I just finished teaching my first beginner knitting class
and several of the students are already interested in an intermediate class.
So...what do you consider intermediate? What do you consider advanced? Personally, I would consider lace and cables intermediate and intarsia and entrelac to be advanced, but that's just because I've had more trouble with the last two...lol.
Our beginner class got up to some shaping, so we did several types of increases and decreases, but thats as far as any of the felt they could go. The intermediate class would be in the fall, so they have the summer to practice (and I have the summer to teach another beginner class and get more people ready for intermediate!
