Yarn: The original yarn has been discontinued, but worsted weight Merino Cashmere Nylon yarns from Plucky Knitter, Madeline Tosh, and Malabrigo have worked beautifully, and many other dyers/companies make merino worsteds in subtly variegated colorways.
For a more rustic version, Hudson + West Forge, Cascade 220, Magpie Fibers Nest Worsted, or another wool in a solid, tweed, or heather works well.
If considering other yarns, you need a worsted weight fiber with an even twist in a solid or subtle colorway, without too much weight or drape. Look at the FOs on Ravelry to see how different yarns have knit up if you need ideas!
