Still Spinning

I checked out a copy of Anne Field's Spinning Wool: Beyond the Basics (thank you interlibrary loan!) and it isn't as helpful as I hoped.  I am not really sure what to do with the yarn.  I can't match how I spin with the methods she dscribes, and I'm a bit paranoid that I'm doing it wrong and I have bad habits that will limit me later.  However.  My yarn continues to be more consistent as well as less over spun.  I'm just a bit worried that now it is underspun, but I think I just made that it.  I don't have pictures yet, but the latest I spun appears to be about sport weight, and appears balanced after plying.  I haven't experimented more with art yarn.
