Gauge as the governing variable
Stitch and row count per unit determines a knit garment's size, drape, and yarn consumption, so gauge is fixed before design proceeds. Every measurement downstream is expressed in stitches, not inches.

The manual catalogs stitch types (jersey, rib, cable, intarsia, jacquard) and the properties each imparts to a fabric. Choosing a structure is choosing stretch, thickness, and pattern capability at once.
A knitwear tech pack encodes measurements, yarn, gauge, and construction so a mill can produce the garment without the designer present. Ambiguity in the spec becomes defects in the run.
