For the first class I am teaching in June, 2 hours long, I hope to mention how eco-friendly wool is (sheep are not harmed in shearing); and cover some aspects of color theory while emphasizing that this is only the beginning of our wool journey not the end by any stretch of the imagination.  Since I am also planning on the students dyeing some wool and having a blast this is a lot to cover in just 2 hours.  A lot of preparation has gone into this class, so wish me luck!
