embroidery of Zabol, Shah Kuh, and Kalateh Rodbar? The methodology of this research is descriptive-analytical, and the data collection involves library research as well as fieldwork, including photography and interviews. The results of this study indicate that black embroidery, as part of the culture and society of Zabol, Shah Kuh, and Kalateh Rodbar, employs designs and motifs that, while initially appearing as geometric shapes, curves, and broken lines, are symbolically inspired by nature, beliefs, customs, and traditions. These patterns encapsulate the local culture and identity of the region, where the talented women express their thoughts, emotions, and experiences through traditional stitching. By widely using plant, animal, abstract motifs, and their repetition while creating balance, they not only enhance the beauty but also ensure the sustainability of this art
