The history about norwegian sheeps and the wool 

Our history of using wool has long traditions in Norway. We estimate that we have had sheeps in the country for at least 5,000 years. The Vikings were good at using the sheeps. And nothing went to waste. They were given food on the table, and clothes to wear. But perhaps most important was weaving sails for their ships. They set sail on the ships. It made it possible to travel far away.

In the Viking world, the sea, fjords and rivers linked people together, while mountains and forests separated them. Therefore, the Vikings were great shipbuilders, and they valued a good ship. They used and made vessels that could be sailed and rowed. A sail required great quantities of valuable wool as well as labor to make woolen thread and fabric. A good sail was just as valuable as the ship itself. The Vikings were also good at dyeing the wool yarn with plant colors.
