I wanted to design a cozy, warm pullover for winter that would be a modern take on traditional Scandinavian style. The pattern uses a thick, cushy yarn—to make it quick to knit—and one simple band of patterning for minimalist Norwegian style. I chose rolled edges for their casual look—a concealed bit of ribbing controls the roll. Dropped sleeves and a straight body add to the classic silhouette. The tracings of dark lines across the natural color reminded me of the trunk of a birch tree, hence the name. This is a great pattern to try colorwork for the first time or to whip up as a quick gift!
