How to work it

Purl into the next stitch but leave it on the left needle. Bring the right needle behind the work, purl into the back loop of the same stitch, then slide it off. Your count goes up by one. It is used when an increase falls on a wrong-side row, or in reverse stockinette and garter where the little bar it leaves blends into the surrounding bumps.

Common confusions

What does pfb mean?

In knitting patterns, pfb means Purl front and back. The purl-side version of kfb, turning one stitch into two.

Is pfb just kfb done on the purl side?

Yes, in effect. It produces the same two-from-one increase with the same small bar, worked with purl motions instead of knit ones. If a pattern shapes on both right-side and wrong-side rows, kfb and pfb are the matching pair.

Why is the second half so hard to reach?

Purling into a back loop means angling the needle behind fabric that is already in front of your hands. Pushing the stitch closer to the tip of the left needle and giving it a little slack makes the back loop open up enough to enter cleanly.
