A technique producing a vertical, textured fabric, it alternates knit and purl stitches. This alternation creates a series of vertical columns, resulting in a stretchable and resilient fabric ideal for edges and fitted garments. For instance, a common application is along the cuff of a sweater, providing both elasticity and a neat finish.
Its importance stems from its ability to create form-fitting edges, prevent curling, and add visual interest. Historically, it has been a practical choice for creating garments that move with the wearer, offering both comfort and durability. The structure enhances the garment’s ability to retain its shape after repeated wear and washing.
