How much Fiber do I need? These amounts are estimates.
Design, thickness of yarn, size will effect amounts. Best to
overestimate.
to spin for a pair of socks 4 oz.
for a average size adult vest 16
oz.
for a average size adult sweater
24-32 oz.

Other Breeds/types of wools that I have used
that have felted well: Falkland, Colonial.
Mohair with sheep
wool and Angora rabbit. Always test felt a
swatch.
Even though Shetland rates lower in feltability, it
does felt, just may take longer. 5 * indicate maximum quality.

Terms
indicating How Fiber is Processed for spinning into yarn.
Top - fiber that has been combed. Fibers are
all parallel and will spin into a worsted yarn, smooth and firm.
Comes too thick to spin as is, so will need to pre-draft, best to
stretch this out more and NOT strip it. Stripping can change the
layout of the fibers and you will not get a true worsted yarn if you
do this. If you wish a semi-worsted yarn, some with a bit of loft,
OK to strip into sections. Or try spinning on the fold, break off
about 6", split apart and spread out fibers over your finger and
spin on the fold. Combed top is wonderful used in Fiber blending or
Color blending. White will lighten any color. Black will darken. Add
a bit of wool to mohair to give it some memory for knitting yarn.
White silk or Tencel in color blends will strengthen, soften and
highlight your fiber.
Roving - a batt that has been stretched out
and made much thinner or like pre-drafted fibers. Little or no
additional drafting required. Results in a semi-lofty yarn. This
type of fiber put up made by larger commercial machines.
Rolag - wool carded on hand cards and then rolled up into a
sausage
shape. Spin from the end of the sausage. Results in a lofty yarn.
Batt - wool carded on a drum carder and when it is pulled off
it is in a
flat rectangular shape. Generally rolled for storage. To spin,
unroll and strip lengthwise and spin from the ends. Results in a
semi-lofty yarn.
Sliver - another form of thin processed combed fibers.
Pencil Roving - a very thin roving &/or combed top, usually
about the thickness of a pencil.
Superwash fibers have been treated with a polymer
coating, laying down the wool scales that cause shrinkage and felting.
These wool yarns feel smoother or slicker. A garment crafted with
this yarn can safely be washed in the wash machine on the gentle cycle.
Lay flat to dry rather than using the dryer. Natural fiber shampoo
is recommended, such as
Wool
Wash.
Blood System:
It was agreed upon by breeders that Merino fleece was about 2 1/2 inches
long and the fiber diameter was very fine and the crimp was very small
and close together. This set the standard for comparison and it
would be called "Fine". Results, if you bred a Merino to some other
non-Merino sheep the offspring would be half Merino, and you would
expect that lamb's wool to have half the character of the Merino fleece.
Further, since most other sheep have longer, coarser wool than Merinos
do, you would expect that half of the character of that lamb's wool
would also be longer and coarser. So, what you would get is called a 1/2
blood fleece and you it to have a larger fiber diameter than Merino
wool, a somewhat larger crimp, and a longer staple length. Then,
if you crossed that half blood lamb with another sheep the offspring's
wool would be called a 3/8ths blood fleece, and so on.
English (Bradford) Spinning Count System.
It is the number of hanks of yarn, each 560 yards in length, that it is
possible to spin from one pound of clean wool. The finer the wool fiber,
the more hanks (greater length, thinner yarn) that can be obtained from
one pound. Comparison is an approximation, there can be some
differences within the breed from animal to animal.
Microns is the measurement of the wool under a microscope.
