I started out raising a mixed flock of sheep with Corriedale, Clun Forest, Border Leicester X and Icelandic sheep. I became familiar with those types of wool, and through shearing sheep for others, also became familiar with a wide range of wool types.
As a wool buyer, I don't turn down any fleeces, because I love them all and find a purpose for each wool type that I take. One of the wonders of wool in the 21st century is that, among other attributes, it is versatile and regardless of the fineness or coarseness, it all has a place in the value added product marketplace.
Finn wool, ranges from animal to animal, from fine and crimpy with a medium staple length, to britchy, straight and course on some animals. Hand spinners in the USA are only now becoming familiar with this lovely, high luster wool. In some places a good, clean fleece, free of any hay chaff, burrs, dirt etc. will bring upwards of $20.00 per pound.
Finnsheep come in a variety of colors and it appears that breeders everywhere are concentrating efforts on understanding and producing consistent colored fleeces. While spots, stripes, and many different patterns and markings are possible, white still remains the best for dyeing. White fleeces also carry high luster giving a sheen to the finsished yarn that rivals mohair. Less true for colored fleeces.
When looking at a Finnsheep for wool quality, its important to check for uniformity in the fleece, from shoulder to tail. Often there is a "britch" wool on the hind legs that becomes course and straight. Many hand spinners will toss this as garbage, some will blend it, others will separate it, mix with similar, and use it for rugs. It all depends on what you want your final product to be.
One sure way to know the wool quality of your animals is to send a sample of the fleece to Yocum-McColl who will test it and send back a full report. Often this report is surprising, contrasting with the subjective analysis that results from touching, feeling and seeing the wool.
A fine Finn fleece would be one of 26 micron count, which is, according to Yocum-McColl, the equivalent of Merino wool.
A point to remember is that as a sheep ages, their wool tends to become more coarse. Most of us are aware that a lambs fleece is very, very soft and will be the softest of any fleece the sheep will have in the future.
Wool is a sustainable, renewable and earth friendly product. Sheep grow new wool each year, and depending on the breed, may give two fleeces/ year though most are shorn only once annually, and this in the early Spring prior to lambing.
Wool is coated with lanolin which the sheep produces through numerous glands on its skin. The lanolin content differs according to breed, with some having little lanolin, others having so much that simply handling the fleece covers your hands with it. This is usually referred to as "grease" and wool that is raw, not having been yet washed, is called "grease wool." Back in the day, wool was spun raw with the lanolin still on it and this gave rise to the term, "spinning in the grease."
There is some mixed info on whether or not leaving the lanolin on the yarn as it is spun will afford any water repellent qualities to the finished product. If I were to guess I would think that as long as the garment or textile isn't ever washed that degree of water repellence will remain, but once exposed to wash, will be removed. Just my guess.
I have spun in the grease myself, and enjoy handling wool with the higher degree of lanolin. When skirting raw fleeces with high lanolin content the lanolin will give the feel of a much softer fiber than truly exists, and this can be misleading. Once that wool is washed the true coarser nature is obvious.
Finn wool has a soft, almost silky feel to it that is quite noticeable in the finished yarn. This makes it a good wool for items that come in contact with one's skin where softness is appreciated.
Finn fleeces average somewhere around 6 - 8 pounds in my flock. Having shorn sheep that yield 12 pound fleeces, this doesn't seem like a lot per animal, but in a flock of 30 animals its 180 - 240 lbs of wool, which needs to be skirted, picked, washed, carded and spun. Plenty!
Finn fleece is pleasant spun raw, or from processed rovings, and it felts nicely making it a versatile wool for most fiber artists.
