Our wool is exceptionally clean because we require extra steps to sort through grease wool before sending it off to be scoured (washed). Skirting, grading, and baling the wool helps us to retrieve only the finest natural fibers for our customers.

Skirting

Once the fleece is removed from a sheep, it’s passed to a skirting table. At the skirting table, dirtier parts of the fleece from the sheep’s belly and rear are removed. This less desirable wool is put aside and sold for different purposes.

At this point the wool is called “grease wool.” Grease wool is still quite dirty and greasy with lanolin. Lanolin is the oil that sheep produce to protect their skin and make their coats waterproof.

Grading

The grease wool is also “graded.” Wool grade is determined by fiber thickness and the amount of debris in the wool. This information helps buyers purchase the correct quality and type of wool.

There are three major grading systems that have evolved over the years:

• The Blood System is the oldest, originating at the time of the early American colonies. It is based on the bloodline or breeding of sheep.
• The Count System is more extensive and involves the number of “hanks” of yarn that can be spun from one pound of wool. A hank is 560 yards.
• The Micron System is the most technical and accurate system of grading. This system separates wool into grades according to the average fiber diameter as measured by a micrometer.

We use the Micron System almost exclusively. Our batting is comprised of several micron ranges and staple lengths. By blending the fiber this way, we are able to create exceptional resilience and loft.

Baling

Skirted and graded grease wool is then stacked and pressed into bales for more efficient shipping. Each bale contains about 500 pounds of grease wool from up to 100 sheep.

Once all the spring clip is sheared, skirted and baled, it’s collected at our facilities and labeled for transport.
