Oh, thank you, thank you, thank you!
That makes perfect sense to me. The thing is, I have
knit socks before (only a couple of pair, many months apart), so I'm somewhat familiar with the concept. I'm not experienced and confident enough yet, though, to know when a pattern's instructions don't make sense. I just assume I
can't make sense of it.
I really appreciate your help, and am off to finish that slipper.
