Sl1-k2tog-psso: How to work a slip 1, knit 2 together, pass slipped stitch over decrease

A sl1-k2tog-psso (slip 1, knit 2 together, pass slipped stitch over) is a double decrease, meaning it decreases 2 stitches from the total stitch count. It is a directional decrease and it leans left.

It is worked in 3 steps, as you might imagine from the abbreviation sl1 …. k2tog ….. psso. 

How to work sl1-k2tog-psso in 3 easy steps

1. Slip one stitch, knitwise, from the left hand to the right hand needle (for more information on slipping stitches, check out this post here)
2. Knit the next two stitches on the left hand needle together (here’s how to work a k2tog),
3. Using the left hand needle tip, lift the slipped stitch up and over the k2tog, and let it fall off the right hand needle tip.

Working a sl1-k2tog-psso decreases the stitch count by 2 stitches, because you have effectively gathered three stitches together into a single stitch.  If you work a series of sl1-k2tog-psso (every other row) stacked on top of each other, you create a left-slanting line.
