Sunflower Granny Square Crochet Crop Top | Free Step By Step Pattern + Tutorial

There is something undeniably magical about sunflowers. They follow the light, they stand tall, and they carry that unmistakable golden warmth that makes everything around them feel more alive. So when you combine the timeless charm of the granny square with the boldness of a sunflower motif and the breezy appeal of a crop top silhouette, you end up with a garment that is nothing short of showstopping. This free pattern is designed for crocheters who are ready to move beyond basic squares and create something truly wearable, beautiful, and uniquely theirs.

Whether you are shopping for a festival outfit, a beach cover-up, a summer layering piece, or just a new project that will actually get worn, this sunflower granny square crochet crop top is exactly what your hook has been waiting for. I am going to walk you through every single step, from materials to finishing touches, so that even if you have never made a garment before, you can follow along with confidence.

What Makes This Pattern Special

Granny squares have been around for generations, and for good reason. They are portable, they work up quickly, and they create a graphic, geometric texture that flatters nearly every body type when assembled thoughtfully. This pattern takes the classic granny square construction and layers in a sunflower motif at the center of each square, giving you a piece that feels both vintage and completely fresh.

The crop top silhouette makes this a highly versatile piece. You can wear it over a bikini top at the beach, over a fitted tank for a festival look, or over a simple bandeau for a casual summer day. The open, lacy nature of granny square construction means the top stays light and breathable even in peak summer heat.

This pattern is written for a range of sizes and uses a simple join-as-you-go technique that keeps the finishing work minimal and satisfying. No complicated seaming, no fussy blocking required — just clean, connected squares assembled into a wearable piece of fiber art.

Materials You Will Need

Before you begin, gather everything on this list so you can work through the pattern without interruption.

Yarn: You will need a lightweight cotton or cotton-blend yarn in three colors — one for the sunflower center (dark brown or deep burgundy works beautifully), one for the petals (a warm golden yellow or butter yellow), and one for the background and joining rounds (white, cream, sage green, or any neutral that complements your flower colors). For a finished top, you should have approximately 200 to 250 yards of the petal color, 100 yards of the center color, and 400 to 500 yards of the background color depending on your size.

Hook: A size 4mm (US G/6) crochet hook works well for most DK or light worsted cotton yarns. If you tend to crochet tightly, size up to a 4.5mm hook to keep your squares relaxed and slightly open.

Other supplies: A tapestry needle for weaving in ends, scissors, stitch markers, and a measuring tape. Optional but helpful: a piece of blocking foam or mat and rust-proof pins if you want perfectly uniform squares before joining.

Gauge and Sizing

Gauge matters more for garments than for almost any other crochet project, so please take the time to make a swatch before diving into your full squares.

With the recommended yarn and a 4mm hook, your finished granny square should measure approximately 5 inches by 5 inches after a gentle blocking or pressing with a damp cloth.

This crop top is designed using a grid of squares assembled as follows:

For a small (fits approximately 32 to 34 inch bust): 8 squares total, 4 squares wide and 2 squares tall for the body panel, worn as a tube with a tie or drawstring at the top edge.

For a medium (fits approximately 35 to 37 inch bust): 10 squares total, 5 squares wide and 2 squares tall.

For a large (fits approximately 38 to 42 inch bust): 12 squares total, 6 squares wide and 2 squares tall.

For an extra large or extended plus (fits approximately 43 to 48 inch bust): 14 squares total, 7 squares wide and 2 squares tall.

The crop top sits just below the bust line and is designed with a relaxed, slightly loose fit. If you prefer a more fitted look, make one size down from your usual. If you prefer a longer crop that covers the midriff, simply make your grid 3 squares tall instead of 2, adding an extra row of squares.

Understanding the Sunflower Granny Square

The sunflower granny square in this pattern is worked in three main parts: the center button, the petal ring, and the granny square background. You build each section in rounds, working the center first and then building outward to the full square. This approach means every square is self-contained and portable — perfect for working on the go.

A quick note on abbreviations used throughout this pattern: ch means chain, sl st means slip stitch, sc means single crochet, dc means double crochet, hdc means half double crochet, sp means space, and yo means yarn over. All instructions are written in US crochet terminology.

The Sunflower Granny Square Pattern

Round 1 — The Sunflower Center (dark brown or deep burgundy yarn)

Make a magic ring. Chain 3 (this counts as your first double crochet). Work 11 more double crochets into the ring — 12 double crochets total. Slip stitch to the top of the beginning chain-3 to join. Fasten off and weave in the end. Pull the tail of the magic ring snug so the center closes tightly into a small, firm button shape.

Round 2 — The Petals (yellow yarn)

Join your yellow yarn to any stitch from Round 1 with a slip stitch. To make each petal, chain 4, then work 2 triple crochets into the same stitch (or work 3 double crochets if you prefer slightly shorter petals — both look lovely), then chain 4 and slip stitch into the same stitch to close the petal. Slip stitch into the next stitch of Round 1. Repeat this process around all 12 stitches of Round 1, making one petal in each stitch. You will have 12 petals total. Slip stitch to the base of the first petal to close the round. Fasten off your yellow yarn and weave in the end.

Round 3 — The Granny Square Foundation (background/neutral yarn)

Join your background color yarn to the tip of any petal with a slip stitch. Chain 3 (counts as dc), work 2 more dc into the same petal tip. Chain 2. Work 3 dc into the next petal tip. Continue working 3 dc clusters separated by chain-2 spaces into each petal tip around, until you have worked 12 clusters total with 12 chain-2 spaces. Slip stitch to the top of the beginning chain-3 to join. This creates the circular base from which you will build your square corners.

Round 4 — Creating the Square Shape (background/neutral yarn)

This is where your circle becomes a square. You will designate 4 of your 12 spaces as corners and the rest as side spaces.

Chain 3 (counts as dc). Work 2 dc in the same space. Work a corner by chaining 2, then working 3 dc into the same space again. This creates your first corner cluster. Chain 1. Work 3 dc into the next chain-2 space. Chain 1. Work 3 dc plus chain-2 plus 3 dc into the next space for your second corner. Continue in this way — 3 dc, chain 1, 3 dc cluster, chain 1, then a corner (3 dc, chain 2, 3 dc) — spacing your corners evenly so you have 4 corner points and 2 standard cluster groups between each corner. Slip stitch to the top of the beginning chain-3 to join. You should now have a recognizable square with 4 corners.

Round 5 — Final Square Round (background/neutral yarn)

Chain 3 (counts as dc). Work along each side by doing 3 dc into each chain-1 space, and at each corner chain-2 space, work 3 dc, chain 2, 3 dc. This will square up the edges cleanly and give each square a finished, uniform look. Slip stitch to join. Fasten off and weave in all ends.

Your finished square should be approximately 5 inches square. Lightly press or wet block for best results.

Joining Your Squares

Once you have made all of your squares, it is time to assemble them into the body of your top. The flat slip stitch join is my preferred method for this project because it creates a slightly raised ridge that adds to the visual texture and gives the joins an intentional, decorative quality.

Lay out your squares in your chosen grid formation, right sides facing upward, to confirm the arrangement before you begin. You want the sunflowers all oriented the same direction or, for a more playful look, slightly varied in rotation.

Hold two squares with wrong sides together. Using your background yarn and hook, insert your hook through the corresponding corner chain spaces of both squares, pull up a loop, and slip stitch along the edge, inserting your hook through the chain spaces and stitches of both layers as you go. When you reach the end of the seam, fasten off. Repeat for each pair of squares until all horizontal joins are complete, then join the vertical seams in the same way. Finally, join the two short ends of your assembled panel together to form a tube.

Finishing the Top — Neckline and Hem

Your assembled tube is the body of the crop top, but you will want to finish the top and bottom edges to give the garment a polished look and help it hold its shape.

Bottom Hem:

Join your background yarn to any stitch at the bottom edge of the tube. Work one round of single crochet around the entire bottom edge, inserting your hook into the edge of each square and through the join seams as you go. Work a slip stitch join to close the round. Chain 1 and work one more round of reverse single crochet (also called the crab stitch — worked right to left instead of left to right) for a neat, cord-like border. Fasten off and weave in ends.

Top Neckline with Tie Option:

The top edge of the tube becomes the neckline. Join your background yarn and work one round of single crochet around the top edge. On the next round, work a chain-2 space, skip 2 stitches, dc into the next stitch — continue in this way around the entire top edge to create an eyelet row. Work one final round of single crochet to frame the eyelets.

Cut a length of yarn approximately 1.5 yards long and braid or twist it into a simple cord, or use a complementary ribbon. Thread this through the eyelet row at the neckline. When worn, you can cinch the neckline to your desired fit and tie the cord in a bow at the front or back. This adjustable tie feature makes the pattern work for a wide range of sizes and preferences.

Styling Your Sunflower Crop Top

This top truly shines when you lean into its boho, sun-soaked energy. Pair it with high-waisted denim shorts and flat sandals for a classic summer festival look. Layer it over a simple white ribbed tank and tuck into a flowy midi skirt for something a little more polished. Worn over a bikini at the beach or poolside, it works perfectly as a cover-up that actually keeps the sun off your skin while still feeling light and airy.

In terms of color, the classic yellow-on-white sunflower combination is always stunning, but do not be afraid to experiment. A rust and terracotta version with a cream background has a beautiful autumnal warmth. A lavender and sage palette gives the sunflower motif an unexpectedly dreamy, whimsical quality. Deep gold petals against a black background create a dramatic, graphic look that feels just as much at home at an evening concert as it does at the farmers market.

Tips for Success

Cotton yarn can be less forgiving than wool when it comes to gauge consistency, so if you find your squares coming out uneven, try slowing down your tension or switching to a slightly larger hook. Blocking your squares before assembly makes an enormous difference in the final appearance of the top — even a simple pressing with a damp cloth can transform slightly puckered, uneven squares into crisp, uniform tiles.

If you are making this top as a gift and are not sure of the recipient’s size, err on the side of larger. The tie neckline gives the top a great deal of adjustability, and the relaxed silhouette looks intentional at a range of fits.

For beginners who are tackling their first garment, I want to say this clearly: you can do this. The sunflower granny square is slightly more detailed than a traditional four-round granny, but the construction is logical and the steps build on each other in a satisfying way. Take it one square at a time. Celebrate each one as a small finished object. By the time you reach your final square and start joining, you will have the pattern memorized and the process will feel completely natural.

Variations and Creative Extensions

Once you have made this top, you will find that the sunflower granny square is endlessly adaptable. Use the same squares to make a matching beach bag by assembling a 3×4 grid, seaming three sides, and adding a chain or braided handle. Make a coordinating headband using just two squares joined side by side and fitted with an elastic band at the back. Scale the pattern up with a bulkier yarn and larger hook and you have a stunning wall hanging for a bedroom or sunroom.

You can also extend the crop top pattern into a full camisole or mini dress simply by increasing the number of square rows. A three-row version creates a flattering camisole that hits at the natural waist. Four rows gives you a mini dress that works beautifully over shorts or a swimsuit.

A Note on Sustainability

Cotton yarn made from organic or recycled fibers is a wonderful choice for this project, and because the crop top is relatively small, even a premium sustainable yarn brand stays within a reasonable budget. Choosing a high-quality cotton yarn also means your finished top will last for many seasons and hold its color and shape wash after wash.

This sunflower granny square crochet crop top is one of those projects that stays with you long after it is finished. There is something deeply satisfying about wearing something you made yourself, particularly something as graphic and eye-catching as this. If you make your own version, I would love to see it — tag your finished tops and share your color combinations. The crochet community thrives on inspiration, and your sunflower top just might inspire someone else to pick up a hook for the very first time.

Happy crocheting, and may every stitch bring you a little closer to something beautiful.
