Koginzashi is old needlework technology passed down in Tsugaru district. The origin of this technology is that in the Edo period farmers were forbidden to wear padded garment, so they dressed in several layers of clothing made of linen or ramie that grew in mountains to shut out the cold. In order to make the clothes more durable and warmer, the women began to give embroidering especially to the part of the shoulder, waist and lower sleeve edges with undyed cotton thread. It was the fruits of the women’s wisdom to overcome the severe cold in the northland. Koginzashi is characterized in that hand embroidering with white cotton thread is given along the weave patterns of indigo-dyed linen. At the present day, cotton or wool is also used and there is a variation in color. Its simple and beautiful geometrical patterns represent the strength and sensibility of the women in the northland, who carry on delicate needlework. It was designated as a traditional handicraft by the prefecture.
