The embroidery of Guimarães is a delicate and rigorous work of cotton thread on homemade linen, a feminine craft, which has evolved from the popular embroideries used in traditional costumes. The originality of this embroidery, one of the oldest in Portugal, is the amount of a specific needlework called "purl", which is a very fine thread curled in a spiral, in relation to the enormous diversity of needlework used and the singularity of the geometric drawings of floral inspiration.
