I have been lately. My friend is looking into buying her first spinning wheel and I've been trying to share some of my knowledge (limited as it is) with her. So I figured I would also put together a post with some of the references that I have used over the last year.
Stitch it! Podcast - Meghan share a wealth of information on spinning, some of which she picked up at SOAR last year.
This video about the different drive system set ups. I do not have a Schacht, but I do have a double drive wheel that I can set up in these different ways. Can't wait to try the Irish drive set up.
Sit and Spin DVD - great art yarn DVD
Spin Control book - great book with a large amount of info
...and lots of YouTube videos. That's all I can think of right now.
