In our experience, beauty has very little to do with complexity. Complex things can be very beautiful, of course, but when they are, it’s only a coincidence. It’s just as likely that a simple thing will be beautiful, and in the case of our Mistake Rib Cowl, it’s definite!

The Mistake Rib stitch pattern is nearly as simple as knit 2, purl 2, but the finished fabric has a lovely loft and squishiness that regular 2 x 2 ribbing lacks. Purl Soho’s Mulberry Merino lends the pattern a particular depth with its gentle shine and richness. And in Dark Loam, our Mistake Rib Cowl is mysterious, lush, and simply beautiful! -Joelle
