The Vikings - A History Lesson
Here is the link to a stunning article about the Vikings and wool. The story is about a group of Norwegian students from the Fosen Folk High School in Rissa, Norway who are learning the skills to survive in Viking times from raising sheep to making sails to sailing a ship much like the Vikings used. It's a bit long but a great read!
