These garments and accessories are produced on hand-powered knitting machines in Scotland. All the pieces are fully fashioned, which means that each panel is knitted into its correct shape before linking it on to the next panel (rather than knitting a standard sheet of fabric then cutting and sewing it like a T shirt). To do this, the knitter has to manually hook and unhook the yarn after each line of stitching. For example, one stitch is taken off the panel at every line to produce a curved shoulder seam.
Finished panels are hand linked: the two pieces to be joined are lined up stitch by stitch onto a circular drum of knitting hooks, and then knitted together using the same yarn as the panels. Finally the seams are hand-tacked at each end to keep them safe, and buttons and trims are sewn into place.
