Wadmal (Old Norse: vaðmál; Norwegian: vadmål, 'cloth measure') is a coarse, dense, usually undyed wool fabric woven in Iceland, Norway, Sweden, Denmark, Greenland, and the Orkney, Faroe and Shetland Islands from the Middle Ages into the 18th century.
[4] Wadmal was the main export of Iceland, where length, width, thread count, and weight for different grades were fixed by law.
[4][7] According to archeologist Michele Hayeur Smith, wadmal was significant enough in Iceland “that its production nearly eliminated other textile types from the island’s woven repertoire.”[4] Some have argued that,[who?]
given the importance of wadmal in Iceland and the fact that women primarily produced it, that gender relations in Iceland may have been more equal than was previously thought: "making vaðmál was making money and this may have provided women with a source of power that was socially understood, as the weavers knew best the differences between good and poor-quality vaðmál.
This seeming symbiosis may stem from the small size of the Icelandic colony, the harsh nature of the North Atlantic environment and the need for collaboration between the sexes to guarantee survival.
