How to Crochet the Long Wave Stitch | Step-by-Step Crochet Stitch Tutorial

If you’ve been crocheting for a while and you’re ready to try something that looks far more impressive than the effort it actually requires, the long wave stitch might be exactly what you’ve been searching for. With its sweeping, undulating texture and beautifully rhythmic pattern, this stitch creates fabric that mimics the gentle roll of ocean waves. It’s one of those stitches that makes people stop and ask, “How did you do that?” — and you’ll love being able to tell them it’s actually not that hard.

In this tutorial, we’re going to walk through everything you need to know to master the long wave stitch from scratch. Whether you’re a confident beginner who has mastered basic stitches or an intermediate crocheter looking to add something new to your repertoire, this guide will take you through materials, setup, the stitch pattern itself, and plenty of tips to help you succeed. Let’s dive in.

What Is the Long Wave Stitch?

The long wave stitch is a textured crochet stitch that creates a series of flowing, elongated curves across your fabric. It belongs to the family of ripple and wave stitches, which have been beloved in crochet for generations — think of classic Afghan blankets or the gorgeous textured throws you’ve admired in craft stores. What sets the long wave stitch apart from a standard ripple stitch is the length and smoothness of its undulation. Rather than sharp peaks and valleys, you get softer, more sweeping curves that give finished projects a modern, almost sculptural quality.

The stitch achieves this effect through a combination of increases and decreases worked at regular intervals, combined with stitches of varying heights. This creates the rise and fall that defines the wave pattern. Once you understand the logic behind how the waves form, the whole thing clicks into place and becomes wonderfully intuitive to work.

The long wave stitch is most commonly used for blankets, scarves, shawls, and baby afghans, but creative crocheters use it for everything from table runners to wall hangings. It works beautifully in a single color, but it truly comes alive when you use multiple colors to highlight each wave.

What You’ll Need

Before we get into the actual stitching, let’s make sure you have everything on hand.

Yarn: The long wave stitch works with almost any weight of yarn, but medium weight (also known as worsted weight or size 4) is the most forgiving for learning. It’s thick enough to see your stitches clearly without being too bulky to manage comfortably. If you want a lighter, drapier fabric — perfect for a shawl or scarf — try a DK weight (size 3) yarn. For a cozy, chunky blanket, a bulky weight can be stunning. Choose smooth yarn over textured yarn when you’re learning so you can easily see your stitch structure.

Crochet Hook: A size 5 mm (H/8) or 5.5 mm (I/9) hook pairs well with worsted weight yarn. Always check the yarn label for the manufacturer’s recommendation, though your tension may mean you need to go up or down a hook size to achieve the fabric you want.

Scissors and a Yarn Needle: You’ll need scissors to cut your yarn and a blunt-tipped yarn needle for weaving in ends when you finish.

Stitch Markers (optional but helpful): When you’re learning the pattern, stitch markers can help you keep track of your increase and decrease points until the rhythm becomes second nature.

Understanding the Stitches Involved

The long wave stitch uses just a handful of basic crochet techniques, so let’s make sure we’re on the same page before we begin.

Chain (ch): The foundation of most crochet projects. You’ll use chains to set up your starting row.

Single Crochet (sc): The shortest and simplest of crochet stitches. Insert hook, yarn over, pull up a loop, yarn over again, pull through both loops.

Half Double Crochet (hdc): One step taller than a single crochet. Yarn over, insert hook, pull up a loop (three loops on hook), yarn over, pull through all three loops.

Double Crochet (dc): The workhorse of crochet. Yarn over, insert hook, pull up a loop, yarn over and pull through two loops, yarn over and pull through the remaining two loops.

Treble (or Triple) Crochet (tr): A tall stitch. Yarn over twice before inserting the hook, then work off loops two at a time until one remains.

The long wave stitch uses these stitches in sequence — moving from the shortest to the tallest and back again — to create each wave’s rise and fall. It’s elegantly logical once you see it in action.

Setting Up Your Foundation Chain

The long wave stitch requires a foundation chain in a specific multiple. The most common version uses a multiple of 14 stitches, plus any additional chains for turning and setup. For a practice swatch, chain 30 (which gives you two complete wave repeats) and add 3 extra chains. So your starting chain would be 33 chains total.

If you’re making a full blanket or a wider project, simply multiply 14 by however many wave repeats you want and add your turning chains. For example, a blanket with 6 wave repeats would begin with a foundation chain of (14 × 6) + 3 = 87 chains.

Pro tip: Count your foundation chain carefully before you begin your first row. Losing track here means your waves won’t line up properly, and it’s much easier to fix at the start than several rows in.

Step-by-Step: How to Work the Long Wave Stitch

Now let’s get into the heart of this tutorial. We’ll work through the stitch row by row so you can follow along at your own pace.

Foundation Chain

Chain 33 (for a two-repeat practice swatch). If you’re following along with a different number of repeats, remember: multiples of 14, plus 3 chains.

Row 1

Turn your work and begin in the 4th chain from the hook (the skipped chains count as your first double crochet).

Work the following sequence across the row, repeating the bracketed section for each wave repeat:

Work 1 dc in the 4th chain from hook. Then work 1 dc in each of the next 5 chains (6 dc total so far in this wave). Now work 3 dc in the next chain — this is your increase point, and it’s what starts to push the wave upward. Work 1 dc in each of the next 6 chains. Then skip 2 chains and work 1 dc in each of the next 6 chains. Work 3 dc in the next chain (another increase). Work 1 dc in each of the next 6 chains.

If you have more wave repeats, continue the same sequence. At the end of the row, chain 3 and turn.

Don’t worry if this feels a little awkward at first. Every time you complete a full repeat, you’re building one complete wave, and the pattern will start to become visible by the end of your first row.

Row 2

Row 2 uses single crochet stitches and is what smooths out the bottom of the wave, creating the trough between peaks.

Chain 1 and turn. Work 1 sc in each stitch across the entire row. When you reach the 3-stitch increase point from the previous row, work 1 sc in each of those 3 stitches (you are NOT increasing here — just working one stitch into each). When you reach the 2-stitch skip from the previous row, work 2 sc together (sc2tog) to maintain your stitch count.

Chain 1 and turn.

Row 3

Row 3 begins to build height again using taller stitches. This is where the wave really starts to take shape visually.

Work across the row as follows for each wave repeat: Work 1 sc in the first stitch, 1 hdc in the next stitch, 1 dc in the next, 1 tr in the next 2 stitches, 1 dc in the next, 1 hdc in the next, 1 sc in the next. This creates your upward slope. Now work the trough: skip 1 stitch, then work the same ascending sequence in reverse: 1 sc, 1 hdc, 1 dc, 1 tr in the next 2 stitches, 1 dc, 1 hdc, 1 sc.

Repeat this sequence for each wave repeat across the row. Chain 1 and turn.

Row 4

Row 4 is a simple single crochet row worked across all stitches to set up the next wave sequence. Chain 1, turn, and work 1 sc in each stitch across. Chain 3 and turn.

Repeat

The long wave stitch pattern repeats from Row 1 through Row 4. Continue working these four rows until your piece reaches the desired length, ending after a Row 4 or a Row 2 for the cleanest finish.

Reading the Pattern at a Glance

Once you’ve worked a few repeats, you’ll start to see the pattern emerge and your hands will fall into the rhythm naturally. Here’s a quick summary of the four-row structure:

Row 1 is your foundation wave row, working double crochets with increases and decreases to set the wave structure. Row 2 is a single crochet smoothing row that locks in the shape. Row 3 is your statement wave row, building the stitch height sequence (sc, hdc, dc, tr, dc, hdc, sc) to create the dramatic wave crest. Row 4 is another single crochet row to reset for the next round of waves.

That four-row rhythm is the whole stitch. Elegant, isn’t it?

Tips for Getting Beautiful Results

Even straightforward stitches have their little quirks, so here are some tips to help your long wave stitch fabric come out looking polished.

Maintain consistent tension. Wave and ripple stitches can be prone to distortion if your tension changes significantly between stitches or rows. Try to keep your yarn flowing at a steady pace. If your fabric is curling or puckering along the wave edges, your tension may be too tight — try going up a hook size.

Count frequently in the early rows. Until the pattern is firmly in your muscle memory, count your stitches at the end of each row. A missed increase or decrease will throw off the entire wave alignment, and it’s far easier to catch errors early.

Use locking stitch markers at your increase and decrease points. Mark the center stitch of each 3-stitch increase group and the skip point of each decrease. Remove and replace them as you pass each one. This simple habit can save you significant frustration.

Block your finished piece. The long wave stitch responds beautifully to blocking — the process of wetting or steaming your finished project and pinning it flat to dry. Blocking opens up the stitches, evens out the waves, and gives the fabric a much more professional finish. This is especially true for natural fibers like cotton or wool.

Use color changes at the start of a new Row 1 for maximum visual impact. If you want to introduce a new color, do so at the very beginning of a Row 1. Cut your old yarn, join the new color, and continue. When you use a new color for every four-row repeat, the waves appear to cascade in ribbons of color — one of the most stunning effects in all of crochet.

Troubleshooting Common Issues

My waves aren’t lining up. This almost always comes down to a stitch count error in your foundation chain or an inconsistency in your increases and decreases. Lay your work flat and look at where the wave peaks and troughs fall. If they’re offset, count back to find where the error occurred.

My fabric is pulling in at the sides. This is a tension issue, most commonly caused by working the turning chains too tightly. Try working your turning chains a little more loosely, or consider adding a chain at the start of your turning chain sequence.

The waves look flat and not very pronounced. Make sure your stitch height variation is correct in Row 3. The sequence from sc up to tr and back down is what creates the dramatic crest. If you’re accidentally working all stitches at the same height, the wave effect will be lost.

I keep losing my place in the pattern. Try using a sticky note or a row counter app on your phone to track which row you’re on. Many crocheters also find it helpful to read Row 3 aloud as they work until the sequence is memorized: “short, medium, tall, tallest, tallest, tall, medium, short — skip — short, medium, tall, tallest, tallest, tall, medium, short.”

Project Ideas Using the Long Wave Stitch

Now that you know the stitch, let’s talk about what you can make with it.

Baby Afghan: A baby blanket worked in soft pastel yarns using the long wave stitch is an absolutely gorgeous gift. The soft undulation of the waves is soothing and beautiful, and the texture is gentle against delicate skin. Choose a soft acrylic or bamboo blend for easy care.

Lap Blanket or Throw: This is probably the most popular application for wave stitches. A full-size throw worked in three or four coordinating colors with color changes every four rows is one of those heirloom pieces that gets passed down through families.

Infinity Scarf: Work a long strip of the long wave stitch and seam the ends together for a dramatic, textured infinity scarf. A gradient yarn works particularly beautifully here, letting the color shifts emphasize the waves.

Table Runner: Worked in cotton yarn in natural or muted tones, a long wave stitch table runner adds artisanal charm to any dining space. The flat fabric lies beautifully on a table, and cotton is easy to launder.

Wall Hanging: Mount a finished long wave stitch panel on a dowel rod for a bohemian fiber art wall hanging. This works especially well with natural fiber yarns in earthy, undyed tones.

Yarn Color Suggestions

If you’re planning to use multiple colors, here are a few combinations that work particularly well with the long wave stitch.

Ocean-inspired blues and greens — think navy, teal, seafoam, and white — create an obvious but undeniably beautiful wave effect. Sunset tones in coral, gold, burnt orange, and cream feel warm and modern. For a more sophisticated palette, try a neutral gradient: white, ivory, oatmeal, taupe, and warm grey. For something bold and playful, look at jewel tones in emerald, sapphire, amethyst, and ruby.

If choosing multiple colors feels overwhelming, a self-striping or gradient yarn does all the color work for you. Simply work the stitch in a single self-striping skein and let the yarn create the waves of color on its own.

A Note on Gauge and Sizing

Because the long wave stitch is a repeating pattern, sizing adjustments are straightforward — you simply add or subtract wave repeats. Each repeat is 14 stitches wide, so knowing your gauge in double crochet will tell you approximately how wide each repeat will be in your chosen yarn and hook combination.

Work a gauge swatch by chaining 20 and working several rows of double crochet. Measure how many stitches and rows fit into a 4-inch square. Use that number to estimate how many wave repeats you need to reach your desired width. This is especially important for blankets and throws where you want to hit a specific measurement.

Final Thoughts

The long wave stitch is one of those crochet techniques that rewards patience and practice generously. The first time you work through all four rows and see a clean, sweeping wave emerge from your hook, you’ll feel that particular satisfaction that only a beautifully executed crochet stitch can produce. The more you work it, the faster and more fluid it becomes, until you can cruise through rows while watching a movie or chatting with a friend.

Whether you’re making a gift for a newborn, treating yourself to a stunning throw for your sofa, or simply building your crochet skills with a satisfying practice swatch, the long wave stitch is a wonderful addition to your crafting toolkit. Take your time with the first repeat, trust the process, and enjoy the rhythm. Before long, those gentle, rolling waves will be flowing off your hook like second nature.

Happy crocheting!
