The sweater, with the colors of ashes, is named after Fimmvörðuháls, a mountain pass in Iceland at the site of the now-famous eruption of glacier Eyjafjallajökull in 2010. I knitted the sweater while walking this pass, in my Hiking and knitting tour between Fire and Ice in the summer of 2011. It is typical of an Icelandic lopi yoke sweater, but also seeks inspiration in the Old costume jackets (close-fitted shaping and unusual elbow shaping) and the Icelandic lace shawl tradition: the colorwork in the yoke is faked with a typical undulating lace pattern and the crocheted chain bind-off adds a feminine touch.
The cardigan version, using Cascade yarn, is either knitted in the round and steeked, or knitted back and forth, then a crochet edging with button loops crocheted as you go added. Sample shown with reindeer horn buttons made by Icelandic artisans.
