PurplePidjin: No, what I did was, I put the hook through, yarn over, pulled through, y.o. again (so far so good) but then I only pulled through only one of the stitches. Then y.o. again and pulled through the second stitch to finish.
Obviously I should have pulled through both stitches instead of one then y.o. then the other seperately, but because I had been trippling for the rippling(!) for so long, I had that "wrap over twice" sensation before I realised what I was doing. The effect was fine, just like a snug dc really, but as soon as I started the real dc on row 2 I could feel straightaway it was a slacker stitch than the one I had, ahem, made up.
Ah well, live and learn... that's an hour of my life I won't get back but it's all a learning experience hey!
