Granny Stripe Crochet Blanket – The Cascades Blanket
There is something deeply satisfying about a project that looks complicated but is actually built on one of the simplest stitches in crochet. The Cascades Blanket is exactly that kind of project. It takes the classic granny stripe — a technique beloved by beginners and experienced crocheters alike — and transforms it into something that feels fresh, modern, and genuinely beautiful. Whether you are picking up a hook for the first time or you have been crocheting for years and want a relaxing project you can work on while watching television, this blanket is the perfect choice.
The name “Cascades” comes from the way the colors flow across the blanket in waves, one stripe melting into the next like water tumbling over rocks. When you choose your yarn colors thoughtfully — working from light to dark or shifting through a gradient palette — the finished blanket genuinely looks like a cascade of color pouring from one corner to another. The effect is stunning, and the secret is that every single row is made with the same basic granny stripe stitch.
This post will walk you through everything you need to know: the materials, the stitch pattern, the color strategy, helpful tips for clean edges and smooth transitions, and guidance on sizing so you can make this blanket as small as a baby blanket or as large as a king-sized throw. By the end, you will have all the information you need to cast on and create something you will be proud of for years to come.
What Is a Granny Stripe?
Before diving into the pattern itself, it helps to understand what a granny stripe actually is. Most crocheters are familiar with the classic granny square — that iconic little motif made in the round with clusters of double crochets separated by chain spaces. The granny stripe takes that exact same concept and works it in rows instead of rounds.
Each row of a granny stripe blanket is made up of clusters of three double crochets separated by a chain-one space, with the clusters worked into the chain spaces of the previous row rather than into the individual stitches. This creates the signature open, textured look that is so characteristic of granny-style crochet, but instead of building a square, you are building a horizontal stripe that grows row by row into a blanket.
The granny stripe is sometimes also called the granny ripple, though a true ripple has increases and decreases worked in to create a wave shape. The version used in the Cascades Blanket is a straight granny stripe — the edges stay flat and even, which makes it beginner-friendly and gives the blanket a clean, polished look.
Materials You Will Need
One of the best things about this blanket is that it does not require anything fancy. The materials are simple and widely available.
Yarn: You will need a worsted weight yarn, which is sometimes labeled as size 4 on the yarn weight scale. Worsted weight is ideal for this pattern because it gives the clusters enough body to look defined without being too heavy. A smooth yarn in a single ply or a tightly spun construction will show off the stitch detail beautifully. Acrylic yarn is a wonderful choice for beginners because it is machine washable, affordable, and comes in an enormous range of colors — which matters a great deal for a project like this one. Cotton yarns also work well if you want a blanket with a little more drape and breathability, which is lovely for spring and summer throws.
For a standard lap blanket measuring approximately 50 by 60 inches, you should plan for roughly 2,000 to 2,500 yards of yarn total across all your colors. A baby blanket will use significantly less — around 800 to 1,000 yards — while a large throw or bed blanket will require more.
Hook: A 5.0mm or 5.5mm crochet hook is the standard recommendation for worsted weight yarn, though your gauge may vary slightly depending on how tightly or loosely you crochet. Always check your gauge before starting if the size of your finished blanket matters to you.
Additional supplies: You will need a yarn needle for weaving in your ends, scissors, and stitch markers if you want to mark the beginning of each row or track your color changes. A row counter — either a physical one or an app on your phone — is helpful for keeping track of how many rows you have completed in each color.
Choosing Your Colors
Color selection is really where the magic of the Cascades Blanket happens, and it is worth spending some time thinking about this before you buy your yarn.
The most striking versions of this blanket use a gradient or ombre approach, where the colors transition gradually from one end of the spectrum to another. You might move from deep navy through cobalt, sky blue, and pale aqua, for example. Or you might work through an autumnal palette of rust, burnt orange, gold, and cream. The key to making the cascade effect really land is to choose colors that flow into one another naturally, where each shade relates to the one before and after it.
That said, you absolutely do not need to stick to a gradient. The Cascades Blanket also looks wonderful in bold, contrasting stripes — think a classic combination of mustard yellow, teal, and ivory, or a rich jewel-toned palette of emerald, plum, and sapphire. When you use high-contrast colors, the stitch texture becomes the star rather than the color flow, and the result is graphic and eye-catching.
Another popular approach is to use a self-striping or gradient yarn for part of the blanket and then add solid-colored stripes as accents. This gives you some of the gradient effect without having to manage multiple yarn balls at once, which can be helpful if you are newer to multi-color crochet.
A good rule of thumb when selecting colors: lay out your yarn skeins side by side and step back a few feet to see how they look together at a distance. Colors that seem very different up close can blend beautifully when you view them from across the room, and that is how your finished blanket will most often be seen.
The Pattern
Foundation Chain
To begin, you will need to create a foundation chain that determines the width of your blanket. The granny stripe pattern has a repeat of 3 stitches plus a turning chain, so your foundation chain should be a multiple of 3, plus 4 for the turning chain.
For a standard lap blanket that is approximately 50 inches wide, chain 150, then add 4, for a total of 154 chains. For a baby blanket around 30 inches wide, chain 90 plus 4, for a total of 94 chains.
Row 1 (Foundation Row)
Skip the first 4 chains from your hook (these 4 chains count as your first double crochet plus chain 1). Work 2 double crochets into the 5th chain from your hook. This creates your first cluster. Skip 2 chains, then work 3 double crochets into the next chain. Continue across the row, skipping 2 chains and working 3 double crochets into the next chain, until you have 2 chains remaining. Skip 1 chain, then work 2 double crochets plus chain 1 plus 1 double crochet into the last chain. This creates a half-cluster at each end that keeps your edges straight.
Row 2 Onward (Granny Stripe Pattern)
Chain 3 and turn your work. Work 2 double crochets into the first chain-1 space (the space created by the chain-1 in your previous row). Chain 1. Work 3 double crochets into the next chain-2 space (the space between clusters). Chain 1. Continue across the row, working 3 double crochets into each chain space, separating each cluster with a chain 1, until you reach the last space at the end of the row. Work 2 double crochets plus chain 1 plus 1 double crochet into the final chain space to create your edge.
Repeat row 2 for every subsequent row. That is the entire pattern. Every row is the same.
Changing Colors
To change to a new color, work across the row as normal until you reach the last yarn-over of the last stitch in the row. On that final yarn-over, pull through with the new color instead of the old one. This creates a smooth color transition without a visible jog. Cut the old color, leaving a tail of about 6 inches, and begin working the next row with the new color.
For the Cascades Blanket, a typical stripe width is 4 to 6 rows per color. Narrower stripes of 2 rows give a more gradient, blended look. Wider stripes of 8 to 10 rows create a bolder, more graphic effect. Experiment with what appeals to you.
Tips for a Beautiful Finished Blanket
Consistent tension is the most important factor in how your blanket will look. If your tension changes significantly from one row to the next or one color to the next, you may notice your blanket pulling or ruffling. Try to relax your grip and work at the same pace throughout the project. If you know you crochet tighter when you are stressed or tired, put the blanket down and come back to it when you are feeling relaxed.
Weaving in your ends as you go will save you an enormous amount of time at the end. Rather than cutting every color and leaving all those tails to deal with later, take a moment at each color change to weave in the tails from the previous color before moving on. Threading them through several stitches in the wrong side of the blanket will secure them firmly.
Blocking your finished blanket can make a significant difference in the final appearance. Wet blocking — soaking the blanket in cool water, pressing out the excess moisture, and laying it flat to dry — relaxes the fibers and evens out any tension inconsistencies. It also opens up the stitch pattern beautifully, making the clusters look more defined and the blanket feel softer. If you have used an acrylic yarn, steam blocking (hovering a steam iron over the blanket without touching it) can achieve similar results.
Working a border is optional but adds a lovely finishing touch. A simple single crochet border worked one or two rounds around all four edges of the blanket tidies up the sides and gives the whole project a polished, intentional look. You might choose to work the border in a neutral color that appears throughout the blanket, or in a contrasting accent color that frames the design.
Sizing Guide
The Cascades Blanket can be made in virtually any size by adjusting your foundation chain and the number of rows you work.
For a baby blanket, aim for approximately 30 by 36 inches. A starting chain of 94 and around 80 to 90 rows will get you there.
For a lap blanket or sofa throw, 50 by 60 inches is a popular and useful size. Start with a chain of 154 and work until your blanket reaches about 60 inches in length.
For a full or queen bed throw, you are looking at around 60 by 80 inches or larger. Increase your starting chain accordingly (around 184 for 60 inches wide) and work as many rows as needed.
Because the granny stripe is essentially infinite — you just keep adding rows — the length of your blanket is entirely up to you. Many crocheters work until they run out of yarn or until the blanket is the size they want, which makes it a wonderfully flexible project.
Why the Cascades Blanket Makes a Great Gift
If you crochet for others, this blanket is one of the most rewarding gifts you can make. It is large enough to feel substantial and generous, but the repetitive stitch pattern means you can work on it while chatting or listening to music without losing your place. The color customization options are essentially endless, which means you can tailor every blanket to the specific person you are making it for — their favorite colors, their home decor, the season of their birth.
Baby blankets made in the Cascades style are especially beloved. A soft gradient of pastel colors in gentle, hypoallergenic yarn makes a gift that is both practical and sentimental. Wedding and housewarming gifts in neutral tones — cream, warm grey, oatmeal — feel luxurious and considered. A chunky version made in deep, rich tones makes a wonderful gift for anyone who loves cozy, hygge-style interiors.
There is also something meaningful about the time that goes into a hand-crocheted blanket. Every row represents a moment you spent thinking about the person you were making it for. That intention, woven quite literally into every stitch, is something no shop-bought blanket can replicate.
Joining the Granny Stripe Community
One of the loveliest things about the granny stripe pattern is how widely it is loved in the crochet community. If you share your work in progress or your finished Cascades Blanket on social media, you will find an enormous and enthusiastic audience of fellow crocheters who share color suggestions, tips, and encouragement. Searching for the granny stripe or granny stripe blanket on platforms like Instagram, Pinterest, or Ravelry will return thousands of beautiful examples to inspire your own color choices.
Many crocheters also use this pattern as a way to use up yarn from their stash — those leftover partial skeins from previous projects that are not quite enough for anything on their own. A random-striped Cascades Blanket made from stash yarn, with no plan other than to use what you have, can be one of the most joyful and surprising projects you will ever make. The colors you would never have thought to put together on purpose sometimes create something extraordinary when you simply let the stash decide.
Final Thoughts
The Cascades Blanket is proof that you do not need a complicated pattern to make something genuinely beautiful. The granny stripe stitch is one of crochet’s most enduring techniques for good reason — it is approachable, rhythmic, and deeply satisfying to work row after row. The result is a blanket with texture, warmth, color, and character.
Whether you are a beginner looking for your first big project, an experienced crocheter wanting a relaxing make, or someone searching for the perfect handmade gift, the Cascades Blanket delivers on every count. Choose your colors, cast on your foundation chain, and let the rows carry you forward. You will be surprised how quickly a blanket comes together when every stitch feels this good to make.
Happy crocheting.
