I got Intentional Spinner book from the library, but didn't get a chance to really go through it entirely before I had to return it. But it looked interesting. There's a few chapters about fibers and how to spin (all pics are on the wheel, no spindle pics) and about plying. There was a good description of worsted vs woolen and the variation in between. The part I didn't get a chance to look at was the project sections and the details about adjusting the wheel, instead of your treadling/drafing speeds. When I have some more time, I'm getting this again to study those sections.
The pooling scarves at Yarn Floozie are amazing. I have a skein of Anne yarn in beige shades that might work with this kind of pooling scarf.
