Free Crochet Blanket Pattern: The Cozy Ripple Throw

There is something deeply satisfying about making a blanket by hand. Whether you are crocheting your very first project or you have been working with yarn for decades, a blanket holds a special place in the craft. It is generous, it is practical, and when you finish it, you can wrap yourself in something you made entirely from scratch. This free crochet blanket pattern is designed to be accessible for beginners while still offering enough texture and visual interest to keep experienced makers engaged from the first row to the last.

The Cozy Ripple Throw is a classic ripple-style blanket worked in rows with a simple repeating stitch pattern. The ripple creates beautiful waves of movement across the fabric, and you can customize the color as much or as little as you like. Want a single-color blanket in a gorgeous chunky neutral? Perfect. Want to use up every skein of leftover yarn in your basket and create a scrappy rainbow heirloom? Also perfect. This pattern adapts to whatever vision you bring to it.

Let’s get into everything you need to make this blanket, from materials and gauge to step-by-step instructions and finishing tips.

About This Pattern

This pattern is worked flat, back and forth in rows, using a standard ripple construction. The ripple effect is achieved by alternating increases and decreases at regular intervals across each row. Once you get the rhythm of the stitch repeat, the pattern becomes almost meditative. Many crocheters find ripple blankets to be their favorite “TV project” because the motion is easy to maintain without constantly checking your work.

The finished blanket measures approximately 50 inches wide by 60 inches long at the gauge listed below, which makes it a generous lap blanket or a cozy throw for a twin bed or couch. You can easily adjust the size by adding or removing stitch repeats and working more or fewer rows.

Skill level: Easy to Intermediate
Techniques used: Chain, single crochet, double crochet, slip stitch

Materials You Will Need

Yarn: Approximately 1,200 to 1,500 yards of worsted weight yarn (size 4). You can use one color or as many colors as you like. If you plan to stripe, divide your yardage across your chosen colors however you prefer. Good yarn choices for this blanket include any smooth, washable worsted weight. Wool blends are wonderful because they block beautifully and add drape. Acrylic yarns are budget-friendly, easy to care for, and come in every color imaginable, making them a great choice for a gift blanket.

Hook: US Size J (6.0mm) or the size needed to achieve gauge.

Additional supplies:
Yarn needle for weaving in ends
Scissors
Stitch markers (optional but helpful)
Measuring tape

Gauge

14 double crochets x 8 rows = 4 inches in double crochet.

Gauge is important for this blanket because it determines your finished size. If your gauge is off, your blanket will end up larger or smaller than the dimensions listed. If you are particular about size, work a swatch before casting on. If you are flexible about the finished dimensions, you can skip the swatch and simply adjust your row count at the end.

To check your gauge, chain 20 and work 10 rows of double crochet. Measure the center of your swatch. If your stitches are larger than gauge, go down a hook size. If they are smaller, go up a hook size.

Pattern Notes

Before you begin, here are a few notes that will help the pattern make sense as you work through it.

The foundation chain is a multiple of 14 plus 3. The number 14 is your stitch repeat, which creates one full ripple wave. Each repeat contains a peak and a valley. If you want a wider blanket, add 14 chains. If you want a narrower blanket, subtract 14 chains.

The color changes in this pattern are entirely optional. If you are working with a single color, simply ignore any mention of color changes and keep working with your one yarn.

When changing colors, change at the end of the row during the last pull-through of the final stitch. This keeps your color transitions neat and tidy. Cut the old color and weave in ends as you go, or carry colors up the side if you are working a simple two-color stripe.

Throughout the pattern, “right side” refers to the face of the blanket that you want showing, and “wrong side” refers to the back. For this ripple pattern, both sides look attractive, so this is mostly a matter of personal preference.

Turning chains: At the beginning of each row, chain 3. This chain 3 counts as your first double crochet.

Stitch Glossary

If you are newer to crochet, here is a quick refresher on the stitches used in this pattern.

Chain (ch): The foundation of most crochet projects. Insert your hook into the slip knot, yarn over, and pull through the loop on your hook.

Slip stitch (sl st): Insert hook into stitch, yarn over, pull through both the stitch and the loop on your hook in one motion.

Single crochet (sc): Insert hook into stitch, yarn over and pull up a loop, yarn over and pull through both loops on hook.

Double crochet (dc): Yarn over, insert hook into stitch, yarn over and pull up a loop (3 loops on hook), yarn over and pull through 2 loops (2 loops remain), yarn over and pull through remaining 2 loops.

Two double crochets together (dc2tog) / decrease: Yarn over, insert hook into next stitch, yarn over and pull up a loop, yarn over and pull through 2 loops (2 loops remain on hook). Yarn over, insert hook into the following stitch, yarn over and pull up a loop, yarn over and pull through 2 loops (3 loops on hook). Yarn over and pull through all 3 loops. This joins two stitches into one and creates the valley in your ripple.

Pattern Instructions

Foundation Chain

Chain 199. (This gives you 14 stitches x 14 repeats + 3 for the turning chain. You can count this as 196 + 3, or simply count your chain carefully to reach 199.)

Row 1 (Right Side)

Starting in the 4th chain from the hook (the skipped chains count as your first dc), work 2 dc in that same stitch. This creates your first peak. Dc in the next 5 chains. Dc2tog over the next 2 chains. Dc in the next 5 chains. Work 3 dc in the next chain (this is your peak). Repeat from to across until 14 chains remain before the last chain. Dc in the next 5 chains. Dc2tog over the next 2 chains. Dc in the next 5 chains. Work 2 dc in the final chain.

You should have a row of rippling waves across your foundation. Count your stitches if you like. You should have 199 stitches total.

Turn your work.

Row 2

Chain 3 (counts as first dc). Work 2 dc in the same stitch at the base of your turning chain. Dc in the next 5 stitches. Dc2tog over the next 2 stitches. Dc in the next 5 stitches. Work 3 dc in the next stitch. Repeat from to across, ending with 2 dc in the top of the turning chain from the previous row.

Turn your work.

Rows 3 and Beyond

Repeat Row 2 until your blanket measures approximately 60 inches from the foundation chain, or until you have reached your desired length. The blanket shown uses approximately 120 rows, but your row count may vary depending on your personal tension.

Change colors whenever you like. For a classic stripe effect, change every 2 rows. For a more modern gradient look, change every 10 to 20 rows. For a scrappy style, change whenever you run out of one skein.

Border

A simple border finishes the blanket neatly and gives the edges a polished look.

Round 1: Join your border color (or continue with your working color) to any corner stitch with a slip stitch. Chain 1. Work single crochet evenly around the entire blanket, working 3 sc in each corner stitch to turn the corners neatly. When you reach the starting stitch, slip stitch to join the round.

Round 2: Chain 1. Work single crochet in each stitch around, again working 3 sc in each corner. Slip stitch to join.

Round 3: For a simple shell edge, work skip 2 stitches, work 5 dc in the next stitch, skip 2 stitches, slip stitch in the next stitch around the blanket. Adjust at corners as needed to keep the border lying flat.

Fasten off and weave in your final ends.

If you prefer a simpler border, two or three rounds of single crochet look clean and classic without adding bulk.

Color Ideas and Inspiration

One of the most exciting parts of making a ripple blanket is choosing your color palette. Here are a few ideas to spark your creativity.

Classic Two-Color: Choose a neutral like cream or oatmeal and pair it with a rich jewel tone like navy, forest green, or deep burgundy. Work two rows of each color and alternate throughout the entire blanket.

Rainbow Stripe: Work two rows in each color of the rainbow in order: red, orange, yellow, green, blue, purple. Repeat the sequence until the blanket is complete. This style is cheerful, vibrant, and perfect for a child’s bedroom or a gift that needs to feel celebratory.

Neutral Gradient: Choose five or six shades of the same color family, moving from lightest to darkest. For example, a gray palette might start in white, move through pale gray, medium gray, charcoal, and end in near-black. Work an equal number of rows in each shade for a sophisticated ombre effect.

Scrappy and Stash-Busting: Pull out every worsted weight yarn you own and change colors whenever you feel like it. The ripple stitch is forgiving enough that even random color placement looks intentional. This is a great way to use up single skeins that have been sitting in your stash for years.

Tips for Success

A few practical tips will help your blanket come out beautifully and make the process more enjoyable from start to finish.

Weave in ends as you go. On a striped ripple blanket, you can accumulate a lot of yarn ends very quickly. Weaving them in as you finish each color change means you are never facing a mountain of loose ends at the end of your project.

Keep your tension consistent. Ripple blankets are sensitive to changes in tension because the waves depend on consistent stitch height. If you notice your waves getting tighter or looser as you work, check in with your tension. Many crocheters find that tension changes when they are stressed or tired, so give yourself permission to put the project down and come back to it fresh.

Block your finished blanket. Blocking makes an enormous difference in how a finished crochet blanket looks and feels. For acrylic yarns, wet blocking or steam blocking will relax the fibers and even out your stitches. For wool or wool-blend yarns, soak the blanket in cool water, gently squeeze out the excess water, and lay flat to dry. After blocking, the ripple waves will be more pronounced and the fabric will have a beautiful drape.

Count your stitches occasionally. It is easy to miss a stitch or accidentally add one in the middle of a long row, especially when you are watching something entertaining while you crochet. Every ten rows or so, take a moment to count your stitches and make sure the stitch count matches your starting row. Catching an error early is much easier than trying to fix something many rows later.

Use stitch markers to track your repeats. If you are new to ripple crochet, placing a stitch marker at the peak stitch and the valley stitch of each repeat can help you keep your place until the pattern becomes second nature.

Sizing Options

The base pattern as written creates a generous throw blanket, but you can adjust the size very easily.

For a baby blanket, start with a foundation chain of 87 (84 stitches plus 3 for the turning chain) and work until the piece measures about 36 inches. This will give you a lovely stroller or crib blanket.

For a full-size bed blanket, add 14-stitch repeats to your foundation chain until you reach the width you want, keeping in mind that a wider blanket will also need more yarn. A queen-size blanket typically requires about 60 inches of width, so you would aim for a foundation chain of approximately 213 (210 stitches plus 3).

For a skinny table runner, work just 2 or 3 repeats wide and work as many rows as the length you need. This creates a lovely rippled table runner for holiday decor.

Caring for Your Blanket

How you wash and store your finished blanket depends on the yarn you used. Always check the yarn label for specific care instructions.

Most acrylic yarns are machine washable on a gentle or delicate cycle and can be tumble dried on low. Avoid high heat, which can distort acrylic fibers permanently.

Wool and wool-blend yarns should generally be hand washed in cool water with a gentle wool wash product and laid flat to dry. Never wring or twist wool, as this can cause the fibers to felt.

Cotton yarns are typically very durable and can handle regular machine washing, though they may take longer to dry than other fibers.

Store your finished blanket folded loosely in a breathable bag or bin. Avoid storing yarn or finished projects in plastic bags for long periods, as this can trap moisture.

Sharing Your Finished Blanket

If you make this blanket, sharing it with the crochet community is a wonderful way to celebrate your work and inspire other makers. Take a photo in good natural light, tag your project with the hashtag #CozRippleThrow, and post it to your favorite fiber arts community. Whether you share on Instagram, Ravelry, Pinterest, or a Facebook group, seeing how other makers interpret a pattern with their own color choices is one of the great joys of the craft.

If you give this blanket as a gift, consider including a handwritten note explaining what it is made of and how to care for it. Recipients who do not crochet often do not know that handmade items may need special washing, and a simple card can save a lot of heartbreak.

A Final Note

Crochet blankets take time, and that time is part of what makes them special. Every hour you spend working rows of ripple stitches goes into the finished piece. Every color change is a decision you made. When someone wraps themselves in a blanket you crocheted, they are surrounded by all of that care and attention. That is not something you can buy.

Take your time with this project. Enjoy the process. Put it down when you need to and come back when you are ready. The blanket will wait for you.
