Free Crochet Pattern: The Cozy Ripple Blanket
There is something deeply satisfying about a ripple blanket. The way the yarn moves in waves across your hook, the rhythm that builds once your hands know the pattern, the finished product that looks far more complicated than the hours you actually spent making it — all of it adds up to one of the most rewarding projects a crocheter can take on. This free crochet pattern for the Cozy Ripple Blanket will walk you through every step, from choosing your yarn to weaving in your last end, so that whether you are a confident beginner or a seasoned maker looking for a satisfying weekend project, you will have everything you need right here.
What Makes a Ripple Blanket So Special?
Before we dive into the pattern itself, it is worth taking a moment to appreciate why ripple blankets have remained so beloved for generations. The chevron or ripple stitch has roots in traditional granny-square and Afghan traditions, and it has never gone out of style because it manages to look both classic and modern at once. A single-color ripple blanket in a neutral tone feels fresh and Scandinavian. A multicolor striped version feels bohemian and joyful. You can drape it over a nursery crib, pile it on a couch, or wrap it around your shoulders on a cold morning, and it will feel right every single time.
The other reason ripple blankets are so popular is that they teach you something important about crochet: increase and decrease stitches are not scary. Many beginners avoid patterns that mention them, assuming the technique is complicated. But in a ripple stitch, increases and decreases are baked into every single row, and after just a few repeats you will be doing them without even thinking about it. By the time you finish this blanket, you will have built real confidence with shaping — a skill that will serve you in countless future projects.
Materials You Will Need
Getting your materials together before you start is always worth the few extra minutes. Nothing interrupts a crochet flow quite like running out of yarn mid-row.
For this blanket, you will need a worsted weight yarn, which is sometimes labeled as “medium” or “4” on the yarn label. Worsted is the sweet spot for blankets — it works up quickly, holds its shape beautifully, and comes in an enormous range of colors. For a throw-sized blanket measuring approximately 50 by 60 inches, you will need roughly 1,800 to 2,000 yards of yarn total. If you are making it in a single color, that is four to five skeins of a standard 400-yard worsted weight. If you are planning to stripe it, divide your yardage however you like across your chosen colors.
Some wonderful yarn choices for this pattern include Lion Brand Pound of Love, which is a budget-friendly acrylic that comes in a huge variety of colors and is machine washable — an important quality in a blanket. Paintbox Yarns Simply DK is slightly lighter and gives a beautiful drape. For those who want to invest in something special, Malabrigo Rios is a superwash merino that produces stunning stitch definition and feels absolutely luxurious against the skin.
You will also need a size 5.5mm crochet hook, or an H/8 hook in US sizing. If you tend to crochet tightly, size up to a 6mm. If your tension is naturally loose, try a 5mm. The goal is a fabric that is soft and slightly draping rather than stiff.
Finally, have a tapestry needle on hand for weaving in ends, and a pair of scissors. If you are working in multiple colors, a few stitch markers can be helpful for tracking your repeats as you learn the pattern, though they become unnecessary once the stitch rhythm is in your hands.
Gauge
For this pattern, your gauge should be approximately 14 double crochet stitches and 7 rows equal 4 inches, worked in double crochet. Because this is a blanket and the finished dimensions are flexible, gauge is not critical — but if you are significantly off, your blanket will end up much larger or smaller than the estimated size. Take five minutes to make a small swatch before casting on and you will thank yourself later.
Pattern Notes and Abbreviations
This pattern is written in US crochet terminology. Here are the abbreviations used throughout:
Ch means chain. Sl st means slip stitch. Sc means single crochet. Dc means double crochet. St means stitch. Sk means skip. Rep means repeat. Beg means beginning.
The ripple pattern works across a multiple of 14 stitches, plus 3 for the turning chain. The foundation chain in this pattern is 199 stitches, which gives you 14 ripple repeats and creates a blanket approximately 50 inches wide. You can adjust the width by adding or subtracting multiples of 14 stitches.
When counting your stitches at the end of each row, do not count the turning chain as a stitch. The stitch count will remain the same from row to row.
The Pattern
Foundation Chain
Chain 199. This is your starting chain. Take a moment to count it carefully before continuing. If you are off by even one stitch the pattern will not align correctly, so it is worth the patience now.
Row 1 — Setup Row
Double crochet in the fourth chain from your hook. This skipped chain counts as your first double crochet. Double crochet in each of the next 4 chains (6 dc total including the skipped chain).
Now you are going to work the increase point of your first ripple peak. Work 3 double crochet all into the same chain stitch. That center stitch of the three is your peak.
Double crochet in each of the next 5 chains.
Now you are going to work the valley, which is your decrease point. Skip the next 2 chains, then double crochet in each of the next 5 chains.
Work 3 double crochet into the next stitch to create your next peak. Double crochet in each of the following 5 stitches. Skip 2, double crochet in 5. Repeat this sequence — peak, 5 dc, valley, 5 dc — across the row until 6 stitches remain before the end of the chain. Double crochet in each of those last 6 stitches, then work 2 double crochet into the very last chain.
Turn your work.
Row 2 and All Following Rows
Chain 3. This turning chain counts as your first double crochet.
Double crochet in each of the next 5 stitches. At the peak of the ripple — the center stitch of the 3 dc cluster from the row below — work 3 double crochet into that center stitch. Double crochet in each of the next 5 stitches. At the valley, skip 2 stitches, double crochet in each of the next 5 stitches. Repeat the peak and valley sequence across the row until 6 stitches remain. Double crochet in each of those last 6 stitches, work 2 double crochet into the top of the turning chain from the previous row.
Turn.
Repeat Row 2 for the entire length of the blanket. Continue until your blanket measures approximately 60 inches from end to end, or until you have used the desired amount of yarn. The more rows you add, the longer and cozier your blanket becomes.
How to Add Stripes
One of the most beautiful things about the ripple pattern is how it interacts with color. If you want to work this blanket in stripes, simply change your yarn color at the end of any row. To make a clean color join, work the last stitch of your final row with the current color until you have two loops on your hook. Then pull through with the new color and turn as normal. This gives you a neat, uninterrupted line of color at each stripe edge.
Classic stripe sequences that work beautifully with this pattern include two rows of each color cycling through a palette of three or four shades, or single rows that shift gradually from one hue to another for an ombre effect. You can also do bold, wide stripes — ten or twelve rows each — for a graphic, modern look.
When you join a new color, leave a tail of about six inches on both the old and the new yarn. You will weave these in later with your tapestry needle. Try to weave ends in along the spine of stitches in a direction and then back in another direction so they cannot pull free.
Tips for a Beautiful Finished Blanket
There are a few habits that will make a noticeable difference in the quality of your finished blanket, and they are all easy to build once you know about them.
First, maintain consistent tension throughout the project. This is especially important in a pattern where your stitch count stays the same row after row. If your tension fluctuates — tighter when you are stressed, looser when you are relaxed — the blanket can develop a wavy or puckered quality that blocking will not entirely fix. If you notice your tension drifting, take a break and come back with fresh hands.
Second, count your stitches at the end of every few rows, at least in the beginning. The ripple pattern is forgiving in many ways, but a miscounted peak or valley will throw off your alignment and create a diagonal drift that becomes more noticeable the further you go. A quick count takes thirty seconds and saves you the heartbreak of frogging ten rows of work.
Third, block your finished blanket. Blocking is the process of wetting or steaming your finished piece and then pinning it out to its correct dimensions while it dries. For acrylic yarn, you can use a steam iron held just above the surface (not touching it) to relax the fibers. For wool or natural fibers, soak the blanket in cool water, gently squeeze out the moisture, then lay it flat and pin it to shape. Blocking smooths out any tension inconsistencies, evens the stitches, and makes the finished fabric look polished and intentional. It is one of the most transformative steps in any crochet project and is always worth the time.
Finishing the Blanket
Once your blanket has reached the desired length, fasten off your yarn by cutting it with about a six-inch tail and pulling the tail through the last loop on your hook to secure it.
Weave in all your ends with your tapestry needle, running each tail along the back of several stitches in one direction and then back along a slightly different path. Give each woven end a gentle tug to make sure it is secure, and trim any excess close to the fabric.
If you want to add a border, a simple single crochet edging all the way around the blanket is a lovely finishing touch that also tidies up the edges of the ripple. Join your yarn at any corner, work 3 single crochet into the corner stitch to turn it neatly, single crochet evenly along the edge, and repeat around all four sides. You can do a single round in the same color as your blanket for a subtle finish, or choose a contrasting color to frame the piece.
Sizing Adjustments
The great flexibility of this pattern is how easily you can resize it. For a baby blanket, cast on 85 stitches (6 ripple repeats) and work to approximately 36 inches long. For a full bed throw, cast on 283 stitches (20 ripple repeats) and continue to 72 or 80 inches. For a lapghan or wheelchair blanket, the 50 by 60-inch throw size given in this pattern is exactly right as written.
The formula is simple: multiply the number of ripple repeats you want by 14, then add 3 for the turning chain. This gives you your foundation chain number every time.
Caring for Your Ripple Blanket
How you wash and store your blanket will determine how long it keeps its shape and softness. For acrylic yarn, machine washing on a gentle cycle in cool water is perfectly safe. Lay the blanket flat or tumble dry on low heat. Avoid high heat, which can distort synthetic fibers. For wool or wool-blend yarn, hand wash in cool water with a gentle wool wash and lay flat to dry. Never wring or twist a wet wool item.
Store your blanket folded rather than rolled if possible, and keep it away from direct sunlight for extended periods, which can fade colors over time. With basic care, a well-made crochet blanket will last for decades.
A Few Words Before You Start
Ripple blankets are the kind of project that people start and never want to stop. The rhythm of the stitch is genuinely meditative once you find your flow, and the visual reward of watching the waves build row by row is deeply satisfying. Many makers report that their ripple blanket became their go-to travel project, their evening unwinding ritual, or the first piece they ever felt genuinely proud to gift.
If you make this blanket, share it. Post a photo in a crochet group, tag a friend who might love the pattern, or give the finished piece to someone who needs a little warmth. Handmade things carry something that bought things simply cannot — the hours, the care, the intention. A ripple blanket made with your own hands is a gift that will be kept and used and remembered.
Happy crocheting.
