I don't really have anything to add to the technical side of it, but I remember my mom's reaction when I first told her about my plans to try felting as part of my knitting project.
My mom was the one who taught me to knit many years ago, and she used to knit all sorts of sweaters and dresses and hats even before I was born. When I (foolishly) asked her if she knew what "felting" meant, she laughed and said, "Yes, I know what felting is, but I used to call it 'fulling' and I never did it on purpose. It was what happened when I accidentally threw a wool sweater into the dryer."
