Here I am in my Viking costume. It is a work in progress. I really need a headscarf, a belt, and another layer. I made the apron using this pattern. It is based on the Birka style. There is very good information about Viking dress here, and a bunch of links here.
I've got brooches holding up the apron, a pin of the Norse god & goddess Frey & Freya, a key, and my newest addition, the necklace.
Our Daughters of Norway lodge made them, as well as earrings and bracelets, to sell at Norway Day. The member who led the project researched Viking jewelry, and the designs are based on a necklace found at Hon, Norway. There is a picture of it on the Viking Answer Lady's jewelry page.
