Learn Granny Squares: Make Blankets, Bags & More

There is something deeply satisfying about learning a craft that connects you to generations of makers who came before you. Granny squares are exactly that kind of craft. These small, modular crochet units have been stitched by grandmothers, teenagers, textile artists, and absolute beginners for well over a century, and their popularity has never really dimmed. If you have ever wanted to learn granny squares but felt intimidated by the idea, or if you already know the basics and are wondering what to actually do with them, this guide is for you.

We will walk through everything from the very first slip knot to assembling a full-size blanket, a structured bag, and a handful of smaller projects that will keep you busy and inspired for months. By the time you finish reading, you will understand not only how to make a granny square but why this humble little motif is one of the most versatile tools in a crafter’s toolkit.

What Exactly Is a Granny Square?

A granny square is a small, flat crochet motif — traditionally square in shape — worked in the round from the center outward. It is built using a combination of chain stitches, double crochet clusters, and corner spaces, which give it that distinctive blocky, lacy look. The classic version is usually three to four rounds and measures somewhere between four and six inches across, though the size varies depending on your yarn weight and hook size.

The modular nature of granny squares is what makes them so powerful. You work each one individually, then join them together to create something much larger. This means you can work on a project in small, manageable sessions — on your lunch break, while watching television, while waiting at the doctor’s office — and gradually build toward something impressive without ever needing to hold a massive piece of fabric in your lap.

Granny squares are also a brilliant way to use up yarn scraps. Many makers use a different color for each round or each square, turning leftover bits of yarn into a cohesive, colorful patchwork. This waste-not philosophy is part of what gave granny squares their original appeal and part of what keeps them relevant in a crafting culture that is increasingly interested in sustainability.

What You Need to Get Started

You do not need much to begin, which is another reason granny squares are such a popular entry point into crochet.

Yarn: Any weight of yarn will work, but worsted weight (labeled as size 4 or medium weight) is the most forgiving for beginners. It is thick enough to see your stitches clearly and works up quickly. For a traditional look, choose 100% acrylic or a wool-acrylic blend, both of which are durable and easy to wash. If you want a softer drape for a blanket, cotton-acrylic blends are a lovely choice.

Crochet hook: For worsted weight yarn, a 5mm (US size H/8) or 5.5mm (US size I/9) hook is a solid starting point. The hook you choose affects the size and density of your squares, so if your squares are coming out too tight or too open, adjusting your hook size is usually the fix.

Scissors and a yarn needle: You will be cutting and weaving in a lot of ends, so keep these handy. A blunt-tipped tapestry needle is ideal for weaving in ends without splitting the yarn.

Stitch markers: Optional but helpful, especially when you are learning to identify corners.

That is genuinely all you need. No special equipment, no expensive setup.

How to Make a Classic Granny Square: Step by Step

The traditional granny square pattern has been passed down in countless variations, but the structure is always the same. Here is a clear walkthrough of the classic version.

Starting the center

Make a slip knot and chain 4. Join with a slip stitch to form a ring. This small loop is the foundation of your square.

Round 1

Chain 3 (this counts as your first double crochet). Work 2 more double crochets into the ring. Chain 2. Work 3 double crochets into the ring. Chain 2. Repeat twice more so you have four clusters of 3 double crochets separated by four chain-2 corner spaces. Join with a slip stitch to the top of the beginning chain-3. You now have the very center of your square with four defined corners.

Round 2

Slip stitch into the corner space. Chain 3 and work 2 double crochets into the same corner space, then chain 2 and work 3 more double crochets into the same space (this creates the corner). Chain 1. Move to the next corner space and repeat the corner. Continue around all four corners with a chain-1 between each one. Join with a slip stitch.

Round 3

Slip stitch into the corner space. Chain 3, work 2 double crochets, chain 2, and 3 double crochets all into the same corner (corner made). Chain 1. Work 3 double crochets into the chain-1 space on the side (this is your side cluster). Chain 1. Make the corner in the next corner space. Continue around. Join.

Round 4

Repeat the same logic — corners get the full corner treatment, and each chain-1 space along the sides gets a cluster of 3 double crochets with chain-1 spaces in between.

Each round adds one more cluster along each side, so as you keep adding rounds, your square grows. A finished four-round square in worsted weight yarn on a 5mm hook should measure roughly five to six inches.

Finishing

When you reach the end of your final round, fasten off and leave a tail of about six inches. Weave the tail in with your yarn needle, threading it through the backs of nearby stitches and changing direction once or twice to lock it in place. Trim.

The Art of Color: Choosing Your Palette

One of the most enjoyable parts of making granny squares is playing with color. There is no wrong approach, but a few strategies can help you create a finished project that feels cohesive rather than chaotic.

A solid or tonal palette uses two or three shades from the same color family — think cream, soft gold, and rust — for a calm, coordinated look that works well in modern and minimalist interiors. A rainbow approach uses every color in a roughly equal way, which gives a cheerful, retro feel. If you are working from a scrap pile, you can unify wildly different colors by using one consistent color for the final round of every square — this acts as a visual frame and makes even clashing hues look intentional.

When planning a multicolored blanket, it is worth laying your finished squares out on the floor before joining them to audition different arrangements. Moving them around until colors are evenly distributed takes just a few minutes and makes a big difference in the final result.

Joining Your Squares: Three Methods to Know

Joining is where individual squares become something greater. There are several methods, each with a different look and feel.

Slip stitch join (flat seam): Hold two squares with right sides facing each other and use your hook and yarn to slip stitch through the back loops of both edges simultaneously. This creates a raised seam on the back that is barely visible from the front — a clean, tidy look that works well for blankets and bags.

Single crochet join (visible ridge): Work the same as above but with single crochet instead of slip stitch. This creates a more pronounced ridge, which some makers deliberately place on the right side of the work for a textured, decorative effect. It is a great choice when joining with a contrasting color.

Flat join with yarn needle (sewn seam): Thread a length of yarn onto your tapestry needle and use a whip stitch or mattress stitch to sew the edges together. This is the most invisible join but also the most time-consuming. It works beautifully for projects that will be handled gently, like wall hangings or decorative pillows.

For your first large project, the slip stitch join is the most practical — it is fast, creates a sturdy seam, and looks neat.

Project 1: The Classic Granny Square Blanket

A granny square blanket is perhaps the most iconic project in all of crochet, and for good reason. It is supremely satisfying to make, endlessly customizable, and genuinely useful. A throw-size blanket (roughly 50 by 60 inches) made from five-inch squares requires approximately 120 squares — 10 across and 12 down.

This sounds like a lot, but the beauty of the format is that you never feel overwhelmed. Each square takes about fifteen to twenty minutes at a comfortable pace, which means you can make six or eight in a single evening and feel genuine progress with every session.

Planning your blanket

Before you cast on a single stitch, decide on your color story and your layout. Sketch a simple grid on paper and color it in — this does not have to be elaborate, just enough to give you a plan. Decide whether you want a border and, if so, what color. A border in a single coordinating color unifies the whole piece and gives it a polished, finished edge.

Making and joining

Work your squares in batches. Many makers find it helpful to make all the squares first, then join — this “make then assemble” approach lets you adjust the layout right up until the last moment. Others prefer joining-as-you-go, which means attaching each new square to the existing piece as you complete it. Joining-as-you-go eliminates the separate seaming step but requires more planning upfront.

Adding a border

Once all your squares are joined, work one or two rounds of single crochet around the entire blanket, paying extra attention to the corners. Increase at each corner by working three stitches into the corner stitch to keep the blanket lying flat. A final round of reverse single crochet (also called crab stitch) gives a beautiful, rope-like edge.

Block your blanket by misting it lightly with water, shaping it squarely, and letting it dry flat — this step makes a dramatic difference in how smooth and even the finished piece looks.

Project 2: A Granny Square Bag

Bags are one of the most exciting ways to use granny squares because they transform a soft textile craft into something structural and functional. A basic rectangular tote requires just twelve to sixteen squares depending on the size you want.

Construction

For a simple tote, work four squares across and three rows down for the front panel, and repeat for the back panel. Work two more squares for the base (or simply seam the bottom panels together). Join all panels together using your preferred seaming method.

For the handles, crochet two long chains of single crochet, approximately 20 to 24 inches, then fold each one and attach to the top edges of the bag. Alternatively, you can purchase leather or canvas handles from a craft store and sew them on for a more polished, commercial finish.

Lining your bag

Granny squares are wonderful but not particularly dense — light passes through the gaps, and small items can slip through. Lining your bag is easy and transforms it entirely. Cut two rectangles of cotton fabric to match your front and back panels plus a half-inch seam allowance. Sew them together on three sides, fold the top raw edge down, and slip the lining inside the bag. Whip stitch the lining to the top edge.

A lined granny square bag is sturdy enough for farmers market shopping, beach trips, or everyday errands.

Project 3: A Patchwork Cushion Cover

A cushion cover requires just eight squares — four for the front and four for the back — making it an ideal weekend project for someone who wants a finished result quickly.

Join four squares into a two-by-two arrangement for each side. With right sides facing, seam three sides together. Turn right side out, insert a 16-inch cushion form or pillow insert, and seam the fourth side closed. A zipper or a simple overlapping back panel makes removing the cover for washing much easier.

Cushion covers are fantastic practice pieces because they let you experiment with color combinations and joining methods on a small scale before committing to a full blanket.

Project 4: Granny Square Table Runner

A table runner using a single row of five to seven large squares (or two rows of smaller ones) is an elegant home accessory that works up in just a few hours. Use a neutral palette with a pop of color for seasonal decorating — swap out runners to match the time of year.

Because a table runner is flat and decorative rather than functional, you can also use finer yarn here. Fingering weight cotton in a soft ecru or dusty sage gives a delicate, heirloom quality that makes the piece feel special.

Tips for Making Your Squares Consistently

One challenge beginners face is that their early squares are a different size from their later ones as their tension changes with growing confidence and muscle memory. Here are a few things that help.

Block every square before joining, not just the finished project. This evens out tension differences significantly. If squares are still varying in size, use your hook to gently stretch smaller ones and ease larger ones while they are damp from blocking.

Count your stitches at the end of each round. A correctly made square has 12 stitches per side on round 3, 15 per side on round 4, and so on — three extra per side per round. If your stitch count is off, you have likely missed a chain space or added an extra cluster somewhere.

Take breaks. Tension tightens when you are tired or stressed. Many experienced crocheters find their squares made in relaxed evening sessions are more even than those made in hurried morning moments.

Beyond the Square: Exploring Other Shapes

Once you are comfortable with the classic square, a whole world of variations opens up. Hexagon motifs can be joined to create a honeycomb pattern with a completely different visual texture. Round motifs, called doilies in their most elaborate form, can be joined into a striking bohemian blanket. Triangles can be arranged point-to-point for a geometric, graphic effect.

Flower-center granny squares replace the simple chain ring with a small flower shape — petals worked in a contrasting color before the regular granny rounds continue around them. Solid granny squares fill in all the chain spaces so the final piece is dense and opaque rather than lacy, making them ideal for bags, potholders, and items that need more structure.

The traditional granny square is essentially a framework, and once you understand the logic behind it, you can adapt it endlessly.

Caring for Your Finished Projects

Most acrylic and acrylic-blend granny square projects are machine washable on a gentle cycle, which is one of the reasons these yarns are so popular for blankets that will actually be used. Wash in cool water and lay flat to dry — machine drying can cause some yarns to pill or distort.

Pure wool squares should be hand washed in cool water with a gentle wool wash and laid flat to dry. Never wring or agitate wool — it will felt.

Cotton granny squares (great for dishcloths, market bags, and summer throws) are often the most durable of all and can typically handle machine washing and drying without issue.

The Community Side of Granny Squares

One thing that makes granny squares unusual among craft projects is the culture around them. Because they are so portable and modular, they have long been made communally — charity blankets assembled from squares donated by different makers, swap groups where participants mail each other finished squares, and online communities where people post their daily square counts and color experiments.

If you have ever struggled to finish a project because motivation fades in the long middle stretch, joining a granny square community can genuinely change your crafting experience. The accountability, the shared enthusiasm, and the steady stream of inspiration from other makers’ work can carry you through moments when your own pile of squares feels impossibly far from done.

Search for granny square alongs, crochet-alongs, or CALs on any major crafting platform and you will find no shortage of organized, friendly groups working toward the same goal.

A Note on Learning Resources

If you found any part of the stitch instructions above confusing, do not be discouraged — written crochet instructions have a learning curve of their own, and many people find that watching the stitches happen in real time is far more intuitive. Video tutorials on platforms like YouTube are extraordinarily useful for visual learners, and searching for “beginner granny square tutorial” will return dozens of high-quality, clearly filmed options.

Once you have the basic square down from watching, return to written patterns — they are the standard format for published designs and learning to read them confidently opens up an enormous library of projects.

Final Thoughts

The granny square has survived every shift in fashion and trend because it is, at its core, a deeply practical and pleasurable thing to make. It is small enough to feel achievable, flexible enough to become almost anything, and colorful enough to keep your interest through hundreds of repetitions. It connects you to a long tradition of thrifty, creative textile making, and it produces something tangible and beautiful that you can use, give away, or pass on.
