How to Knit: Purling into the Back Loop/Front Loop

Purling into the front loops is the normal procedure and is used unless otherwise specified. Purling through the back loop twists the stitch. 

Purling Into the Front Loop 

Insert the right needle into the front of the stitch from right to left as shown and continue to purl the stitch. 

Purling Into the Back Loop 

Insert the right needle into the back of the stitch from back to front and continue to purl the stitch.
