How to Sl1, K1, psso – left leaning decrease

Wondering how to Sl1, K1, psso? You’ll find this technique used in many knitting patterns to decrease one stitch. Follow these three simple steps or watch the short 1-minute video tutorial to see how each stitch is worked.

S1, K1, psso Tutorial

    1. Slip one stitch, knit wise, to right-hand needle.
    2. Knit the next stitch.
    3. Using the left-hand needle. Pass the slipped stitch over the knitted stitch.

1 stitch has been decreased. Note how it leans to the left.

If you’re a visual learner watch this short video which clearly shows how to decrease a stitch using Sl1, K1, psso. We’ve used The Fibre Co. Tundra yarn and a pair of metal needles.
