Grab your hook and your favorite yellow yarn, because this project is as cheerful to make as it is to wear.

Why a Sunflower Granny Square Bandana?

Granny squares have been around for generations, and for good reason. They are portable, beginner-friendly once you get the hang of working in the round, and incredibly versatile. You can use them to make blankets, bags, cardigans, and now — bandanas.

The bandana shape is having a real moment in the crochet community. It is lightweight, quick to finish, and incredibly practical. You can wear it tied at the nape of your neck as a headband, folded into a triangle and tied under the chin in a classic style, or even worn as a small kerchief around a bag handle or ponytail.

Combining these two concepts — the granny square as the central motif and the bandana as the shape — gives you a project that feels cohesive and intentional rather than simply functional. The sunflower is a natural fit because the layered petal rounds of a granny square naturally echo the look of sunflower petals radiating outward from a dark center. With a few smart color choices, you can make a granny square that genuinely looks like it was designed to be a flower rather than a generic geometric motif.

Materials You Will Need

Before diving into the pattern, gather everything you need so your work session goes smoothly.

Yarn: For this project, a lightweight yarn works best — fingering weight or DK weight keeps the bandana soft and comfortable against your hair and forehead without adding bulk. You will need three colors: a dark brown or dark chocolate brown for the center (Color A), a golden yellow for the petal rounds (Color B), and a green for the outer joining rounds and ties (Color C). You can absolutely swap these colors out. A burnt orange center with rust petals and a cream outer border gives a beautiful vintage feel, while a white center with soft lavender petals and a dusty sage border feels more romantic and cottagecore.

Hook: A 3.5mm or 4mm crochet hook works well with DK weight yarn. If you are using fingering weight, drop down to a 3mm hook. Check your yarn’s label for guidance, and always prioritize gauge over a specific hook number.

Other supplies: A yarn needle for weaving in ends, scissors, and a few stitch markers if you like to mark your rounds.

Gauge and Size

Gauge matters here because you want the finished granny square to sit flat and feel comfortable as a bandana center piece. Aim for a square that measures approximately 5 to 6 inches across when finished. If your square is coming out much larger or much smaller, adjust your hook size accordingly.

The finished bandana will have two tie extensions coming off two corners of the square, and it will fit most adult heads comfortably when those ties are between 12 and 16 inches long. The total piece measures roughly 5 to 6 inches at its deepest point (the center square) and can span up to 24 to 30 inches across including the ties.

Understanding the Sunflower Granny Square Construction

This is a five-round granny square designed to mimic a sunflower. The first round forms the center, the second and third rounds add petal layers in yellow, and the fourth round creates a clean transition in green. The fifth round squares off the motif and creates the four corners you will later use to attach the bandana ties.

This is not a traditional corner-chain granny square from the very first round — instead, we build the flower shape first and square it off in the final round. This approach lets the flower feel more organic and circular before the geometric structure comes in.

The Pattern

Abbreviations used:

ch = chain, sl st = slip stitch, sc = single crochet, dc = double crochet, hdc = half double crochet, tr = treble crochet, sp = space, rep = repeat, pm = place marker

Round 1 – The Center (Color A)

Make a magic ring (or chain 4 and join with a slip stitch to form a ring).

Chain 3 (counts as first dc), work 11 more double crochets into the ring. Join with a slip stitch to the top of the beginning chain-3. You will have 12 double crochets total. Pull the magic ring snug.

Fasten off Color A, leaving a short tail. Weave in the end.

Round 2 – Inner Petals (Color B)

Join Color B with a slip stitch to any stitch from Round 1.

Chain 4 (counts as first dc + ch 1). In the same stitch, work 1 more dc. This creates a “V” stitch that forms the base of your first petal.

Join with a slip stitch to the 3rd chain of the beginning chain-4.

Do not fasten off. Continue to Round 3.

Round 3 – Outer Petals (Color B)

Slip stitch into the chain-1 space at the top of the first V-stitch.

Chain 1, then work (sc, hdc, 3 dc, hdc, sc) into each chain-1 space around. These are your petals. Work into every chain-1 space, including the ones between the V-stitches from the previous round — you will have 12 petal spaces total (6 from the V-stitch tops and 6 from the between-stitch spaces).

This creates a full ring of 12 petals that flares outward and gives your sunflower its characteristic bushy, full look.

Join with a slip stitch to the first sc.

Fasten off Color B, leaving a tail to weave in.

Round 4 – Green Transition Round (Color C)

Join Color C with a slip stitch to the sc at the tip of any petal.

This round works behind the petals to create a foundation for squaring off the motif. Chain 4, then work a slip stitch into the sc at the base of the same petal (the stitch on the inner edge of the petal, closest to the center). Work a chain-4 bridge between each petal, slip stitching into the inner base of each one. This creates 12 chain-4 arches sitting behind the petal layer.

Join with a slip stitch at the beginning.

Do not fasten off.

Round 5 – Squaring Off the Motif (Color C)

This round is where the circular flower becomes a proper granny square. You will work four sides with corner chains in between.

Starting in the arch at what will be your top-right corner position:

Corner: Ch 3, work (2 dc, ch 2, 2 dc) into the arch. This is your first corner cluster.

Side: Ch 1, work 2 dc into the next arch, ch 1, work 2 dc into the following arch. This forms one side of the square.

Repeat the corner and two side clusters three more times to complete all four sides and corners.

Join with a slip stitch to the top of the beginning chain-3.

Fasten off Color C. Weave in all remaining ends carefully, using a yarn needle to tuck them through several stitches on the back of the work.

At this point, you have a complete sunflower granny square. Block it lightly by misting with water and pinning to shape if needed, or press gently under a damp cloth.

Adding the Bandana Ties

The ties are what transform the square from a flat motif into a wearable bandana. You will attach two ties — one at the top-right corner and one at the top-left corner of the square. The bottom corner and the left and right corners remain free.

To wear the bandana in the classic triangle style, rotate the square so one corner points downward and two corners point to the sides. The top corner will sit at the crown of your head, and the two side corners become the tie attachment points.

Making the ties:

Join Color C (or Color B for a contrasting tie) with a slip stitch to the chain-2 corner space on the right side of the square.

Chain until the tie reaches your desired length — typically 60 to 70 chains gives you enough length to tie a comfortable bow or knot at the back of your head. Work 1 sc back down each chain to create a firm, non-twisting tie. Fasten off.

Repeat on the left corner.

Alternatively, you can cut lengths of yarn about 3 times the desired tie length, fold them in half, and attach them using a lark’s head knot in the corner spaces, then braid or twist them for a slightly more textured look.

How to Wear Your Sunflower Bandana

The classic way is to fold the square in half diagonally so it forms a triangle, place the longest edge along your hairline, and tie the two ends at the nape of your neck. This gives a retro 1960s look that feels both playful and put-together.

You can also skip the fold and wear the square flat across your forehead like a headband, tying the ends behind your head and letting the colorful square sit as a centerpiece. This works especially well if you are using bold, contrasting colors that you want to show off.

For a boho-inspired look, tie it loosely so the square sits at the side of your head rather than the front, letting one tie drape down like a ribbon. This looks beautiful with loose waves or braids.

The bandana also works as a bag charm — loop one tie through a bag handle, let the square dangle, and tie a small bow to secure it. It adds a handmade, personalized touch to an everyday tote.

Customization Ideas

One of the best things about this pattern is how easily it adapts to different aesthetics. Here are a few variations to consider.

Color variations: Try a pale peach center with coral petals and a warm cream border for a softer, more feminine look. Go monochromatic with three shades of the same color for something sophisticated and modern. Use a variegated yarn for the petal rounds and let the color shifts create natural visual interest without any color changes.

Size variations: Work the square to a larger size by adding extra rounds of double crochet clusters before squaring off. A larger square gives more coverage and works better as a full head scarf rather than a bandana.

Stitch variations: Replace the double crochets in Round 5 with single crochets for a denser, stiffer square that holds its shape better. Use treble crochets for a more open, lacey look that is particularly beautiful with fine cotton yarn.

Edging: Before attaching the ties, work a simple border around all four edges of the square — a round of single crochets in Color A or a picot edge in Color B adds a finished, polished look.

Multiple motifs: Make three or five squares and join them in a row before adding ties. This creates a wider bandana that covers more of the head and has a patchwork quilt aesthetic.

Tips for Success

Working in the round can feel tricky at first if you are used to working flat rows, but a few habits will make the process much smoother.

Always join rounds with a slip stitch unless the pattern specifically instructs otherwise — this keeps your edges clean and prevents the spiral effect that can sneak in when you are working in continuous rounds.

Use stitch markers generously, especially in rounds where you are working between petals or into arches. It is easy to lose your place in a floral pattern where the stitches do not follow a simple grid.

Block your finished square before attaching the ties. Even a quick spray blocking with water and pinning to a foam mat for a few hours makes a dramatic difference in how flat and professional the finished piece looks. Sunflower granny squares have a tendency to want to ruffle at the petal edges, and blocking calms this beautifully.

When weaving in ends, weave in multiple directions — forward a few stitches, then back a few — rather than simply running the tail in one direction. This prevents ends from working loose over time, especially important for something like a bandana that will be put on and taken off regularly.

Yarn Recommendations

Cotton yarn is ideal for a bandana because it breathes well, sits flat, and holds its shape without stretching out of proportion. Lion Brand 24/7 Cotton and Paintbox Cotton DK are both widely available and come in an enormous range of colors, making them perfect for this project. Paintbox in particular has an excellent range of yellows and golds that work beautifully for sunflower petals.

If you prefer a softer feel or want something with a bit of drape, a cotton-acrylic blend like Paintbox Simply DK or Drops Safran gives you the best of both worlds — the structure of cotton with a slightly more forgiving, softer texture.

Avoid wool for this project. While wool is wonderful for many crochet accessories, it tends to be too warm and can feel scratchy against the forehead and hairline. Save your beautiful wool skeins for scarves and hats.

Caring for Your Bandana

Since bandanas sit directly against your skin and hair, they need regular washing. The good news is that cotton crochet is very easy to care for. Hand wash in cool water with a small amount of gentle detergent, squeeze (never wring) the water out, and lay flat to dry. Most cotton yarn handles a gentle machine wash cycle without any problems, but always check your specific yarn’s label first.

Store your finished bandana laid flat or loosely folded rather than balled up — this prevents stretching at the tie attachment points over time.

Final Thoughts

This sunflower granny square crochet bandana is one of those patterns that strikes a perfect balance. It is achievable enough that a confident beginner can complete it in a single afternoon, but it looks polished and intentional enough to wear proudly or gift to someone special. The sunflower motif brings warmth and cheerfulness to any outfit, and the versatility of the bandana shape means it works year-round in different ways.

If you make your own version, take a photo and share it — seeing how other people interpret the color choices and styling is one of the great joys of the crochet community. Swap the yellow for deep rust and you have an autumn harvest vibe. Use pale lavender and soft green and it reads as a spring wildflower. The sunflower granny square is simply a starting point; where you take it from there is entirely your own.

Happy crocheting.
