Purl 2 Together Through Back Loop – P2 Tog TBL
The act of purling 2 together is the same concept of just regular purling into the back loop. In patterns, this is known as P2 Tog TBL. TBL is short form for Through Back Loop.
Instead of just grabbing one stitch from the back side, you have to grab two stitches. This step is going to cause 2 stitches to become one stitch when you are done.
