So you may wonder, why twist a purl stitch? You’ll often find this technique used when you have traveling stitches and you want to mirror those created on the row below.
For example, let’s say you want to work an ssk, (slip, slip, knit) which is a decrease worked on the knit-side and makes your new stitch slant to the left. On the next row, let’s say you need to decrease in that very same spot and you need your stitch to continue to slant to the left. In this case you would p2tog (purl two together) but through the back loops, which would also make this new stitch slant to the left. To learn how to work a Twisted Purl stitch, click here.
