What? Yah, it may seem like I am speaking gibberish but I do know what I am trying to convey. KFB stands for Knit into the front and back of the stitch.
I was looking for some written instructions but I couldn't find them, however I did find a video that I made a few years ago. After finding the video, I had to make the written instructions to have on file.
I hope you find them useful. I tried to take step by step pictures but I don't know if they make sense, I think the video shows the steps a little better.
kfb/kf&b: knit into the front and back of the stitch. Also known as the bar increase. It is as it description says, you create a two stitches out of one by knitting into the front leg of the stitch and then knitting again onto the back leg of the stitch. Although in needle knitting is quite simple, for loom knitters this type of increase requires an empty peg where you want to create the increase, meaning we need to move loops around. Prior to creating the stitch, you will need to move the loops from the pegs to open a peg for the increase.
The main characteristic that this increase demonstrates is a small bar created by knitting into the back of the leg. You can see it in the picture above (it is pointed by the tip of the knitting tool)
To demonstrate: the increase is being created from a Right to Left direction on the knitting loom, in our example, the increase will take place at peg 3.
Step 1: Knit peg 1 and move the loop to the empty peg to the right (peg 1 is now empty).
Step 2: Knit peg 2 and move the loop to empty peg 1 (peg 2 is now empty).
Step 3: Holding the loop on peg 3, knit peg 3 (do not let the original loop pop off the peg). Place the newly formed loop on peg 2. Peg 3 remains with the original loop on it.
Step 4: E-wrap peg 3 and lift the bottom loop up and off the peg.
Steps 1-4 created a kfb at peg 3. Continue working the other pegs as the pattern directs.
