In this pattern, every YO shows up as knit, YO, SSK. But sometimes I was wrapping the YO front to back, and sometimes back to front - it's amazing the variation possible, whether you mean it or not! But your description is the first I've seen that makes sense. A lot of them say things like "wrap the yarn counterclockwise" and sometimes just "wrap the yarn around", and I just never knew what to do.

A knitting tutorial at Pennsic would be fabulous!
