Yeah, some pics will probably be helpful in learning SSK. It is definitely different than K2 tog. I will try to explain, never know
Slip both stitches knitwise (like you're gonna knit 'em) onto the right hand needle. Insert your left hand needle into both stitches from left to right. Grab the yarn and pull it through both stitches at once. It's kind of strange. You have to do it once and then you'll be all excited and you'll wanna do it more! It's almost mystical the way it happens. Try it and if it still ain't happenin, see if you can download a video.
