Cusco and the Sacred Valley Feature

Vendors and hole-in-the-wall shopkeepers will beckon you in to look at their wares: "One of a kind," they proudly proclaim. "Baby alpaca, hand woven by my grandmother on her deathbed. It's yours for S/70."

Price should be the first giveaway. A real baby-alpaca sweater would sell for more than S/200. So maintain your skepticism even if the label boldly states "100% baby alpaca". False labels are common on acrylic-blend clothing throughout the Cusco area. Which brings us to our next clue: A good-quality label should show the maker's or seller's name and address. You're more likely to find quality goods at an upscale shop, of which there are several around town. Such a business is just not going to gamble its reputation on inferior products.

Texture is the classic piece of evidence. Baby-alpaca products use hairs, 16-18 microns in diameter, taken from the animal's first clipping. Subsequent shearings from a more mature alpaca yield hairs with a 20-micron diameter, still quite soft, but never matching the legendary tenderness of baby alpaca. (For that reason, women tend toward baby-alpaca products; men navigate toward regular alpaca.) A blend with llama or sheep's wool is slightly rougher to the touch and, for some people, itchier to the skin. And if the garment is too silky, it's likely a synthetic blend. (The occasional 100% polyester product is passed off as alpaca to unsuspecting buyers.)

While "one of a kind" denotes uniqueness—and, again, be aware that much of what is claimed to be handmade here really comes from a factory—the experts say there is nothing wrong with factory-made alpaca products. A garment really woven by someone's grandmother lacks a certain degree of quality control, and you may find later that the dyes run or the seams come undone.
