Yes, yes, that's happening to me! I cannot possible knit the stitch any tighter, yet the ladder is as bad, and sometimes worse, as when I don't even try. Grr! That's why I figured I must be missing something.
But, if a sock maven like yourself has this problem, at least I know I'm in good company
Oh, and I'm using your tutorial, Silver, for the grafting...it's not going so well--through no fault of yours, I might add--but I shall perservere because I really REALLY like knitting socks, ladders and all!
