The different fabrics you can create based on different repetitions, fibers, weights, solid colors versus variegated, tonal/hand dyed, and any combination there of, was mind blowing as well as inspiring. Again, I left raring to go (and swatch).
One of the great things I find in taking classes as well as teaching classes is the wealth information that comes out that does not necessarily have anything to do with your class content. It’s the kind of information that adds to (what I consider) a knitter’s mental toolbox of techniques. The kind of techniques that make your knitting easier. Little tips and tricks that we pick up along the way that empower us to modify patterns and infer knowledge when it is not spelled out.
