This sweater can be found in Lily Chin's book, Power Cables.
This stole demonstrates yet another reversible faux cable. Instead of crossing sets of stitches over one another, the rib stitches placed on a cable needle on a cable needle do a 180° turn. The brushed baby alpaca yarn makes the piece weightless yet warm. Work fewer repeats of the stitch pattern for a smaller scarf-sized version or make a larger version for a whole afghan.
