There can be no confusion: winter has arrived. Helping welcome it in are the first items of knitwear from Book No. 1: two moss-stitched crewneck jumpers, knitted in Nottingham using Shetland Isle yarns.

Two colours: grey and navy. They have been knitted by a family-run Nottinghamshire factory, and the number of each can be counted comfortably on the fingers of one hand.

The Shetland Isle yarn has been spun using equipment and techniques employed by the mill for two-or-so centuries, providing a decidedly heavy gauge. Careful hand-twisting and light oiling of the yarn, meanwhile, softens up its characteristically chunky handle.

Save for the knitted inset pockets, which sit at hip-height on the side-seams, and the thicker-than-average tubular ribbed crewneck, the jumpers go largely unadorned — better instead, this time around, to let the material and the stitch speak for themselves.
