Oh. I can't do them wrapped. The 2nd wrap always had either a gaping hole or a big square of yarn, y'know?
I just turn, purl to the other marker, turn knit until there's 1 stitch before the gap, slip that stitch purlwise, take the left needle, pick up the stitch directly underneath from the back. Put the slipped stitch back on the left needle, knit the slipped stitch normally, knit the next 2tog (picked up stitch and the one right after).
When you get around to 1 stitch before the 2nd gap (should be 1 after the marker if you use them), slip it onto the right needle KNITwise, use the right needle and pick up the stitch directly under the next stitch on the left from the back, put it on the left needle, move the slipped stitch back and knit the 2tog through the back, then keep knitting as normal.
The link I gave you to Ruth's instructions is a lot clearer, though.
