KnittingThrough back loop
Description
Indicates that the stitch should be worked through the back leg of the loop rather than the front, typically to twist the stitch.
Detailed explanation
This abbreviation directs you to insert the needle into the back leg of the stitch on the holding needle, instead of the standard front leg. Working through the back loop twists the stitch at its base, creating tighter tension and a more defined vertical line. It is frequently used in ribbing patterns to produce a sharper look or when working increases to prevent holes.
