cloud-like, wispy, and high in price.

Johnstons of Elgin, a company

that has been making cashmere products since 1851,

gave us a peek inside the cashmere-making process.

Here's how cashmere is made.

This prized material stems from the cashmere goat

and is also almost three times

more insulating than sheep wool.

These goats can be found across the Himalayas,

and they're very in-demand.

In some cases, several goats are needed

to make just a single cashmere garment.

- So cashmere is very precious, and it's collected

in very small quantities.

It's combed from the underside of the goat

in a very natural process at the springtime

when the fibers are starting to float,

so they're shedding their winter coats.

Narrator: First, the fibers are dyed

to the desired color.

Johnstons of Elgin has over 6,500 shades

in its color library.

Dying can leave the fibers matted,

so teasing helps open them.

Here is where the cashmere is blended

with other colors or other fibers.

Fibers can include Merino wool or silk,

so sometimes cashmere can be blended

with different colors but have the same fiber,

or they can be of the same color

and be blended with different fibers.

From there, the cashmere is fed into a carding machine.

This machine detangles and combs the hair

into thin sheets known as rovings.

This process has barely changed since the 1800s.

- Every single stage is within our control.

If something goes wrong at the end of the process,

we can go right back in the process

and understand what caused that.

And, of course, when we're working

on the very highest luxury level, we can perfect things,

so we can do things that other mills just can't do.

Narrator: Next, the rovings

are uniformly spun into yarn.

Spinning twists the fibers together,

which helps give the cashmere its strength.

At Johnstons of Elgin, the yarn is regularly checked by hand

to make sure the consistency is even.

The weaving part of the process lays out

the pattern of the cashmere garment.

The color, pattern, and design of the weave

is decided in advance.

The warp, a basic component used in weaving

to turn yarn into fabric, consists of the threads

that run from the top to the bottom of the cloth.

Cashmere is a very versatile fabric.

It's extremely lightweight and comfortable,

keeping you warm in the cold and cool in the heat.

The cashmere is carefully washed.

Johnstons of Elgin uses water specifically

from the River Teviot.

This is to help bring the fabric back

to its original soft state.

The trim is then cut, and a label is stitched on.

Although cashmere is a delicate fabric,

if cared for properly, it can last you a lifetime.

So next time you're wearing your favorite cashmere scarf

or sweater, you'll now know what makes this material

so unique and luxurious.
