Slip, Slip, Slip, Knit (sssk)

The sssk, or slip-slip-slip-knit, is a left-leaning double decrease. It takes three stitches and turns them into a single stitch that slants toward the left.

To work a sssk, slip the first stitch on the left-hand needle as if to knit, slip the second stitch on the left-hand needle as if to knit, and slip the third stitch on the left-hand needle as if to knit. Slide the left-hand needle into these three stitches from left to right and knit them together through the back loops.

The following video demonstrates how to work a sssk. English style is shown first; Continental is shown at 1:58.
