Crochet Pattern & Video | Coastline Sunburst Hexie Blanket × Terracotta Collection by Hue Loco Yarn — Granny Square Throw Afghan, Summer Boho Style

There is something quietly magical about sitting down with a hook and a skein of yarn that genuinely excites you. The color, the texture, the way the light catches each strand as you pull it through a loop — it is one of those small, grounding rituals that turns an ordinary afternoon into something worth remembering. If you have been searching for a crochet project that captures the warmth of a long summer day, the breezy energy of a coastal morning, and the earthy richness of a boho-inspired color story, then the Coastline Sunburst Hexie Blanket is exactly what your hook has been waiting for.

This pattern was designed in collaboration with the Terracotta Collection by Hue Loco Yarn, and from the moment you open that first skein, you will understand why these two things belong together. The palette is sun-drenched and soulful — warm terracottas, dusty mauves, sandstone creams, faded rust, and just enough sage and warm white to keep the whole thing from feeling heavy. It is summer and desert and seaside all at once, and it translates into a hexagon blanket that looks far more complicated than it actually is to make.

Let’s walk through everything you need to know: the yarn, the hook, the pattern construction, tips for joining your hexies, the stitch details, and where to find the full video tutorial that will hold your hand through every single round.

Why Hexagon Blankets Are Worth Every Stitch

Before we dive into the specifics of this pattern, let’s talk about why hexagons have become such a beloved format for crochet blankets in the boho and cottagecore communities over the last several years — because if you are on the fence about tackling a hexie project for the first time, understanding what makes them so special might just tip you over the edge.

Hexagon blankets are essentially a form of modular crochet, meaning you build the blanket one motif at a time rather than working from one edge to the other. This approach has several beautiful advantages. First, it is incredibly portable. Each hexagon is a small, self-contained project, which means you can toss a few skeins and your hook into a tote bag and work on your blanket at the beach, in a coffee shop, or while waiting for an appointment. You are not dragging a growing, increasingly heavy rectangle around with you. Second, it is naturally colorwork-friendly. Switching colors between motifs — or even within a single motif — is intuitive and satisfying, and it is exactly how this Sunburst Hexie pattern uses the Terracotta Collection to such stunning effect. Third, hexagons have an organic, almost botanical quality that lends itself perfectly to bohemian and coastal aesthetics. Arranged together, they create a honeycomb texture that looks handcrafted in the best possible way, because it is.

The Sunburst variation specifically starts from a central round that radiates outward in a star or sunburst formation before transitioning into the classic hexagonal shape. The effect is graphic but soft, structured but organic — and when you lay them all out before joining, they honestly look like something you would hang on a wall.

Meet the Yarn: Hue Loco Terracotta Collection

Hue Loco Yarn has built a devoted following among crocheters and knitters who care deeply about color. Not just any color — curated color, intentional color, the kind of color that makes you feel something when you look at it. The Terracotta Collection is one of their most celebrated releases, and it is easy to see why.

The collection is inspired by the warmth of the natural world: fired clay and sun-bleached stone, the faded red of a terracotta pot left out through summer, the creamy beige of desert sand, the muted green of succulents and sage, and the deep, rich warmth of rust and paprika. These are colors that feel timeless. They are not trending in a way that will make your blanket feel dated in two years. They are the colors of earth and light and warmth, and they will feel just as beautiful in a decade as they do today.

For the Coastline Sunburst Hexie Blanket, the recommended colorway uses five to seven shades from the collection, depending on the size of the blanket you want to make. A throw-sized Afghan typically uses a main color for the sunburst center rounds, two or three secondary shades for the outer hexagon rounds, and one or two accent colors for the join-as-you-go borders. The yarn weight used for this pattern is a DK or light worsted, which gives the finished blanket a lovely drape without being too stiff or too floppy. The fabric has body and structure, but it will still fold beautifully over the back of a sofa or the corner of a bed.

If you cannot access Hue Loco Yarn directly, the pattern notes include suggested substitutions. Look for a smooth, plied yarn in a DK or worsted weight with good stitch definition, since the sunburst rounds rely on visible texture to achieve their effect. A yarn with a slight sheen or a cotton-blend can work beautifully for a summer-weight version of this blanket.

Pattern Overview and What You Will Need

Before you cast on — or rather, before you make your magic ring — here is a quick rundown of everything you need to gather.

Materials: You will need approximately 800 to 1,200 yards of yarn total for a throw-sized blanket, split across your chosen colorways. The range depends on how large you make your hexagons and how many you decide to join. A lap blanket uses fewer motifs; a full throw Afghan uses more. For the Terracotta Collection specifically, the pattern recommends around six skeins across five colors, though purchasing an extra skein of your main color is always wise.

Hook: A 4.0mm or 4.5mm crochet hook works beautifully with DK weight yarn for this pattern. If your gauge tends to run tight, go up to a 5.0mm. The individual hexagon should measure approximately 5 to 6 inches from flat side to flat side when blocked.

Other supplies: You will want a tapestry needle for weaving in ends (and there will be ends — this is the reality of colorwork hexagon crochet, and part of the meditative joy of it), scissors, stitch markers to keep track of rounds, and a blocking mat and pins for the finished motifs. Blocking transforms hexagons from slightly wobbly shapes into crisp, perfectly geometric pieces, and it makes the join-as-you-go process so much easier. Do not skip it.

Skill level: This pattern is written for confident beginners and intermediate crocheters. If you can work in the round, make a magic ring, work chain spaces, and do double crochets and treble crochets comfortably, you have everything you need. The video tutorial walks through every stitch, so even if some of the techniques are new to you, you will not feel lost.

Breaking Down the Sunburst Hexie Pattern

Each hexagon in this blanket is worked in the round from the center outward, and the sunburst effect comes from the way the first few rounds use cluster stitches and chain spaces arranged in a radial formation. Here is a simplified walk-through of the structure.

Round 1 starts with a magic ring and six double crochets. This forms the very center of your sunburst and sets up the six points of your hexagon.

Round 2 introduces the beginning of the sunburst rays. Using chain spaces and either treble crochets or double crochet clusters, you will create six elongated “petals” that radiate outward from the center. This is the round that gives the motif its distinctive starburst quality, and it is deeply satisfying to complete. Color change happens here if you are working a two-color or multi-color center.

Rounds 3 and 4 continue building the sunburst and begin to establish the hexagonal corners. The chain spaces at each corner grow to accommodate the turning angle, and by the end of round 4 you can start to clearly see the hexagon shape emerging from the starburst center.

Rounds 5 and 6 complete the hexagon body and add the final border round, which is worked in a single color and will become the joining edge when you connect your motifs. This outer round uses a simple shell stitch or a picot-chain border depending on your preference — both options are included in the pattern.

The full written pattern includes stitch counts for every round, notes on color placement for the Terracotta Collection specifically, and a chart diagram for visual learners. It is available as a downloadable PDF in the link below the video tutorial.

Join-As-You-Go: The Method That Makes It All Come Together

One of the most satisfying things about this pattern is that it uses a join-as-you-go technique for assembling the hexagons, which means you are essentially connecting them as you crochet the final round of each new motif rather than sewing them together afterward. This is a game-changer for anyone who has ever finished a pile of beautiful motifs and then stared at them for three weeks because the thought of seaming them all together felt overwhelming.

The join-as-you-go method for hexagons works by replacing some of the chain stitches in the outer border round with slip stitches into the corresponding stitch on the adjacent motif. The connection is invisible and secure, and the joined seam becomes part of the overall texture of the blanket. When you are using the Terracotta Collection and each hexagon has slightly different color placement, the seams actually create a beautiful secondary pattern where the colors interact along the joining edges.

For your first blanket, it helps to lay out all your finished and blocked hexagons before you begin joining, arranging them the way you want them to appear in the final piece. Take a photo of your layout so you can reference it as you work. Then join from the center of the blanket outward, or from one corner across, depending on what feels intuitive to you.

Blocking: The Step That Takes Your Hexies from Good to Great

If you have crocheted motifs before and skipped blocking, this is your sign to try it at least once and see how dramatically it changes the finished result. Blocking is the process of wetting your finished hexagons (or using a steam iron with a cloth barrier), shaping them into perfect hexagons, and pinning them flat until they dry. It evens out tension inconsistencies, opens up the stitch pattern so you can see all the beautiful textural detail, and — crucially for hexagons — gives you crisp, flat corners that join perfectly.

Blocking hexagons is actually very meditative. You pin one side, count to the next corner, pin the next side, and work your way around. When you have a tray of thirty blocked hexagons all laid out in their perfect geometric shapes, each one in a different combination of those warm terracotta tones, it is genuinely one of the most beautiful sights in the crochet world.

The Boho Coastal Aesthetic: Styling Your Finished Blanket

Once your Coastline Sunburst Hexie Blanket is complete, the fun of styling it begins. The Terracotta Collection gives this blanket a chameleon quality — it can live in multiple different home aesthetics depending on how you use it.

Draped over the back of a cream or natural linen sofa, it reads as pure coastal boho. The warm terracottas against the creamy neutrals feel beachy and sun-faded in the most beautiful way. Folded at the foot of a bed with white linen bedding and some rattan or woven accessories nearby, it becomes part of a desert-inspired, earthy bedroom moment. Spread out on a picnic blanket at the beach or the park, it photographs like something out of a lifestyle magazine, and it is genuinely functional because it is large enough to curl up under, soft enough to use as a wrap, and lightweight enough to carry around all summer.

This is the kind of make that does not disappear into a drawer. It lives on display, because it is genuinely too beautiful to fold away.

The Video Tutorial: Watch and Crochet Along

For those of us who learn best by watching, the full video tutorial for the Coastline Sunburst Hexie Blanket is available on the Hue Loco Yarn YouTube channel and linked directly from the pattern page. The video breaks down the pattern into three main sections: working the sunburst center rounds, completing the hexagon body and border, and joining the motifs using the join-as-you-go technique.

The tutorial is filmed in close-up with clear lighting so you can see every stitch as it forms. The instructor works through the pattern in real time, pointing out common tension mistakes, explaining when and how to change colors cleanly, and demonstrating the blocking process with a tray of motifs at different stages. Even if you have been crocheting for years, a video like this one has a way of offering at least one small tip or technique refinement that improves your finished result.

The video is split into timestamps so you can jump directly to the section you need, which is helpful once you are partway through the project and just need a quick refresher on the join-as-you-go method before you start your next motif.

Community, Creativity, and the Hue Loco World

Part of what makes working with a yarn from a collection like this one so special is the community that builds up around it. When you make the Coastline Sunburst Hexie Blanket in the Terracotta Collection, you are joining a whole group of makers around the world who are working on the same palette, solving the same little creative puzzles, and sharing their results. Hue Loco has an active presence on social media and a growing community of crocheters and knitters who tag their makes and share their color placement decisions, their blocking setups, their finished blanket photos.

If you make this blanket, share it. Use the hashtag, tag the designer, post your hexagon layout before you start joining. You will get encouragement, you might spark someone else’s creativity, and you will become part of the living, ongoing story of this pattern — which is one of the most genuinely lovely things about the modern handmade community.

Final Thoughts: Why This Is the Summer Crochet Project

The Coastline Sunburst Hexie Blanket by Hue Loco Yarn is not just a beautiful project. It is an approachable one. It is one of those patterns that teaches you techniques as you go — the magic ring, working in the round, color changes, join-as-you-go, blocking — in a context where every finished motif is a small victory that you can hold in your hand and admire before moving on to the next. There is no long, uncertain middle stretch where you are staring at an endless expanse of the same stitch in the same color wondering when it will be done. Every hexagon is its own little beginning and ending, its own complete little world.

And the Terracotta Collection makes every single one of those worlds feel warm, considered, and beautiful.

If this is the summer you finally try hexagon crochet, or if you are a seasoned hexie maker looking for a palette that will make you fall in love with the format all over again, this is your pattern. Get the yarn, download the PDF, queue up the video, and make yourself a blanket that looks as good as the season feels.
