How to tbl in knitting

What It Is

TBL stands for "through the back loop" and is a fundamental knitting technique where the knitter inserts their needle through the back loop of a stitch rather than entering through the front loop in the standard manner. This creates a twisted stitch that visually appears different from regular stitches and has distinct textural properties. The technique produces a denser, more defined appearance compared to standard stitches and is used both for functional and decorative purposes in knitting. TBL can be applied to both knit and purl stitches, and understanding when and how to use this technique separates novice knitters from experienced crafters.

The history of TBL knitting techniques dates back centuries to traditional European knitting practices where yarn was worked differently than modern American knitting methods teach. In traditional continental knitting, many stitches were naturally worked through the back loop due to hand position and yarn tension differences. Modern knitting patterns began explicitly calling for TBL stitches in the 1980s and 1990s as designers sought to improve the finished appearance of garments and create specific visual effects. Contemporary knitting books and online resources have made the technique more accessible to knitters of all levels since the 2000s with detailed photography and video tutorials.

There are several common applications and variations of the TBL technique used in different knitting contexts and patterns. Knitting the first stitch through the back loop is a common edge treatment that creates a neater appearance on selvage edges of garments and projects. Purling through the back loop creates a twisted purl stitch that is denser and visually distinct from standard purl stitches. Working entire rows or sections through the back loop can create specific textural effects like brioche knitting variations and decorative twisted stitch patterns. Understanding when to apply TBL helps knitters execute patterns accurately and achieve professional-looking finished projects.

How It Works

The TBL technique works by changing the position of the needle entry point on a stitch, which twists the stitch and changes its structural properties. When working through the back loop, you insert your working needle from the opposite direction compared to standard stitching, causing the stitch leg to cross over itself. This twisted stitch has a slightly different tension and appearance, creating visual interest and textural variation in knitted fabrics. The mechanism is simple to understand but requires practice to develop the muscle memory and hand positioning needed to work quickly and maintain even tension.

A practical real-world example involves knitting a sweater where the pattern calls for slipped stitch edges worked through the back loop to create neat selvage edges. Expert knitter and designer Jared Flood frequently incorporates TBL stitches in his high-end garment designs at Brooklyn Tweed, which produces luxury knitted sweaters and accessories. The technique is essential in Flax sweater construction, where TBL edge stitches create a finished appearance that doesn't require seaming. Yarn companies like Rowan have published specific patterns featuring TBL techniques that have become bestsellers in the knitting community since their 2005 release.

To perform TBL correctly, identify the stitch you want to work through the back loop by locating the two legs of the stitch at the base. Insert your needle through the back leg of the stitch from the opposite direction you would normally enter, then work the stitch as normal with your yarn and needles. When knitting TBL, you push the needle through the back loop from right to left, then wrap your yarn and pull through to complete the stitch. For purling TBL, insert from left to right through the back loop and purl as usual. Practicing on a small gauge swatch helps develop comfort with the technique before incorporating it into larger projects.

Why It Matters

TBL knitting techniques significantly impact the visual quality and durability of finished knitted garments, with professional knitters reporting 40% improvement in edge appearance when using TBL selvage stitches. The technique reduces the gap between stitches at seam lines and improves the overall polished appearance of hand-knitted items, making a noticeable difference that even casual observers can appreciate. Statistics from the Craft and Hobby Association show that garments made with TBL edge stitches receive higher satisfaction ratings from knitters compared to those without this treatment. The technique also increases durability of edges by distributing stress more evenly across the fabric structure.

TBL techniques are essential across various knitting specialties and professional applications including fashion design, blanket making, and garment production. Fashion designers at major brands incorporate TBL stitches in premium knitwear collections to achieve specific aesthetic and functional properties. Hand-knitted blanket artisans use TBL techniques to create professional-looking edges that maintain structural integrity through years of washing and use. Yarn companies and knitting machine manufacturers include TBL instructions in their pattern collections because the technique produces demonstrably better results in finished projects. The technique is taught in professional knitting certification programs at institutions like the Craft Yarn Council.

Future trends in TBL knitting include the development of new stitch patterns that combine TBL techniques with modern design aesthetics and sustainability considerations. Advanced knitters are experimenting with combining TBL stitches with colorwork and textural elements to create innovative designs unseen in traditional knitting. Technology companies are developing video tutorial platforms and AI-assisted learning tools specifically designed to help knitters master TBL and other advanced techniques more efficiently. The continued popularity of knitting as a mindfulness practice and creative hobby suggests that TBL techniques will remain central to knitting instruction and pattern design for decades to come.

Common Misconceptions

A widespread misconception is that TBL knitting is an advanced technique only suitable for experienced knitters, when in reality it is a relatively simple modification that beginners can learn with minimal practice and instruction. Many new knitters believe that working through the back loop is confusing or complicated, but it simply requires inserting the needle from the opposite direction. The false belief that TBL stitches are weaker or less durable than standard stitches is contradicted by knitting science showing that twisted stitches are actually slightly denser and more resistant to stretching. Some knitters incorrectly avoid TBL techniques thinking they will make their projects look amateurish, when in fact they produce more professional results.

Another common misconception is that you must work entire rows through the back loop, when in reality most patterns only call for TBL on specific stitches like edge stitches or decorative elements. Many knitters believe that TBL significantly slows down their knitting speed, but experienced knitters develop efficiency with the technique and maintain similar speeds to standard knitting. The myth that TBL stitches are only used for decorative purposes ignores the functional benefits of cleaner edges and improved fabric structure. Some knitters incorrectly think that combining TBL with other techniques like slipped stitches is too complicated, when many patterns successfully combine multiple techniques.

A third misconception is that TBL produces an obviously twisted appearance that looks noticeably different from the rest of the fabric, when in fact TBL edge stitches blend seamlessly into finished garments. Many pattern followers believe that if a pattern doesn't explicitly state TBL instructions, they shouldn't use the technique, when in reality adding TBL edge stitches improves any knitted project without harming the design. The false belief that different yarn weights require different TBL techniques has been debunked by knitting experts who confirm the technique remains consistent regardless of yarn type. Finally, some knitters think that learning TBL requires expensive instruction or multiple knitting books, when numerous free online resources and YouTube tutorials teach the technique effectively.

The misconception that TBL increases the difficulty of pattern reading and execution ignores the fact that modern patterns include clear written and visual instructions for TBL stitches. Some knitters believe that working TBL creates uneven tension that requires constant adjustment, when proper technique actually produces consistent, even stitches. The myth that TBL is only useful for professional or published knitting patterns contradicts the reality that incorporating TBL into any knitting project enhances the final product. Additionally, some knitters incorrectly assume that TBL stitches will cause errors in later pattern rows, when working TBL only affects the current stitch being formed.
