Thanks for the reply, I guess it's safe to assume - all of my "knit rows" are actually "knit in back" rows. I've only been doing this 30+ years.
Do you know of an image available on-line where I can view a close up of how the stitch should lie in the fabric, I'm curious to see the "inverted U" accurately- it's difficult to see the detail when I pause the video clips?
Thanks,
Cynthia
