The pattern is written for one size, but you will also find notes on how to adjust the dimensions to suit your preferences.
What Is the Herringbone Stitch?
Before diving into the pattern, it helps to understand what makes the herringbone stitch so special. Named after the skeletal structure of a herring fish, the herringbone pattern is a classic motif that has appeared in textiles, architecture, and design for centuries. In knitting, it creates a dense, interlocked fabric where stitches appear to zigzag across the surface in alternating diagonal lines.
The knitted herringbone stitch works by slipping and working stitches in a particular sequence that causes each stitch to lean over its neighbor, creating that distinctive woven appearance. The result is a fabric that is slightly thicker and more structured than ordinary stockinette, making it ideal for accessories like cowls, scarves, and hats where you want warmth and visual interest in equal measure.
One of the most appealing qualities of herringbone fabric is how differently it can look depending on your yarn choice. A smooth wool in a solid color will show off the texture with maximum clarity, while a variegated or heathered yarn will add a painterly, almost tweed-like quality to the finished piece.
Why a Cowl?
Cowls have earned their permanent place in the knitting world for good reason. Unlike scarves, they stay put. Unlike hats, they do not require careful shaping around a crown. A cowl is essentially a loop of fabric that sits around your neck and shoulders, providing warmth exactly where you need it without the fuss of tying or tucking.
A big, oversized cowl in particular is one of the most luxurious accessories you can knit. You can wear it doubled up close to the neck for a snug, layered look, or let it drape loosely over one shoulder for an effortlessly stylish silhouette. The Big Herringbone Cowl is designed to be generous in both circumference and height, so it functions beautifully in either position.
Materials
To make this cowl, you will need the following:
Yarn: Approximately 300–350 yards of a bulky weight yarn (US weight 5 or 6). A single-ply or loosely plied wool works beautifully for this pattern because the herringbone stitch benefits from a yarn with a little grip. Superwash wools, alpaca blends, and merino wool are all excellent choices. Avoid very slippery yarns like bamboo or silk blends for your first attempt, as they can make the slipped stitches harder to manage.
Needles: US size 10 (6mm) circular needles, 24 or 32 inches in length. The circular needle length matters because you will be working in the round, and you need enough length to comfortably hold all the stitches without them bunching.
Notions: A stitch marker to mark the beginning of the round, a tapestry needle for weaving in ends, and scissors. A row counter (physical or app-based) is optional but helpful.
Gauge
Gauge for this pattern is approximately 14 stitches and 20 rows over 4 inches (10 cm) in herringbone stitch. Gauge in herringbone stitch can be a little tricky to measure because the fabric is dense and has a slight horizontal compression compared to stockinette. Before casting on, knit a swatch of at least 20 stitches and 24 rows, wash and block it the way you plan to treat the finished cowl, and then measure.
If your gauge is looser than specified, go down a needle size. If it is tighter, go up a needle size. Gauge matters more for wearables than decorative items, but since a cowl needs to fit comfortably over your head to put on and take off, it is worth taking the time to get it right.
Finished Measurements
The finished cowl measures approximately 48 inches in circumference and 12 inches in height before any blocking. After wet blocking, the fabric will open up slightly and the height may increase to around 13–14 inches depending on your yarn. The large circumference allows the cowl to be worn doubled for a cozy, chunky look or single for a more relaxed drape.

Pattern Notes
This cowl is worked in the round from the bottom up. The herringbone stitch pattern is worked on right side rounds only, with purl rounds worked on wrong side rounds to create a smooth, reversible edge. However, since you are working in the round, every round is the right side — there is no wrong side facing you. The purl rounds in this pattern serve as rest rounds that help maintain the structure of the herringbone texture.
The herringbone stitch creates a fabric that is slightly narrower than the same number of stitches in stockinette. This is normal and accounted for in the stitch count.
When slipping stitches in the herringbone pattern, always slip them purlwise unless the pattern specifies otherwise. Slipping knitwise will twist the stitches and disrupt the herringbone effect.
It is strongly recommended that you work a small swatch in the round (or work flat and seam it) before starting the cowl, as the herringbone stitch has a learning curve for the first few pattern repeats. Most knitters find that after about two full repeats of the stitch pattern, it becomes intuitive and quite enjoyable.
The Herringbone Stitch Pattern (In the Round)
The herringbone stitch for working in the round is worked over any even number of stitches. Here are the two rounds that make up the pattern:
Round 1 (Herringbone Knit Round):
Insert the right needle into the second stitch on the left needle and knit it, then knit the first stitch and slip both stitches off the left needle together. Repeat this sequence to the end of the round.
Round 2 (Herringbone Purl Round):
Insert the right needle into the second stitch on the left needle and purl it, then purl the first stitch and slip both stitches off the left needle together. Repeat this sequence to the end of the round.
These two rounds form the complete herringbone stitch pattern. You will repeat them throughout the body of the cowl.
Pattern Instructions
Cast On
Using your preferred long-tail or cable cast-on method, cast on 168 stitches. Join to work in the round, being careful not to twist your stitches. Place a stitch marker to indicate the beginning of the round.
The long-tail cast on is recommended for this pattern because it creates a flexible, slightly stretchy edge that complements the herringbone fabric.
Ribbed Border
Work a simple 2×2 ribbing for the bottom border to give the cowl a neat, stable edge that will not curl.
Rounds 1–8: K2, p2; repeat from to end of round.
After 8 rounds of ribbing, you will have a neat, stretchy cuff at the base of the cowl.
Body
Now you will transition into the herringbone stitch pattern. Work as follows:
Round 1 (Herringbone Knit Round): Knit into the second stitch on the left needle, then knit the first stitch, slip both off together; repeat from to end of round.
Round 2 (Herringbone Purl Round): Purl into the second stitch on the left needle, then purl the first stitch, slip both off together; repeat from to end of round.
Repeat Rounds 1 and 2 until the body of the cowl measures approximately 11 inches from the cast-on edge, or until you have approximately enough yarn left to work 8 rounds of ribbing plus bind off.
The body of the cowl for a standard version will take approximately 50–60 rounds total of the herringbone pattern, depending on your gauge.
Top Ribbed Border
Repeat the ribbing sequence used for the bottom border.
Rounds 1–8: K2, p2; repeat from to end of round.
Bind Off
Bind off all stitches in pattern, working k2, p2 as you bind off to maintain the elasticity of the ribbing. Do not bind off too tightly — a loose, stretchy bind off is essential for a cowl that will slip comfortably over your head.
If you struggle with tight bind offs, try using a needle one or two sizes larger for the bind off row only.
Finishing
Cut the yarn, leaving a tail of approximately 8 inches. Thread the tail onto a tapestry needle and weave it in securely on the wrong side of the fabric, working the tail through several stitches in different directions to anchor it well. Repeat with the cast-on tail.
Blocking
Blocking this cowl is highly recommended and makes a noticeable difference in the final appearance of the herringbone stitch. The texture will open up, even out, and the fabric will soften considerably.
To wet block the cowl, fill a basin with cool to lukewarm water and add a small amount of wool wash or gentle soap. Submerge the cowl and gently press it into the water until fully saturated — do not agitate or wring it. Let it soak for 15–20 minutes.
Lift the cowl out of the water carefully, supporting its full weight to avoid stretching. Gently press (do not wring) the water out, then roll the cowl in a clean towel and press firmly to remove excess moisture.
Lay the cowl flat on a blocking mat or clean, dry surface. Shape it to your desired dimensions, patting and easing the fabric gently. Allow it to dry completely before wearing, which may take 24 hours or more depending on your environment.
Yarn Substitution Tips
The pattern above is written for a bulky weight yarn, but the herringbone stitch works beautifully in a range of yarn weights. If you want to make a lighter, more drapey version, consider dropping down to a worsted weight yarn (US weight 4) and adjusting your needle size accordingly. You will need a higher stitch count to achieve the same circumference, so increase your cast-on by working a swatch first and calculating the stitches needed.
For an ultra-cozy, extra-chunky version, a super bulky yarn (US weight 6) will knit up very quickly and create a dramatically thick, puffy fabric. Reduce your stitch count and needle size accordingly, and be prepared for the herringbone stitch to be a bit more of a hand workout with such thick yarn.
Whatever yarn you choose, look for something with good stitch definition. The herringbone pattern relies on being able to see the interlocking structure of the stitches, so yarns with a clear, smooth twist will showcase the pattern best.
Customization Ideas
One of the joys of making your own knitwear is the ability to tailor it to your exact taste. Here are a few ways to make this Big Herringbone Cowl uniquely yours.
Change the width: To make a narrower cowl that wears more like a traditional neckwarmer, cast on 120 stitches instead of 168. For an even more dramatic, oversized infinity-scarf style cowl, cast on 200 or more stitches.
Change the height: For a shorter, snugger cowl, reduce the number of herringbone body rounds. For a longer cowl that can be folded into multiple layers or worn as a hood, increase the body rounds until the piece measures 18 or even 20 inches.
Add a stripe: Work the ribbing in a contrasting color and switch to your main color for the body. This simple detail adds a polished, intentional look with very little extra effort.
Try a seed stitch border instead of ribbing: For a flatter, more textured edge, replace the k2, p2 ribbing with seed stitch (k1, p1 alternating, with stitches offset on each round). This creates a border that lies flat and complements the organic texture of the herringbone.
Troubleshooting Common Issues
The herringbone is too tight and difficult to work: This is a common issue when you are first learning the stitch. Make sure you are not holding your yarn too tightly, and try going up a needle size for more ease. Loosening your tension as you work the slip stitches will help significantly.
My stitch count keeps changing: If you find yourself gaining or losing stitches, count carefully at the end of each round. The most common cause of stitch count errors in herringbone is accidentally knitting or purling into the same stitch twice rather than working one stitch and slipping the other. Slow down and be deliberate until the stitch pattern becomes automatic.
The fabric looks twisted or uneven: This usually happens when stitches are slipped knitwise rather than purlwise. Double-check that you are always slipping with the right needle inserted from right to left (purlwise) unless the pattern specifies otherwise.
My seam line is visible: Because you are working in the round, you may notice a slight jog where the beginning of the round meets the end. This is normal and usually becomes less visible after blocking. Placing your beginning-of-round marker in a less prominent spot (along a side rather than at the front center) can help minimize its appearance.
