Washed and dyed fleece.

Teased. I simply pulled it apart by hand. Here is the teased wool on my windowsill. You can see how it looks like a puffy cloud, pretty translucent.

And here it is all spun up. It has a slightly fuzzy surface, since the fibers were spun from the lock, and not combed or carded. I sometimes like this more "rustic" looking yarn.
If you're a spinner, I hope you'll try this technique. It's fun, easy and gives you another option to add to your repertoire.
