I'm at work (so no yarn-in-hand), but let me see if I can wrap my brain around this...
In the picture I posted, to "slip" the loose bit I would just pop the loose bit over to the other needle but not "stitch" (wrap the source yarn around the tip of the other needle and pull it through/whatever) it?
Wouldn't that leave a gap or something undone looking since there'd be no stitch?
Of course, I'm sure it would make sense if I had yarn in my hands, so the answer to my comments may be "try it when you get home and it'll make sense."
And yes, I'm quite enjoying the knitting and I'm looking forward to having my first scarf made one of these years.
