|yes, that's a black metal bed frame on the right...|
Each bag is one fleece (one sheep's worth). Raw weight (which includes all the dirt and lanolin) is approximately 2-3 pounds per fleece. Washing out the dirt lightens the fleece by a half pound. And if I had to guess, I'd say one fleece will spin up into about 800 yards of two-ply, sweater weight yarn.
Technically what I'm doing here is called "skirting." Skirting is the process of removing the wool from around the entire outer edge. This outer edge is the wool from the shoulders, belly and rump, and is typically the dirtiest. After skirting through all those fleeces, I got a pretty good feel for the quality of my flock. It became obvious which sheep had the longest fleece (Abner), which was starting to have a poorer quality fleece due to age (Knight and Mammy), and which one had the best coloring (Gretl's is gorgeous!). Lambswool is the first fleece taken off a young sheep. On our farm, sheep are sheared for the first time at one year of age. These fleeces are very long and much softer than adult fleeces.
