Centered Double Decreace Tutorial

My next tutorial is about centered double decrease (or s2kp2) which I like for the nicely thin and centered line it forms.  So let's start our lesson :)

For the decrease mark the center stitch (for example by using locking marker), knit one stitch before marked stitch.

Slip two stitches knitwise at the same time.

Knit the naxt stitch, which was after the marked stitch.

Now is the most tricky part, you may use a crochet hook in that step also.  Pass the two slipped stitches over the knitted stitch and off the needles.  

Not so difficult  and so pretty, right?
