Description from Wrap Style:
Nancy Marchant lives in Amsterdam where knitters are as familiar with brioche stitch as they are with ribbing. It was only natural, then, for Nancy to choose a brioche rib pattern for her capelet design. To add color interest to the strong linear stitch texture and give the fabric a shadowy effect, she alternates dark and light shades of a rich plum color. Nancy works the piece from the neck down and shapes it with accentuated increases along the shoulders.
