SIMPLE STEPS P2TOG
The purl two together stitch (p2tog) is used to combine two stitches on a purl row, decreasing one stitch each time you use it. From the purl side of the work it leans left, so when viewed from the right (knit) side in stocking stitch it will lean right, and look like you’ve made a k2tog stitch on the knit side of the work. 1 With your yarn held at the front of the work, insert your right-hand needle into the next two stitches purlwise, from right to left. 2 Wrap the yarn around the front of both stitches anti-clockwise, and push the new loop to the back. 3 Drop the two old stitches off the left-hand needle and you will be left with a single stitch on your right-hand needle. You’ve decreased one stitch.
