How To Knit Through Back Loop: Master The Twisted Stitch Technique
Knitting through the back loop (ktbl) is a fundamental manipulation technique that twists the stitch upon creation, reducing column width, increasing structural rigidity, and producing a distinct diagonal ribbing effect. Mastering this maneuver is essential for executing twisted stitch ribbing, stabilizing buttonbands, and correcting misoriented stitches mounted incorrectly on your knitting needles.
Pre-Procedure Planning for Twisted Stitches
Executing the knit through back loop technique successfully requires careful attention to stitch orientation, needle sizing, and yarn composition. Because a twisted stitch uses slightly more yarn and lacks the elasticity of a standard knit stitch, understanding your materials prevents puckered fabric and unintended tension distortion.
- Essential Gear & Tools: Straight or circular knitting needles matching your gauge requirements, a smooth-ply yarn (such as wool, alpaca, or acrylic blends), and locking stitch markers to track project progress.
- Mandatory Prerequisite Knowledge: Familiarity with the standard knit stitch, correct needle-holding ergonomics, and the ability to identify the leading versus the trailing leg of a stitch mounted on the needle.
- Benchmarks & Standards: Expect a firmer, less stretchy fabric column. Allocate approximately 15 to 20 minutes of dedicated practice swatching to achieve consistent tension across multiple rows of back-loop manipulation.
Step-by-Step Workflow for Knitting Through the Back Loop
Step 1: Identify Stitch Orientation and Leg Placement
Examine the next stitch waiting on your left-hand needle. On a standard Western stitch mount, the right leg of the V-shape sits on the front of the needle, while the left leg sits on the back of the needle. For a standard knit, you enter the front leg. For knitting through the back loop, your target is always the trailing leg—the one positioned behind the needle.
Pro-Tip: Always inspect your stitches after turning your work. If your previous row left stitches mounted in the reverse direction (eastern mount), the back leg will be the right leg instead of the left.
Step 2: Position the Right-Hand Needle Entry Angle
Hold your working yarn in your preferred style (continental or English). Take the tip of your right-hand needle and insert it from left to right directly into the back loop (the leg furthest away from you) of the first stitch on the left-hand needle.
Warning: Avoid splitting the plies of the yarn when inserting your needle. Ensure the needle tip passes cleanly under the back leg without piercing the fiber strands.
Step 3: Wrap and Draw the Working Yarn Through
With the right-hand needle inserted through the back loop from front to back behind the left needle, wrap the working yarn counterclockwise around the right needle tip just as you would for a standard knit stitch. Use your right index finger to guide the yarn snugly around the needle barrel.
Step 4: Complete the Stitch and Slide Off
Using the hook of the right needle, pull the newly formed loop through the back of the stitch. As you pull the new loop through, gently slide the old stitch off the tip of the left-hand needle. Ensure the newly created stitch rests on the right-hand needle with its right leg positioned at the front, completing the twist.

Technical Comparison of Standard Knit Versus Back Loop Stitch
| Parameter | Standard Knit (K) | Knit Through Back Loop (KTBL) |
|---|---|---|
| Stitch Orientation | Open, untwisted V-shape | Closed, twisted at the base |
| Fabric Elasticity | High horizontal and vertical stretch | Low stretch, highly stable |
| Gauge Impact | Standard row and stitch count | Narrower columns, tighter density |
| Primary Use Cases | Stockinette body, general shaping | Twisted ribbing, fixing mounted stitches |
Common Knitting Failures and Field Fixes
- Root Cause: Splitting the yarn ply during needle insertion. Actionable Fix: Use a needle size with a sharper point, and deliberately slow down your entry angle, ensuring the needle tip glides cleanly under the entire strand of the back leg.
- Root Cause: Overtightening the working yarn, making subsequent rows nearly impossible to work. Actionable Fix: Relax your grip on the working yarn and use the barrel of the right needle—not the tapered tip—to size the new loop.
- Root Cause: Accidentally twisting the stitch twice by working a backward-mounted stitch through the back loop. Actionable Fix: Check the stitch mount before insertion; if the leading leg is in the back, work it through the front loop to reset its orientation.
Frequently Asked Questions
What is the difference between a standard knit and a knit through back loop?
A standard knit stitch enters the front leg of the stitch, leaving the legs open and parallel. Knitting through the back loop enters the rear leg, which crosses the legs of the stitch at the base, creating a firm, twisted loop that alters both the texture and elasticity of the fabric.
Why does my ribbing look twisted when I use this technique?
Twisted ribbing is an intentional aesthetic choice achieved by working every knit stitch through the back loop. This draws the columns closer together, creating a crisp, sharply defined ribbed fabric with less flare than standard 1x1 or 2x2 ribbing.
Can I use ktbl to fix a twisted stitch on my needle?
Yes. If a stitch is mounted incorrectly with the trailing leg in the front, working it through the correct loop (the one positioned at the back) will align the legs properly and un-twist the stitch on the following row.
Does knitting through the back loop use more yarn?
Yes. Because the yarn must travel a slightly longer diagonal path around the needle to form the twist, projects worked entirely in ktbl consume roughly 5 to 10 percent more yarn than standard stockinette fabric.
