What kind of technique is 'herasi' mentioned in knitwear descriptions?

Herasi refers to narrowing, which shapes knitwear by decreasing the number of stitches. Unlike garments where woven fabric is generally cut along patterns and sewn together, knitwear allows curved shapes to be formed by adjusting the number of stitches during the yarn-interlocking stage.

AMOMENTO applied this technique to the neckline and armhole areas of the Cashmere Easy Half Sleeve Knit^[1][2]. By knitting so that stitches are sequentially decreased along the curves, the garment's outer silhouette was neatly refined^[3]. The seams at the joints were also connected with linking stitches, finishing them for a comfortable, snag-free wear^[4].

The weave itself becomes the curve. Because it reduces the thick seam allowances that occur when fabric is cut with scissors and sewn together, the stitched areas touching the skin do not irritate, and the shoulder and necklines fall smoothly.
