Reverse Left-Leaning Bar Increase

When working a kfb, on the knit side of your fabric, you work to the stitch you want to increase. Usually, this is the stitch after a stitch marker. Then you knit into the front leg and the back leg of the same stitch before slipping it off the non-working needle. The result is an extra stitch on the next to the original one that has a little bar across its base, like the below image.

To create this exact look from the other side of the fabric, on the purl side:

1. Work to one stitch before marker. Slip stitch knitwise onto working needle, then slip directly (purlwise) back onto non-working needle.
2. Knit into the front leg. Drop stitch from non-working needle.
3. Working into the stitch directly below the one you just created on the working needle, use the non-working needle to pick up the loop closest to your dominant hand from the dominant-hand side of the yarn. This will create a loop on the non-working needle with the leg closest to the needle tip in front, extending from the same stitch you just worked into.
4. Purl into the front leg of this picked-up stitch.

That's it! If you check the knit side of your work, it should look like you just made a kfb—except you and I both know better, don't we? *wink, wink.*
