Update: I went to Ravelry to look something up and decided to make this first post there, and in writing up what I thought was an error in the instructions, I realized I may have made an error in my implementation.
In the Vogue instructions, the Row 4 repeat ends with
wyib sl next 2 sts;
drop sl st off needle to front of work;
sl same 2 sts back to LH needle;
pick up dropped st and k it;
It doesn’t say what to do with those two stitches that you slipped and then put back on the LH needle. I assumed that they should be knit. However, my implementation doesn’t look very much like the Vogue picture. The Vogue picture looks kinda like this, giving the impression of a solid ribbon that twists around, but mine looks more a solid ribbon that never twists but occasionally does have a loose stitch pulled diagonally across. So maybe knitting those two dropped stitches isn’t the right thing, but following the instructions you still end up with them on the LH needle, so what are you supposed to do?
