This is the downy undercoat that some goats grow in the wintertime.  It has a short
staple length, is a fine fiber that likes to be spun fine, making it a great charkha fiber.  
There is no such thing as a cashmere goat and many meat or dairy goats can produce
cashmere.
This home grown cashmere comes
from my mom's goat, Sassy, a black
alpine cross goat with attitude.  She
loved to be combed last year, and
gave me about an ounce of this
beautiful grey cashmere.

I was told by someone who raises
goats for their cashmere that this was
not of good quality and I would never
be able to spin it.  It was a little
difficult to spin because of a shorter
than average staple length, but
produced a beautiful yarn that is very
soft.
This is Sassy, the goat the above
cashmere came from.
Bombyx silk adds some sheen to
this blend without taking away the
softness of the cashmere.  This
blend spins fairly easily into a fine
lace weight yarn.
This blend shows off the natural color
of soy silk, so I suspect white
cashmere was used in this blend.  It is
an easy to spin, soft blend, that will
most likely dye up wonderfully.

I am partial to naturally colored animal
fiber, so I like the cashmere/silk blend
above better, but this blend also makes
a beautiful yarn.
