Just in case you're interested, here's a comparison of the Rambouillet x Cormo wool before and after washing. These are two halves of one large lock, so they started out the same size. As you can see, there was quite a bit of take-up in the staple length after washing, as well as a lot of fluff-factor! The fibers are so springy, if you stretch out the crimps, they are still the same length.
And here's a shot of the rewashed fleece, carded with dog brushes and attenuated into roving. Lovely stuff. The second wash did the trick, and the wool drafts like a dream now.
I continued to spin on the Merino/tussah last night, and thought I was going to be able to finish the premeasured pile of roving, but at 10:00, I was too tired and had to go to bed. Tonight for sure!
