Cormo is a breed developed by crossing corridale and merino sheep. So it has many of the same characteristics as merino and is a very soft wool. It's harder to home process because of the higher lanolin, but wonderful to spin, especially in the lock.
Here's a photo of the locks from my breed sampler file:
I talk about how I like combing the cormo better than carding and that after combing I pulled some fiber through a diz and spun that. I also spun fiber straight from washed locks and I found that my singles from both methods were spinning to about the same WPI.
Here's a picture of two ply, combed and lock spun. Just like merino there's lots of bounce to the yarn.

The second breed of sheep I talk about is the Montadale, not a fleece most spinners will get to try unless they have a local shepherd raising that breed of sheep. It is a down sheep breed and is used for both meat and fleece. This means that the fleece is not a soft fleece, although it is certainly OK for socks by my standards and therefore probably sweaters too.
