A Slip Slip Purl Pass (s2pp) creates a centered double decrease, which means that it decreases two stitches and that it leans neither right nor left but, rather, stands straight up and down. It’s a wonderful detail, with its neatly pronounced ridge of knit stitches on right side of the fabric.

You work this decrease on the purl side, and essentially what you do is reorient the first two stitches then slip them purlwise through the back loop, purl 1, then pass the slipped stitches over. Let’s take a look!

 If you want to put this double decrease to use, you’ll find it in adding lovely detail to our Camber Pullover Pattern (NOTE: This pattern is no longer available). Give it a try!
