Circular reference hat and cowl are worked in spiraling two-color brioche. The pattern is enhanced by switching the main color and contrast color for each panel. Use high contrast in colors for a more visible pattern or less contrast for a subtle effect. This pattern will keep you interested while knitting and still produces a cool no-frills end result. Make the hat first, and you can adjust the size of the cowl according to how much yarn you have left. This unisex design works for both men and women. The pattern comes in sizes S and L. The stretchy brioche makes it adjustable for anything in between - or even for a child: my 7-year-old Young Warrior announced that he is taking the samples, because a silk-merino cowl is just what he needs as the weather is getting colder.
