“Named for a genus of large, long-winged moths (inspired by the Peppered moth: Biston betularia), Biston is a relaxed cocoon-style cardigan that makes an easy layering piece for any season. The garment is a relaxing project – knit flat in one piece – that allows the tweedy nature of Loft to take focus. The textured band features a slanting rib that radiates out from the center back neck to contrast with the body’s reverse stockinette fabric.

Biston is a relaxed, unfitted shape through the main section of the body, with a close-fitting cuff on the 3/4 length sleeves. Fitting Notes have been provided below to aid you in choosing your size, or in making your own fit adjustments.” – Mercedes Tarasovich-Clark


  • Garment is knit flat in one piece from cuff to cuff.
  • Upon completion of knitting, body is folded in half lengthwise and seamed along sleeve edges.
  • After seaming, the textured trim is picked up and worked circularly around body opening.
