Purl 2 Together, Slip 1 Back, Pass Next Stitch Over, Slip 1 (p2sps)

The p2sps—or purl 2 together, slip 1 back, pass next stitch over, slip 1—is a left-leaning double decrease worked on the wrong (purl) side. It takes three stitches and turns them into one stitch. On the right side, it looks like a sk2p. It’s not a common stitch, so I made the abbreviation up.

To work it, purl the next two stitches on the left-hand needle together. Holding your working yarn in front (toward the wrong side), slip the stitch you just created back to the left-hand needle. Use the right-hand needle to lift the next stitch (the first unworked stitch) on the left-hand needle up and over the slipped decrease stitch and off the needle. Finally, slip the decreased stitch back onto the right-hand needle.

I was not able to find a video that demonstrates this stitch, and I am not able to make my own at this time. If the above isn’t working for you, you can work a slip, slip, slip, purl (sssp).
