A step by step tutorial for the KLL knitting increase. By knitting through the left loop, you get a very invisible right-leaning increase.
A lot of increases are very visible. When you are knitting a lace shawl, then this is actually what you are looking for as those beautiful eyelets are created that way. But for stockinette stitch and similar patterns, make one right or yarnover is not what you want. By knitting through the left loop of the stitch two rows below, you get an increase that is almost invisible. Here’s how you do it.
ⓘ In knitting patterns, this stitch is usually abbreviated with “KLL”. This increase is sometimes also called LLI, left lifted increase. There is also a left-leaning counterpart called KRL or knit right loop.
Knitting KLL step by step
Note: I am using a contrasting red yarn for instructional purposes only.
This knitting increase works best in a knit row with another knit row below.
Step 1: Knit a stitch as normal as preparation (note: this stitch is technically speaking NOT part of the KLL, so if your pattern says KLL it means you have to perform the steps starting from #2)
Step 2: Insert your left needle into the stitch two rows below the one you just knitted on your right needle from the back so you don’t twist it (the red one in the picture above).
Step 3: Now, pick up only the left leg of that stitch and lift it on your left needle. Don’t pick up the whole stitch.
Step 4: Knit this extra loop through the back loop.
Step 5: Continue knitting according to your pattern.
And there is your KLL increase.
Note: I do believe KLL is one of the most inconspicuous increases there is. It only looks super neat, however, if there are at least 3 rows in between each increase. If you want to increase in every knit row making one through the back loop (M1R) is probably the better choice.
There is also a corresponding knit through the right loop, which would be left-leaning BUT it creates a visible little hole with most yarns. If you knit that one through the back loop, then there will be no hole, but the twist will be visible. That’s why I usually stick with KLL on both sides of a project.
