Sunflower Afghan Crochet Pattern: A Free Blanket Tutorial You’ll Love Making

There is something undeniably cheerful about sunflowers. Their bold yellow petals, dark chocolate centers, and the way they seem to radiate warmth make them one of the most beloved flowers in the world. Now imagine curling up under a blanket covered in them. That is exactly what this sunflower afghan crochet pattern gives you — a cozy, gorgeous blanket that brings the beauty of a sunflower field right into your living room.

Whether you are an experienced crocheter looking for your next satisfying project or an intermediate maker who wants to level up their skills, this pattern is designed with you in mind. The instructions are clear, the stitch combinations are manageable, and the result is absolutely stunning. Plus, there is a full video tutorial linked throughout this post so you can follow along stitch by stitch if written patterns ever feel overwhelming.

Let’s get into everything you need to know to make this beautiful sunflower blanket from start to finish.

Why You’ll Love This Sunflower Afghan Pattern

Before we dive into yarn weights and hook sizes, let’s talk about why this particular pattern is worth your time and your stash.

First, it works up in individual sunflower motifs, which means you can make it portable. Toss a few motifs into your bag and work on them during road trips, lunch breaks, or cozy evenings on the couch. Each motif is a complete, satisfying little project on its own, and watching them pile up is genuinely exciting.

Second, the pattern is highly customizable. You can make a small lap blanket with twelve to sixteen motifs, a full-size throw with twenty-five or more, or even a baby blanket with just nine. Want more of an autumnal feel? Use rust, burnt orange, and deep brown. Prefer something softer for a nursery? Pale yellow and cream work beautifully. The sunflower shape is the constant; the palette is entirely yours.

Third, this blanket photographs incredibly well. If you share your makes on social media or give handmade gifts, this is the kind of piece that gets noticed. The textured center, the layered petals, and the overall warmth of the design make it a showstopper.

Materials You’ll Need

Getting your supplies together before you start will make the whole process smoother. Here is what you will need for a standard throw-sized sunflower afghan measuring approximately 48 by 60 inches.

For yarn, you will want a medium weight (also called worsted weight, or size 4) yarn in three colors. The first is a golden yellow for the outer petals — plan on around 800 yards. The second is a warm sunflower yellow, slightly different in tone if possible, for the inner petals — about 400 yards. The third is a dark chocolate brown or deep mahogany for the flower centers — around 300 yards. For the border and joining, a deep green works beautifully and calls to mind sunflower stems and leaves — plan for about 500 yards.

For hooks, a 5.0mm (size H) crochet hook is ideal for worsted weight yarn, though you should always swatch first and adjust to match gauge.

You will also need a yarn needle for weaving in ends and joining motifs, scissors, and stitch markers if you like using them to keep track of rounds.

Optional but helpful: a blocking board and rust-proof pins. Blocking your finished motifs before joining will give the blanket a much more polished, even appearance.

Understanding the Sunflower Motif

The heart of this pattern is a single sunflower motif. Each finished motif measures approximately 8 inches across, which is a comfortable size — not so small that it takes forever to assemble a blanket, and not so large that the individual flowers lose their charm.

Each motif is worked in the round from the center outward. You begin with the dark brown center, building up texture with popcorn stitches or bobble stitches to mimic the bumpy, seed-filled look of a real sunflower’s face. Then you work outward into the inner ring of petals, followed by the outer ring of longer, overlapping petals. The layers give the flower its dimensional quality and make the finished piece look far more complex than the actual stitch work involved.

Understanding how the layers interact is key to making the motif look right. The petals in the second round are worked behind the petals in the outer round, which creates that natural, slightly overlapping appearance. The video tutorial walks through this technique in real time, which makes it much easier to grasp visually than any written description can fully convey.

The Pattern: Sunflower Afghan Motif

Abbreviations used:
ch = chain, sl st = slip stitch, sc = single crochet, dc = double crochet, hdc = half double crochet, tr = treble crochet, st = stitch, sp = space, BLO = back loop only, bobble = (yarn over, insert hook, pull up loop, yarn over, pull through 2 loops) 5 times in same stitch, then yarn over and pull through all 6 loops on hook.

Gauge: One motif = 8 inches across after blocking.

Center (Brown yarn):

Begin with a magic ring or ch 4 and join with sl st to form a ring.

Round 1: Ch 1, work 8 sc into the ring, join with sl st to first sc. (8 sc)

Round 2: Ch 1, 2 sc in each sc around, join with sl st. (16 sc)

Round 3: Ch 1, work one bobble in each sc around, joining each bobble with a sl st before starting the next. After all 16 bobbles are complete, join with sl st to first bobble. Fasten off and weave in ends.

The bobble round gives the center its bumpy, realistic texture. If you find bobbles tricky, the video tutorial shows a slower demonstration of the technique with plenty of close-up footage.

Inner Petals (Light yellow or secondary yellow yarn):

Join yarn in any stitch of Round 3.

Round 4: Ch 1, sc in same st, ch 3, skip 1 st, (sc in next st, ch 3, skip 1 st) around, join with sl st to first sc. (8 ch-3 spaces)

Round 5: Sl st into first ch-3 sp, ch 1, (sc, hdc, 3 dc, hdc, sc) in each ch-3 sp around, join with sl st to first sc. (8 small petals)

Fasten off and leave a tail for weaving in.

Outer Petals (Golden yellow or primary yellow yarn):

You will be working this round behind the inner petals. To do this, insert your hook from the front of the work through to the back, working into the sc stitches of Round 4 that sit between the inner petal bases.

Round 6: Join golden yellow yarn from the back of the work in any sc of Round 4. Ch 1, sc in same st, ch 5, (sc in next sc of Round 4, ch 5) around, join with sl st to first sc, working behind petals the entire time. (8 ch-5 spaces)

Round 7: Sl st into first ch-5 sp, ch 1, (sc, hdc, 2 dc, tr, 2 dc, hdc, sc) in each ch-5 sp around, join with sl st to first sc. (8 large outer petals)

Fasten off and weave in ends.

Edging Round (Green yarn):

This round squares off the circular motif slightly to prepare it for joining. It transforms the round motif into a shape that can be joined in a grid.

Round 8: Join green yarn at the tip of any outer petal. Ch 3, work 2 dc in same st, ch 2 (corner made), dc in next 4 sts, ch 2 (corner), 3 dc in tip of next petal, ch 2 (corner), dc in next 4 sts, ch 2 (corner), repeat from * around to create 8 corner spaces, join with sl st to top of ch-3. Fasten off.

Note: Because sunflower petals are round and we are working toward a rectangular blanket, the edging round requires a bit of finessing. The video tutorial covers this in detail and shows how to ease the corners to get a flat, neat result. Don’t stress too much about perfection at this stage — blocking does a lot of heavy lifting.

Joining the Motifs

Once you have all of your motifs completed and blocked, it is time to join them together. There are several methods, and the one you choose will affect the final look of the blanket.

The flat slip stitch join is the most invisible — you hold two motifs with wrong sides together and slip stitch through both corner spaces and edge stitches simultaneously. It creates a subtle ridge on the back of the blanket that gives it a little extra structure.

The join-as-you-go method is popular for motif blankets because it eliminates the need for a separate joining step. You work the final edging round of each new motif and join it to the adjacent motif at the corner spaces and edge points as you go. The video tutorial includes a section on join-as-you-go if you prefer this method.

The flat single crochet join creates a slightly more visible seam with a raised ridge on the right side of the work. Some crocheters love this look because it adds a graphic, modern quality to the finished blanket.

For this sunflower afghan, a flat single crochet join in green yarn looks especially beautiful because it mimics a kind of trailing stem between flowers.

Border

Once all motifs are joined, a border brings the whole blanket together and frames it beautifully.

Round 1: Join green yarn at any corner of the assembled blanket. Ch 3, 2 dc in same corner sp, dc evenly across each edge and through joining spaces, working 3 dc in each outer corner, join with sl st. (This round evens out any irregularities from the joining.)

Round 2: Ch 1, sc in each dc around, working 3 sc in each corner, join with sl st.

Round 3: Ch 3, dc in each sc around, working 3 dc in each corner, join with sl st. Fasten off.

For a more decorative border, consider adding a round of shell stitches or a simple picot edge in golden yellow after the green rounds. The contrast is lovely and echoes the petals of the sunflowers themselves.

Video Tutorial

Written patterns are wonderful, but sometimes you just need to see someone’s hands moving through the stitches to fully understand what is happening. That is why this pattern comes paired with a full video tutorial.

The video walks through every stage of the pattern in real time: starting the magic ring, building the bobble center, working the inner and outer petal rounds, completing the edging, and joining the motifs. There are close-up shots for the trickier moments — particularly the behind-the-petals technique for the outer round — and the pace is relaxed enough that you can pause, rewind, and follow along without feeling rushed.

If you are newer to crocheting in the round or have never worked motif-based blankets before, the video is especially helpful for understanding how each round builds on the last and how the finished motif should look at each stage.

Tips for Success

A few notes that will make a real difference in your finished blanket.

Tension matters. If your motifs are curling up or pulling in, your tension is too tight. If they are floppy and loose with visible gaps between stitches, loosen your grip a little. Blocking helps with both issues, but getting your tension close to correct from the start will save you time.

Weave in ends as you go. Each motif has multiple color changes, which means multiple tails to weave in. Doing this as you complete each motif rather than saving them all for the end is strongly recommended. Weaving in hundreds of ends at the end of a project is one of the less joyful parts of crochet.

Block your motifs before joining. Even if you are not usually a blocker, give it a try with this project. Lay your finished motifs on a blocking board, mist them with water, pin them to shape using rust-proof pins, and let them dry completely. The difference in uniformity and neatness is striking.

Count your petals. It sounds obvious, but in the rhythm of working rounds, it is easy to accidentally add or skip a petal. Eight inner petals and eight outer petals are what you are aiming for. If your count is off, it is much easier to fix while the motif is fresh than after you have weaved in all your ends.

Take breaks. This is a large project. Enjoy the process in stages rather than racing to finish. Making five motifs a week means you could have a full throw-sized blanket in five to six weeks, which feels very achievable without burning out.

Yarn Substitutions and Color Ideas

The classic sunflower colorway — golden yellow, warm yellow, and dark brown — is timeless and always stunning. But this pattern is genuinely versatile, and experimenting with color is one of the great joys of making it.

For a bohemian, earthy version, try mustard yellow, terracotta, and deep olive green. For a coastal or farmhouse feel, bleached linen, soft butter yellow, and slate blue look unexpected and beautiful. For a baby blanket, pale lemon, cream, and soft sage are sweet without being saccharine.

The green joining yarn and border can also shift dramatically depending on your palette. Deep forest green, dusty sage, even a rich navy or burgundy can all work beautifully depending on the mood you want the finished blanket to have.

If you are working from your yarn stash, this is a great pattern for using up odds and ends. Each motif uses a relatively small amount of each color, so even partial skeins from past projects can find a home here.

Finishing and Gifting

A sunflower afghan makes an exceptional handmade gift. It is the kind of project that communicates real care and effort — the recipient can see the individual flowers, feel the texture of the centers, notice the layered petals. It does not look like something you could buy at a store.

If you are making this as a gift, consider adding a small handwritten tag that includes a note about the time you put into it, the yarn you used, and care instructions. Most worsted weight acrylic and acrylic blend yarns are machine washable on a gentle cycle, but if you used a natural fiber yarn, hand washing is recommended.

For care, the finished blanket can be stored folded in a linen bag or a cedar chest. Avoid storing in plastic long term, which can trap moisture.

Share Your Finished Sunflower Afghan

One of the best parts of crochet is the community that surrounds it. When you finish your sunflower blanket — or even when you finish your first few motifs — please share photos. Tag your project with sunflower crochet or sunflower afghan on Instagram and Pinterest so other makers can find you and draw inspiration from your color choices and creativity.

Seeing how different crafters interpret the same pattern is endlessly interesting. The same sunflower motif done in a dozen different colorways and yarn textures looks like twelve completely distinct blankets. Your version will be uniquely yours.

If you run into any part of the pattern that feels unclear, drop a question in the YouTube comments or leave a note here. This pattern and its video tutorial are designed to be as beginner-friendly as possible, and getting feedback helps make them better for everyone who comes along after you.

Happy crocheting. May your yarn never tangle and your tension always hold.
