Lambswool is wool obtained from a young sheep's first shearing, producing fine, soft fibres with a naturally springy handle. It is warm and breathable and is commonly used for knitwear, coats and other cold-weather garments.

Cable knit is a knitted construction featuring raised, twisted or braided motifs created by crossing stitches. The cables form a distinctly three-dimensional surface and are usually set against a flatter knitted background. It is particularly common in substantial sweaters and traditional knitwear.

Founded in Britain in 1970, Jigsaw combines contemporary design with an emphasis on craftsmanship and quality fabrics. The brand works with its own atelier and produces many collections in limited runs, with a focus on distinctive pieces rather than high-volume fashion. Jigsaw also has a longstanding connection with British arts and culture through its Art Foundation.
