When you are working purl stitches and want to decrease one stitch then the p2tog or purl two stitches together is the ideal way of decreasing.
All you have to do is purl two stitches at the same time.
There are many different ways to decrease stitches in your work and they are referred to as 'decreases'.
When decreasing a stitch the way you do it will create a slope in the stitch to either the right or left and you should pick the type of decreases you use to create the end effect you want.
K2tog
Knit 2 stitches together. This creates a right leaning stitch.
SSK
Slip, slip and knit. Slip 2 stitches, one at a time, as if to knit, then knit those 2 stitches together through the back loops. This creates a left leaning stitch.
SSP
Slip, slip and purl. Slip 2 stitches, one at a time, as if to knit, then purl those 2 stitches together through the back loops. This is a trickier decrease to work as working 2 purl stitches together through the back loop requires a sharp needle tip.
