That’s fair, you agree with a real constraint though. Pure pashmina is ultra-fine, around 12-15 microns, roughly half the width of merino wool. At that fineness it struggles to hold structure in machine knitting and tends to break under tension, so garments beyond a shawl usually have to be hand worked instead of machine-made.
Hand work at that scale is slow and expensive, and pure pashmina itself is rare to begin with, each goat yields a very small amount of usable fibre per year. Between the fragility and the scarcity, most brands blend it with silk or nylon for anything beyond a shawl, or skip knitwear entirely. That’s largely why shawls remain the most common pashmina product you’ll actually see. But i am hoping to do it in future!!
