Have you heard of viking knitting before? Well, I haven't. If you'd asked me I'd suggested something like those chain mailles shirt that are formed with lots and lots of single rings that are sort of woven into a "fabric". But it turns out that viking knitting or trichinopoly as it is called as well is a lot more like "real" knitting, I found these two videos in my youtube suggestions area and thought I'd share as I really like the formed necklaces and bracelets.
