About Viking Knit:
Nearly 1,300 years ago Vikings used long pieces of silver and gold wire to weave ropes. These woven wire ropes were then stretched and made into jewelry for famous and powerful Viking leaders. This wire weaving is called Viking Knit (or trichinopoly chain.) Modern artist are now calling it Viking Knit.
