Hi MsMae,
You are correct - there is a learning curve for every new activity we take on and spinning is no different

I had a very hard time learning to use a wheel because I'm not a very coordinated person and had a terrible time getting everything to work together.
Judith McKenzie-Mc Cuin's first book "Teach Yourself Visually: Handspinning" is a better book for a beginning spinner as it focuses on using a spindle and wheel, adjusting your wheel, and actually learning how to spin yarns. "The Intentional Spinner" doesn't cover the very basics of spinning but adds much to the basics to enable the spinner to have fine control over the yarns produced. I highly recommend both books.
Wool/cotton blend? Not good for learning to spin! I'm surprised that the teacher did not have some good fiber available for beginning spinners to use. Romney wool is very good for learning to spin.
