Another question:
I noticed in the video for k2tog ("combo style" supposedly) posted by the skinny lady in pjs (

) that the yarn goes OVER the back of the needle rather than under it and around the front as it normally does in combination knitting. Is that correct?
I don't understand how knit stitches are made (at all!), so I'm wondering why the heck combination knitting has to resort to "regular" knitting to get the desired decreases!!! Very frustrating--especially when combination knitting is SO much easier.
