Purl Through Back Loop – P TBL
Purling through the back look sounds more complicated than it is. This motion causes the stitch to turn around. Instead of diving straight in to purl, you have to move the needle to around the back and come at the loop from the opposite direction.
This method takes a bit of practice but isn’t hard to do. In patterns this is P TBL. TBL is short form for Through Back Loop.
