Thanks, that's what I thought after I slipped them purl-wise and got those holes. And, yes, I think they do mark the edge of the sole. I think this is confusing when they don't tell which way to slip, because, as you guessed, I just don't know. I felt like after I slipped them purl-wise, that maybe that was not right, since I've been been doing the knit stitch before I join them in the round. If this comes up again, how will I know which way to slip if they don't state how--do you just go by what stitch you've been doing?
