With its rhythmic stitch pattern and graceful undulating rows, this blanket has become a favorite among crocheters of all skill levels who want something beautiful without an overwhelming level of complexity. Whether you are wrapping it around your shoulders on a cool evening, draping it over the back of a couch, or gifting it to someone you love, the Tonnta Wave Blanket delivers that perfect combination of handmade warmth and visual elegance.
In this post, I am sharing the complete free pattern for the Tonnta Crochet Wave Blanket, along with tips, material suggestions, step-by-step guidance, and a video tutorial to walk you through every stitch. If you have ever wanted to try a wave or ripple pattern but felt intimidated, this is the project to change your mind.
What Does “Tonnta” Mean?
The word “tonnta” comes from the Irish language, meaning “waves.” It felt like the perfect name for this blanket because every row genuinely mimics the rise and fall of ocean waves. There is a meditative quality to crocheting this stitch once you get the rhythm down — your hook rises and dips, the yarn flows, and before long you have created something that looks like it was made by someone with years more experience than you may have. That is part of the magic of wave crochet patterns.
Who Is This Pattern For?
The Tonnta Crochet Wave Blanket pattern is written for confident beginners and intermediate crocheters. If you can execute a chain, single crochet, half double crochet, double crochet, and slip stitch, you have everything you need to complete this project. The wave effect is achieved through simple increases and decreases at strategic points in each row, which creates that undulating silhouette. It takes a row or two to get the hang of it, but once you do, your hands will practically move on their own.
If you are a complete beginner, I would recommend practicing these basic stitches on a small swatch before jumping in, or simply follow along closely with the video tutorial linked later in this post.
Materials You Will Need
Before you begin, gather the following:
Yarn: Approximately 1,200–1,800 yards of worsted weight yarn (depending on your desired finished size). This pattern works beautifully in a single color, but it truly shines when you use multiple colors to highlight those waves. Acrylic yarn is budget-friendly and easy to wash, making it perfect for a blanket you plan to use every day. If you want something with a softer hand, consider a cotton-acrylic blend or a high-quality premium acrylic like Paintbox Simply DK or Lion Brand Pound of Love.
Hook: 5.00mm (US H/8) crochet hook for worsted weight yarn. If you are using DK weight, go down to a 4.50mm hook.
Notions: Scissors, yarn needle for weaving in ends, and stitch markers to help keep track of increases and decreases as you learn the pattern.
Gauge: 14 stitches and 8 rows = 4 inches in double crochet. Gauge is especially important for wave patterns because even a small difference in tension can affect how the waves look. Crochet a gauge swatch and adjust your hook size up or down if needed.
Finished Size
The pattern as written creates a blanket approximately 40 inches wide by 52 inches long — a generous lap blanket or a cozy throw. You can easily size it up or down by adjusting your starting chain. Instructions for resizing are included in the pattern notes below.
Pattern Notes
This pattern is written in US crochet terms. Here is a quick reference:
ch = chain
sl st = slip stitch
sc = single crochet
hdc = half double crochet
dc = double crochet
sk = skip
sp = space
rep = repeat
[ ] = repeat the instructions between brackets the number of times indicated
Foundation Chain: The Tonnta Wave Blanket uses a multiple of 14 + 3 for the foundation chain. For the standard throw size, chain 199. To go wider, add 14 stitches for each additional wave repeat. To make it narrower, subtract 14 stitches per wave.
Turning Chains: This pattern uses a turning chain of 3, which counts as the first double crochet of each row.
Color Changes: If you are working with multiple colors, change your yarn color at the end of a row, just before pulling through the final loop of your last stitch. This keeps the color change neat at the edge.
The Tonnta Crochet Wave Blanket Pattern — Step by Step
Setting Up Your Foundation
Begin by making a slip knot and chaining 199 (or your adjusted number based on the formula above).
Row 1 (Foundation Row): Starting in the 4th chain from your hook (this counts as dc + ch 1 skipped), work as follows across the chain: 1 dc in each of the next 5 chains, skip 2 chains, 1 dc in each of the next 5 chains, [1 dc, ch 2, 1 dc] in the next chain (this creates your wave peak), 1 dc in each of the next 5 chains, skip 2 chains, 1 dc in each of the next 5 chains. Repeat this sequence across until 1 chain remains, then work 2 dc in the final chain. Turn.
This first row establishes the wave structure — the skipped stitches create the dip at the bottom of each wave, and the ch-2 space creates the peak at the top.
Main Wave Rows
Row 2: Chain 3, turn (counts as first dc). Work 1 dc in the same stitch as your turning chain. Now work 1 dc in each of the next 5 stitches, skip 2 stitches, 1 dc in each of the next 5 stitches, [2 dc, ch 2, 2 dc] in the ch-2 space at the wave peak, 1 dc in each of the next 5 stitches, skip 2 stitches, 1 dc in each of the next 5 stitches. Repeat across the row. At the end of the row, work 2 dc into the top of your turning chain. Turn.
Row 3 onwards: Repeat Row 2. Each row is worked the same way, which is what makes this pattern so enjoyable once you understand it. The wave peaks and valleys align naturally as you work, and you will see the texture build with every row.
Continue repeating Row 2 until your blanket reaches the desired length, changing colors as often or as infrequently as you like.
Finishing Your Blanket
Once you have reached your desired length, fasten off and weave in all your ends securely using your yarn needle. For a clean finish, work your ends in a direction that follows the path of the stitches rather than cutting across them — this keeps the ends from working loose with washing and use.
Border Options
Adding a border to a wave blanket requires a bit of planning because of those natural indentations along the sides. Here are two approaches that work well:
Simple Single Crochet Border: Work 1 sc into each stitch across the top and bottom edges, and work 2 sc into the end of each row along the side edges. When you reach a wave valley, work 3 sc together (sc3tog) to keep things flat. When you reach a wave peak, work 3 sc into the same stitch to fan it out. Repeat all the way around, working [sc, ch 2, sc] into each corner. Join with a slip stitch and fasten off.
Shell Border: For something a little fancier, after completing one round of single crochet, work a second round of shell stitches (5 dc into every other stitch) along the top and bottom edges, and work simple sc or hdc along the side edges where the waves already provide their own texture. This creates a beautiful finished edge that echoes the wave motif.
Color Combination Ideas
One of the most enjoyable aspects of this pattern is playing with color. Here are a few palettes to spark your imagination:
Ocean Waves: Deep navy, teal, aqua, and cream layered in two-row stripes create a breathtaking ocean-inspired blanket. Use the lightest shade at the peaks and the darkest at the valleys for extra drama.
Desert Sunset: Terracotta, dusty rose, warm peach, and ivory work together for a boho-inspired throw that feels warm and earthy. This combination works especially well in a natural cotton yarn.
Classic Neutrals: If you want something that goes with everything, try alternating rows of oatmeal, warm grey, and white. It is simple, timeless, and looks wonderful draped over any couch.
Rainbow Gradient: Work each row in a different color following rainbow order (red, orange, yellow, green, blue, indigo, violet), or use a self-striping yarn to let the color do the work for you. These blankets are particularly popular as children’s gifts.
Monochrome: Even a single-color blanket in this stitch has remarkable depth and texture. Try a deep forest green, a rich burgundy, or a soft dusty blue for a sophisticated, understated look.
Tips for Crocheting Wave Patterns
If you are new to wave or ripple crochet, here are some things to keep in mind that will make your experience much smoother.
Count your stitches at the end of each row. Wave patterns depend on consistent stitch counts to maintain the wave structure. A miscount early on can cause your waves to shift or flatten over several rows. Get into the habit of checking your count after every row while you are still learning the pattern.
Use stitch markers at the peaks and valleys. Place a stitch marker in the ch-2 space at each wave peak and in the pair of skipped stitches at each valley. These become your landmarks, and working into or around them becomes intuitive much more quickly.
Maintain consistent tension. Try to keep your tension even throughout. If you tend to crochet tightly when you are concentrating hard, take a breath and consciously relax your grip on the yarn. Tension that varies from row to row can make the waves look uneven.
Block your finished blanket. Wet or steam blocking works wonders on finished crochet blankets. Spread your finished piece out on a blocking mat, pin it to the correct dimensions, mist it lightly with water, and let it dry completely. Blocking evens out stitches and gives your waves that crisp, defined look you see in professional photographs of this pattern.
Choose your yarn wisely for your climate. If you live somewhere warm, a cotton blend yarn will breathe much better than pure acrylic. If you are making this as a winter blanket, a wool-acrylic blend will add warmth without too much weight.
Video Tutorial
Sometimes written instructions only get you so far, especially with a pattern that has a visual rhythm to it. That is exactly why I have put together a complete video tutorial for the Tonnta Crochet Wave Blanket. In the video, I walk you through every step of the pattern from the foundation chain all the way to the border, including how to manage color changes neatly and how to troubleshoot common mistakes.
You can find the video on the MyCrochetory YouTube channel. I highly recommend watching it alongside the written pattern, especially for your first few rows. Once you see the stitch rhythm in action, the written instructions will make much more sense and you will feel much more confident moving forward on your own.
Whether you prefer to watch and pause, or to read and refer back, you have both options available to you here — so you can learn in whichever way suits you best.
How to Store Your Blanket
Once your blanket is finished and blocked, store it folded or rolled in a breathable bag or bin. Avoid airtight plastic bins for natural fiber yarns, as these can trap moisture. For acrylic, plastic storage is fine. If you are making it as a gift and need to wrap it, roll it loosely rather than folding it sharply — this prevents permanent crease lines in the fabric.
Frequently Asked Questions
Can I use bulky yarn for this pattern? Yes, but you will need to adjust your hook size and your stitch multiple accordingly. Use a 6.00mm or larger hook and check your gauge. The waves will be bolder and the blanket will work up more quickly with bulky yarn.
Can I make this as a baby blanket? Absolutely. For a baby blanket, reduce your starting chain to 87 (which gives you six wave repeats) and work until the blanket measures approximately 36 inches long. Use a soft, machine-washable yarn that is gentle against a baby’s skin.
What if my waves are not lining up? This almost always comes down to a stitch count issue. Frog (unravel) back to the row where things went wrong and recount from the beginning of that row. Make sure you are always working into the ch-2 space at the peak, not into one of the dc stitches adjacent to it.
Can I sell items made from this pattern? Yes! You are welcome to sell finished items made using this free pattern. Please credit MyCrochetory as the pattern designer. The pattern itself may not be resold or reproduced.
