Crochet Granny Hexagon Blanket: Your Complete Guide to a Timeless Classic
There is something deeply satisfying about a granny hexagon blanket. Unlike the traditional square granny, the hexagon version brings a geometric elegance that feels both modern and nostalgic at the same time. Whether you are a seasoned crocheter looking for your next project or a beginner who has just mastered the basics, this guide will walk you through everything you need to know — from choosing your yarn to joining your hexagons and finishing your blanket with a polished edge.
What Is a Crochet Granny Hexagon Blanket?
A granny hexagon is a six-sided crochet motif worked in the round, typically built up with clusters of double crochet stitches separated by chain spaces — the same basic construction language as a granny square, but shaped into a hexagon through strategic increases at six corners rather than four. When dozens of these little motifs are joined together, the result is a blanket with a honeycomb-like appearance that lies flat, drapes beautifully, and has virtually no wasted space between pieces.
The design has roots in the long history of motif crochet, which stretches back to the 19th century when crafters would work small pieces of lace or colorwork and stitch them together into larger textiles. Today, granny hexagon blankets are beloved for their versatility — they work beautifully in single-color schemes, gradient yarn, scrap yarn stashes, or bold contrasting combinations. They also make wonderful gifts, heirloom pieces, baby blankets, lap blankets, and full-size throws.
Why Choose a Hexagon Over a Square?
This is a question that comes up often, and the answer really comes down to personal preference and the look you want to achieve. Granny squares are classic, endlessly popular, and slightly easier for absolute beginners to count because four corners are more intuitive than six. But the hexagon has its own set of compelling advantages.
First, hexagons tessellate naturally — meaning they fit together without gaps when joined correctly, creating a tighter fabric with a more cohesive look. The seams between hexagons form pleasing lines that radiate outward like a honeycomb, giving the finished blanket a visual rhythm that squares can’t quite replicate.
Second, hexagons tend to be more forgiving along the edges. Because the six-sided shape distributes the fabric more evenly, blankets made from hexagons often have a more natural drape and less tendency to curl at the corners the way some square-based blankets can.
Third, and perhaps most practically, working hexagons is simply fun in a different way. There is something meditative about rotating through six corners instead of four — a small variation that keeps your hands engaged without requiring intense concentration.
Materials You Will Need
Before you start crocheting, gathering the right materials will make the entire process smoother and more enjoyable.
Yarn is your most important choice. For a classic granny hexagon blanket, worsted weight yarn (also labeled as size 4) is the most commonly recommended option. It works up quickly, is available in hundreds of colors, and creates a fabric with a nice drape and warmth. Popular choices include Lion Brand Pound of Love, Red Heart Super Saver, Paintbox Simply DK (if you prefer a slightly lighter weight), or any acrylic, cotton, or acrylic-cotton blend yarn you enjoy working with. If you are using scrap yarn, make sure all your skeins are roughly the same weight so your hexagons come out the same size.
Hook size should match your yarn’s recommended gauge, but for a traditional crocheted motif you may want to go up a half or full hook size to give your stitches a looser, more open appearance. For worsted weight yarn, a 5mm (H) or 5.5mm (I) hook is a common starting point.
Notions include a yarn needle for weaving in ends and joining motifs if you choose a sewn join, scissors, stitch markers to mark your starting corner if needed, and a blocking mat with rust-proof pins if you plan to block your finished hexagons.
Quantity depends entirely on the size blanket you want. A baby blanket might use somewhere between 19 and 37 hexagons, while a generous lap blanket or throw requires anywhere from 61 to well over 100 motifs. It is always worth making one test hexagon to measure its finished diameter before calculating your total yarn needs.
How to Crochet a Basic Granny Hexagon
The following pattern creates a classic granny hexagon using double crochet clusters and chain spaces. It assumes you know how to make a slip knot, magic ring (or chain ring), chain, slip stitch, and double crochet.
Abbreviations used:
ch = chain, sl st = slip stitch, dc = double crochet, sp = space, st = stitch
Round 1: Create a magic ring (or ch 4 and join to form a ring). Ch 3 (counts as first dc), work 2 dc into the ring, ch 2. Work 3 dc into the ring, ch 2. Repeat from * four more times. You will have six clusters of 3 dc with ch-2 spaces between them. Join with a sl st to the top of the beginning ch-3. Fasten off or continue in a new color. (6 clusters, 6 ch-2 spaces)
Round 2: Join yarn to any ch-2 corner space. Ch 3 (counts as dc), work 2 more dc in the same space, ch 2, work 3 dc again in the same space (corner made). Ch 1, work [3 dc, ch 2, 3 dc] in the next ch-2 space. Repeat from * four more times. Ch 1, join with sl st to top of beginning ch-3. Fasten off or continue. (12 clusters total)
Round 3: Join yarn to any ch-2 corner space. Ch 3, 2 dc in same space, ch 2, 3 dc in same space (corner). Ch 1, 3 dc in next ch-1 space, ch 1, [3 dc, ch 2, 3 dc] in next ch-2 corner space. Repeat from * four more times, then ch 1, 3 dc in last ch-1 space, ch 1. Join with sl st to top of ch-3. Fasten off. (18 clusters total)
At this point your hexagon should measure roughly 4 to 5 inches across from flat side to flat side, depending on your hook and yarn. You can continue adding rounds in the same pattern — adding one more 3 dc cluster in each side section per round — until you reach the size you want.
Color Choices and Yarn Planning
One of the most joyful parts of a granny hexagon blanket project is the color planning stage. There is really no wrong approach — the blanket is forgiving and welcoming of both careful planning and happy improvisation.
If you love a cohesive, curated look, consider choosing three to five colors that work well together and assigning each one a specific role in the hexagon — for example, one color always for Round 1, another for Round 2, and a third for Round 3. This creates a unified visual rhythm across the whole blanket even if you vary which colors appear together.
If you prefer a more spontaneous, scrappy feel, you can work each hexagon in entirely random colors from your stash. This approach works especially well with a single, consistent “joining” color — a neutral like cream, grey, or black that appears in the final round of every hexagon. That shared border color ties all the motifs together visually even when the interior colors are completely unpredictable.
Gradient blankets are another popular option. You can buy a gradient yarn set designed to blend from one color to another, or you can arrange your hexagons manually by sorting colors from one end of the spectrum to the other before joining, creating a sunrise effect, an ocean fade, or a rainbow across the finished blanket.
Blocking Your Hexagons
Blocking is the step that takes a granny hexagon from “nice” to “beautiful,” and it is particularly important for hexagons because the six sides need to be truly flat and even for the joining process to go smoothly.
Wet blocking is the most straightforward method. Soak your finished hexagons in cool water for about 15 to 20 minutes, gently squeeze out the excess water without wringing or twisting, then pin each hexagon to a blocking mat using rust-proof pins, shaping it so all six sides are equal and the corners are crisp. Allow the hexagons to dry completely — usually overnight — before removing the pins.
Steam blocking works faster and can be done directly on the ironing board or a blocking mat. Hold a steam iron a few inches above each hexagon and let the steam penetrate the fibers. Do not press the iron directly onto the yarn, especially with acrylic fibers that can melt. Shape the hexagon as you steam it and let it cool in position.
For acrylic yarn specifically, some crafters use the “killing” method — pinning the hexagons and pressing with a damp cloth and a hot iron to permanently relax the fibers. This creates a beautifully flat, slightly silky fabric, though it does reduce the elasticity of the yarn somewhat.
Joining Methods for Your Hexagons
How you join your hexagons together matters both for the look of the finished blanket and for how much time you want to spend on assembly. There are several popular methods, each with a different feel.
The flat slip stitch join is worked with the wrong sides held together and a slip stitch worked through both layers across each shared edge. This creates a visible seam on the right side of the blanket, which some crafters love as a design detail and others prefer to minimize.
The flat single crochet join is similar but uses single crochet instead of slip stitch. This creates a slightly raised seam that can be very attractive when worked in a contrasting color — it essentially adds a decorative frame between all the hexagons.
The join as you go method (JAYG) is beloved by crafters who dislike having a large pile of motifs waiting to be assembled. With JAYG, each new hexagon is attached to the previous ones during its final round, meaning you have very little sewing or joining to do at the end. The technique requires a bit of practice to master but becomes very intuitive once you understand the principle.
The mattress stitch or whip stitch are sewn joins worked with a yarn needle. They create an almost invisible seam when done carefully and worked in a matching color, giving the blanket a seamless, flowing look. These work best after blocking when all your hexagons are lying perfectly flat.
Arranging Your Hexagons
Before you start joining, lay all your hexagons out on a flat surface — a bed or the floor works well — and arrange them into your desired pattern. Step back and look at the overall color distribution. Are any colors clustered too close together? Do the transitions between motifs look balanced?
For a blanket that will be roughly rectangular, you will typically alternate between rows of hexagons and offset half-hexagons along the top and bottom edges to create a straight border. Alternatively, you can embrace the organic, scalloped edge that results from using only whole hexagons — some blanket makers love this natural finish as part of the design.
Take a photo of your final arrangement before you start joining. This saves the frustration of forgetting which hexagon went where halfway through assembly.
Adding a Border
Once all your hexagons are joined, a border gives the blanket a finished, intentional look and helps define the edges. The simplest option is a single round of single crochet worked evenly around the entire blanket, followed by a round of reverse single crochet (also called crab stitch) for a neat, textured edge.
For something more decorative, a shell border works beautifully with the hexagonal honeycomb aesthetic. You can also add multiple rounds of granny-style clusters to essentially frame the blanket in the same language as the hexagons themselves.
Whatever border you choose, pay attention to the corners and the concave angles between hexagons along the edge. These areas need a few extra or fewer stitches to lie flat, and a little experimentation in the first round usually sorts out any puckering or pulling.
Tips for Staying Organized on a Large Project
A blanket made from dozens of individual hexagons requires a bit of organizational thinking, especially if you are working on it over several weeks or months.
Keeping a simple tally sheet — whether a paper chart or a notes app on your phone — helps you track how many hexagons you have completed and how many you still need. Some crafters find it motivating to group completed hexagons into sets of ten and photograph their progress regularly.
Weaving in ends as you go, rather than saving them all for the end, transforms what could be a dreaded final task into a manageable part of the workflow. After fastening off each hexagon and before setting it aside, take two minutes to weave in both tails. By the time you have made all your hexagons, you will have nothing left but joining and borders.
Storing hexagons in zip-top bags by color group or completion status keeps your project tidy and makes it easy to grab and go if you want to crochet away from home.
Caring for Your Finished Blanket
The care instructions for your blanket depend entirely on the fiber content of the yarn you used. Most acrylic and acrylic blend yarns are machine washable on a gentle or cool cycle and can be tumble dried on low. Wool and wool blend yarns generally require hand washing or a wool cycle and should be laid flat to dry to prevent stretching.
Regardless of fiber content, washing your finished blanket before gifting or using it for the first time is a nice idea — it relaxes the stitches, evens out any tensions inconsistencies, and gives the whole piece a softer, more cohesive feel.
Why This Project Is Worth Every Stitch
A granny hexagon blanket is not a quick project, and that is part of its value. Each motif is a small, self-contained act of making. Each one you finish is a tiny milestone. Over the course of a project like this — worked in stolen moments, during long evenings, on commutes, or beside a fire — you accumulate not just hexagons but a record of your time and attention. When the blanket is finished and you spread it across a bed or drape it over a couch, what you are looking at is the visible sum of dozens of hours of quiet, purposeful craft.
Few things you can make with a hook and some yarn carry quite that same weight. And few things are quite so satisfying to give, or to keep.
Whether you are making your very first granny hexagon or your twentieth blanket, the process rewards patience and creativity in equal measure. Start with your colors, make a test hexagon, block it, and see how it feels in your hands. Everything else follows naturally from there.
