Easy Crochet Granny Stitch Bandana | Triangle Hair Scarf Pattern

There is something endlessly satisfying about a project that looks intricate but takes only a few hours to complete. The granny stitch bandana is exactly that kind of project — a triangle hair scarf that feels like a little celebration every time you put it on. Whether you are a beginner who has just learned your basic stitches or an experienced crocheter looking for a quick and stylish make, this pattern is genuinely one of the most rewarding things you can pull out of your hook bag.

Bandanas and triangle scarves have been having a major fashion moment, and the handmade version blows anything you could buy at a store completely out of the water. You get to choose your colors, your yarn weight, and your size. You get to wear something that nobody else in the world has. And you get the quiet satisfaction of answering “I made it myself” when someone asks where you got that gorgeous scarf tied around your head.

Let’s dig into everything you need to know to make your own crochet granny stitch triangle bandana.

What Is the Granny Stitch?

Before we jump into the pattern itself, it helps to understand why the granny stitch is such a perfect choice for this project. The granny stitch is built from clusters of double crochet stitches grouped together with chain spaces between them. It creates a lacy, airy fabric with just enough structure to hold its shape without becoming stiff or heavy.

For a hair scarf or bandana, this openwork quality is ideal. The fabric sits lightly against your head, breathes in warm weather, and drapes beautifully when you tie it. It also shows off color really well, whether you choose a single solid or decide to stripe across the rows.

The classic granny square uses the same logic as the granny stitch, so if you have ever made a granny square, you already have a solid intuitive understanding of what you are doing here. The bandana version simply works the motif flat in rows, building the triangle shape from the top point down.

Materials You Will Need

One of the best things about this project is how little you need to get started. Here is a straightforward list:

Yarn: Approximately 100 to 150 yards of light worsted weight or DK weight yarn. Cotton yarn works beautifully for this project because it is breathable and easy to wash. Lion Brand 24/7 Cotton, Paintbox Simply DK, and Paintbox Simply Cotton Worsted are all wonderful choices. You can also use a soft acrylic if that is what you have on hand.

Hook: A size 4.0 mm (G hook) or 4.5 mm (7 hook) crochet hook depending on your yarn. If you are using DK weight, go with the 4.0 mm. For light worsted, try the 4.5 mm. Gauge is flexible on this project, so do not stress too much about matching it exactly — a slightly larger or smaller result is still wearable and beautiful.

Notions: A yarn needle for weaving in ends, scissors, and optionally a few stitch markers to keep track of your corners.

Optional: A small amount of coordinating yarn in a second color for the border or the ties.

Gauge and Sizing

This pattern produces a bandana that measures approximately 18 to 20 inches across the longest edge (the top, or hypotenuse of the triangle) and about 9 to 10 inches deep at the center point. This size fits most adult heads comfortably and gives you enough tail on the ties to knot at the back of your neck or on top of your head, depending on how you like to style it.

If you want a larger bandana — one that covers more of your hair and gives you longer ties — simply add more rows and account for extra yardage. Adding six additional rows will give you roughly two more inches of depth and about four more inches across the top edge.

For a child’s version, work fewer rows and you will have a perfectly sized little hair scarf.

GS cluster — granny stitch cluster: 3 double crochets worked into the same space

The fundamental unit of the granny stitch is the cluster of 3 double crochets, and you will always be working into chain spaces rather than into individual stitches. This is the key thing to remember as you work through the pattern. Do not worry about counting individual stitches in each row — focus on the chain spaces and you will always land in the right place.

Pattern Notes

This bandana is worked flat in rows, starting with a small foundation at the top corner and increasing outward on each side to build the triangle. Each row adds one granny stitch cluster on each side, so the triangle grows by one cluster per side per row.

The granny stitch pattern is inherently a multiple, so the increases happen naturally at the corners of the triangle. You will place a corner set — cluster, chain 2, cluster — at the center top on every row, and single clusters separated by chain 1 fill in the body on either side.

The ties are worked as chains at the end of the top edge, or you can add them with a simple crochet chain after the body is complete.

The Pattern

Foundation Chain

Chain 6. Join with a slip stitch to form a ring, or work into the chain as follows:

Row 1: Chain 3 (counts as first dc), work 2 dc into the 4th chain from hook, chain 2, work 3 dc into the same chain space. Turn. You now have 2 clusters with a chain-2 corner space between them.

Row 2

Chain 5 (counts as dc plus chain 2), turn. Work 3 dc into the first chain-2 corner space from the previous row. Chain 2 (this is your new center corner). Work 3 more dc into the same chain-2 space. Chain 2. Work 1 dc into the top of the turning chain from the previous row. Turn.

You now have a small triangle taking shape, with one cluster on each side and a corner in the center top.

Row 3

Chain 3, turn. Work 2 dc into the first chain-2 space (the one just beside your turning chain). Chain 1. Work 3 dc, chain 2, 3 dc into the center corner chain-2 space. Chain 1. Work 3 dc into the last chain-2 space. Work 1 dc into the 3rd chain of the turning chain. Turn.

Row 4

Chain 5, turn. Work 3 dc into the first chain-1 space. Chain 1. Work 3 dc, chain 2, 3 dc into the center corner chain-2 space. Chain 1. Work 3 dc into the last chain-1 space. Chain 2. Work 1 dc into the top of the turning chain. Turn.

Rows 5 Through 18 (or until desired size)

Continue working in the established pattern. The rule is simple:

On every row, you begin and end at the outer edges of the triangle, working a cluster into every chain-1 space you pass. At the center corner chain-2 space, you always work cluster, chain 2, cluster. At the outer edges, you either work a chain-5 turning chain (which counts as your edge dc plus a chain-2 space) or a chain-3 turning chain and then a dc at the end, depending on whether the row ends at the edge or at a chain-2 space.

A good shorthand to remember: if your row ends with a dc into the top of a turning chain, your next row begins with chain 5 and the first cluster goes into the chain-2 space right below. If your row ends with a dc cluster and then a dc into a chain space at the edge, your next row begins with chain 3 and the first cluster goes immediately into the chain-2 edge space.

Work a total of 18 rows for the standard adult size. The triangle will look small and slightly wonky until about row 8 or 9, and then it blooms beautifully into its proper shape. Trust the process.

Finishing the Body

After your final row, fasten off and weave in your ends. At this point you have a clean triangle. Give it a light blocking if you are working in cotton — this means getting the piece damp and pinning it out to its full dimensions on a foam board or towel, then letting it dry completely. Blocking makes an enormous difference in how polished the final piece looks and helps the granny stitch pattern open up evenly.

Adding the Border

A simple border gives the bandana a finished, professional look and helps stabilize the edges.

Join your yarn (same color or a coordinating color) at one of the top corners. Work a row of single crochet all the way around the outside edge of the triangle. When you reach the three points of the triangle — the two top corners and the bottom center point — work 3 sc into the corner stitch to turn cleanly.

For a slightly decorative edge, you can instead work a picot border: single crochet, chain 3, slip stitch back into the first chain to form the picot, then skip one stitch, single crochet, and repeat. This gives a sweet little scalloped edge that elevates the entire piece.

Fasten off and weave in any remaining ends.

Adding the Ties

The ties are what allow you to wear this as a bandana, head scarf, or even a kerchief tied around your neck.

Crochet Chain Ties: Join your yarn at one top corner and chain 60 to 80 stitches (or to your preferred length). Slip stitch back along the chain for a neat, sturdy tie. Fasten off. Repeat on the other top corner.

Single Crochet Ties: For a slightly thicker, more structured tie, work a chain of the desired length and then single crochet back along it. This method creates a tie that holds a knot beautifully and does not stretch out of shape with wear.

Ribbon Ties: If you prefer, simply weave a length of ribbon or twill tape through the stitches at the top edge. This is a great option if you want a silkier look or a bold contrast.

How to Wear Your Crochet Bandana

The triangle scarf is one of the most versatile accessories you can add to your wardrobe. Here are a few ways to style it:

Classic Headband Style: Fold the top edge of the triangle down twice to create a thick band and place it across your forehead. Bring the ties back to the nape of your neck and knot them. This works beautifully with loose hair or a messy bun.

Top Knot Style: Place the center point of the triangle at the back of your neck. Bring the ties up and over your head and tie them in a bow or knot at the top of your head, right in front of your bun.

Hair Wrap Style: Hold the triangle with the long edge along your forehead (like a headband), bring both ties back to the nape of your neck, cross them, bring them forward over your temples, and tie them at the top front of your head. This wraps around more of your hair for a fuller look.

Neck Scarf Style: Fold the triangle in half lengthwise to make a long scarf shape and tie it loosely around your neck for a vintage-inspired kerchief look.

Color Ideas and Yarn Suggestions

The granny stitch bandana is one of those projects that looks completely different depending on your yarn choice. Here are some combinations worth trying:

A single tonal cotton in a deep terracotta or rust shade is timeless and works with almost every skin tone. A variegated or self-striping yarn does all the color work for you and creates a boho, festive look with no effort. Two or three solid colors worked in alternating rows give you a clean, geometric stripe that feels modern and graphic.

For a more elevated, delicate look, try a fine cotton or linen blend in a neutral like oatmeal, cream, or dusty sage. These tones photograph beautifully and dress up any outfit.

For a playful, summery feel, bright saturated colors like cobalt blue, sunshine yellow, or coral orange make the granny stitch texture pop and look absolutely joyful.

Tips for Success

Let the granny stitch breathe. Do not crochet too tightly. The openwork quality of the stitch is part of what makes the bandana so attractive and wearable, and tight tension will close up those lovely chain spaces and make the fabric stiff.

Count your clusters at the end of each row. You should always have one more cluster per side than you had in the previous row. If you ever end up with an extra or a missing cluster, you can usually spot the error by looking at whether there is a chain space you skipped or worked into twice.

Block your finished piece. It takes maybe ten minutes to get the piece damp and pin it out, and it genuinely transforms the look of the finished bandana. Cotton especially responds beautifully to wet blocking.

Weave in your ends as you go if you are changing colors often. This saves you from facing a pile of loose ends at the end of the project.

Variations to Try

Once you have made one bandana, you will likely want to make several. Here are some easy ways to change things up:

Work the body in one color and the border and ties in a contrasting shade. Add a simple tassel or two to the bottom point of the triangle. Try a solid-color body with a border worked in a bright accent. Experiment with a different yarn weight — a fingering weight yarn on a 3.5 mm hook creates a delicate, almost lace-like bandana perfect for dressier occasions.

You can also work this same triangle pattern at a larger size to make a full-size granny stitch shawl or shawlette by simply continuing to add rows until you reach your desired dimensions.

Final Thoughts

The crochet granny stitch bandana is one of those patterns that earns a permanent place in your rotation. It is fast enough to finish in a single evening, versatile enough to wear in a dozen different ways, and beautiful enough that people will genuinely think you spent much more time and effort than you did. It makes a wonderful gift, a satisfying personal project, and a great stash buster for those small amounts of leftover yarn sitting in your collection.

If you make one, take a photo and share it — there is something genuinely lovely about seeing how differently the same pattern looks in different hands and different colors. Every version is its own little piece of art.

Happy crocheting, and enjoy wearing your handmade triangle hair scarf all season long.
