Willow Granny Square – Free Crochet Pattern

There is something timeless about a granny square. Whether you learned to crochet from a grandmother who kept a basket of yarn beside her favorite chair, or you discovered the craft through a late-night YouTube spiral, the granny square has a way of feeling both nostalgic and completely fresh. The Willow Granny Square is one of those patterns that takes everything you already love about the classic design and adds a layer of elegance that makes it feel brand new. With its delicate petal-like clusters and open, airy structure, the Willow square is equally at home on a cozy blanket, a market bag, or a set of throw pillows.

This free crochet pattern is written for beginners who are comfortable with basic stitches but want to try something a little more refined. If you have made a traditional granny square before, you will find the Willow version approachable and satisfying. If this is your first granny square ever, welcome — you have chosen a beautiful place to start.

What Makes the Willow Granny Square Different

Classic granny squares are built around clusters of three double crochets separated by chain spaces. The Willow Granny Square follows a similar philosophy but introduces a petal cluster stitch that gives each round a softer, more floral appearance. Instead of sharp corners punctuated by double crochet groups, the Willow square seems to bloom outward from its center, with gentle curves that evoke the way willow branches drape toward the ground.

The name itself comes from that flowing quality. When you arrange several finished squares together — whether in a lap blanket or a wall hanging — the overall effect resembles the layered, overlapping leaves of a weeping willow tree. It is a pattern that rewards you as you go, looking more impressive with every round you complete.

Materials You Will Need

Before casting on, gather everything you need so your session flows without interruption.

Yarn: Worsted weight yarn works beautifully for this pattern and gives you a finished square of approximately 6 inches when blocked. You can use any fiber you love. Cotton is wonderful for warm-weather projects like bags and dishcloths. Acrylic is an excellent choice for washable baby blankets. Wool or wool blends give you a gorgeous drape and the most satisfying blocking results. For a single square you will use roughly 30 to 40 yards of each color you choose to incorporate.

Hook: A US size J (6mm) crochet hook is recommended for worsted weight yarn. If you tend to crochet tightly, go up to a K (6.5mm) hook. If you crochet loosely, try an I (5.5mm). Your gauge does not need to be precise for most projects that use this square, but consistency across all your squares is important if you are making a blanket.

Other supplies: A yarn needle for weaving in ends, scissors, and locking stitch markers (optional but helpful for beginners marking corner spaces).

Abbreviations and Stitches Used

This pattern is written using US crochet terminology.

ch — chain
sl st — slip stitch
sc — single crochet
dc — double crochet
tr — treble crochet
sp — space
ch-sp — chain space
beg — beginning
rep — repeat
pm — place marker

Petal Cluster (PC): (dc, ch 1, dc, ch 1, dc) all in the same stitch or space. This three-double-crochet cluster with chain-one separators forms the signature petal of the Willow square.

Corner Shell: (2 dc, ch 2, 2 dc) all in the same corner chain-two space.

Pattern Notes

Read through the entire pattern before you begin. This is a habit worth developing early in your crochet life — it prevents surprises mid-round and gives you a clear mental picture of where you are headed.

Each round is joined with a slip stitch unless otherwise noted. You may crochet in a continuous spiral if you prefer, but the joined method gives cleaner, more defined color changes.

To change colors cleanly, make your last slip stitch join of the old round using the new color. Cut the old yarn and pull the tail through, then begin your new round with the new color. Weave in ends as you go or save them all for the end — both approaches work.

This pattern is shown as a four-round square, which produces a finished size of approximately 5.5 to 6 inches before blocking and 6 to 6.5 inches after blocking with worsted weight yarn. You can add additional rounds using the Round 4 pattern to make a larger square.

The Willow Granny Square Pattern

Round 1 — The Center (Color A)

Begin with a magic ring or chain 4 and join to form a ring with a slip stitch.

Ch 3 (counts as first dc throughout), dc in ring, ch 1, (2 dc, ch 1) 7 times in ring — you will have 8 groups of 2 double crochets separated by chain-one spaces.

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

Fasten off Color A or continue with Color B.

Stitch count: 16 dc, 8 ch-1 spaces.

This tight, tidy center ring is the foundation for everything that follows. Take a moment to pull the magic ring closed firmly so there is no hole in the middle of your square.

Round 2 — The First Petal Round (Color B)

Join Color B with a slip stitch in any ch-1 space.

Ch 4 (counts as dc + ch 1), dc in same sp, ch 1 — this begins your first petal cluster.

In the next ch-1 sp, work (dc, ch 1, dc, ch 1, dc), ch 1. Rep from around, working a Petal Cluster in each of the remaining 7 ch-1 spaces.

Join with a slip stitch to the third ch of beginning ch-4.

Fasten off Color B.

Stitch count: 8 Petal Clusters (24 dc total), 24 ch-1 spaces.

After this round your center will have taken on a distinctly floral shape. The petal clusters fan outward like little petals from the ring, which is exactly the effect you are after.

Round 3 — Building the Square Shape (Color C)

This is the round where your circle transforms into a square. The corners are established here.

Join Color C with a slip stitch in any ch-1 space between two Petal Clusters (the ch-1 spaces that sit between clusters, not within them).

Ch 3 (counts as dc), dc in same sp, ch 2, 2 dc in same sp — this forms your first corner shell.

Ch 1, skip the next ch-1 sp, sc in the center dc of the next Petal Cluster, ch 1, skip the next ch-1 sp, (2 dc, ch 2, 2 dc) in the next ch-1 sp between clusters (corner made). Rep from 3 times more.

Ch 1, skip next ch-1 sp, sc in center dc of next Petal Cluster, ch 1.

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

Fasten off Color C.

Stitch count: 4 corner shells (16 dc), 4 sc, 8 ch-1 spaces, 4 ch-2 corner spaces.

At this point you may want to place stitch markers in your four corner chain-two spaces. These markers make the next round much easier to navigate, especially if you are working through a new pattern for the first time.

Round 4 — The Outer Border (Color D or Color A for a matching frame)

This round adds a full outer border and reinforces the square’s shape. It introduces a second set of petal-style clusters along the sides.

Join yarn with a slip stitch in any corner ch-2 sp.

Ch 3, (dc, ch 1, dc, ch 1, dc) in same corner sp — this is a full Petal Cluster in the corner, ch 1, dc in same sp again — you are making an expanded corner with a total of 5 dc fanning out: (dc, ch 1, dc, ch 1, dc, ch 1, dc, ch 1, dc) — actually work a Corner Petal: (2 dc, ch 2, 2 dc) in the corner sp, then continue around the side.

Let me simplify the corner for clarity:

In each corner ch-2 sp: (2 dc, ch 1, 2 dc, ch 2, 2 dc, ch 1, 2 dc) — this elongated corner shell creates a lovely mitered look. Alternatively, for a cleaner corner, work the standard (2 dc, ch 2, 2 dc) and build the side stitches separately as follows:

Simplified Round 4:

Join in any corner ch-2 sp.

Ch 3, (dc, ch 2, 2 dc) in same sp — corner made.

Ch 1, dc in next ch-1 sp, ch 1, (dc, ch 1, dc) in the sc from previous round (this creates a mini-petal on each side), ch 1, dc in next ch-1 sp, ch 1, (2 dc, ch 2, 2 dc) in next corner ch-2 sp. Rep from around.

Ch 1, dc in next ch-1 sp, ch 1, (dc, ch 1, dc) in sc, ch 1, dc in next ch-1 sp, ch 1.

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

Fasten off. Weave in all ends.

Finished square measurements: Approximately 6 inches unblocked, 6.5 inches blocked.

Blocking Your Willow Granny Squares

Blocking is the step that transforms a crochet project from looking handmade to looking professionally crafted. It opens up the stitch definition, evens out any tension inconsistencies, and sets the size of each square so they all match when you go to join them.

For cotton or acrylic yarn, wet blocking works well. Submerge your finished squares in cool water, gently squeeze out the excess (never wring or twist), and lay them flat on a blocking mat. Use rust-proof pins to pin each square into its proper shape, measuring to ensure all four sides are equal. Let them dry completely before unpinning.

For wool, you can use the same wet blocking method or steam blocking. Steam blocking is faster — hold a steam iron a few inches above the surface of the damp square and allow the steam to penetrate the stitches without pressing directly on the fabric. The heat and moisture together relax the fibers into position beautifully.

Acrylic-only yarns do not respond to water blocking the same way natural fibers do. You can use a technique called “killing” acrylic — placing a damp cloth over the squares and pressing with an iron — but be careful, as too much heat will melt the fibers. Many crocheters skip blocking acrylic entirely and simply pin the squares to shape while assembling them.

Color Combinations to Try

One of the greatest joys of the granny square format is how completely customizable it is through color choice alone. The same Willow pattern can feel rustic, modern, boho, or classic depending entirely on your palette.

For a bohemian aesthetic, try warm terracottas, dusty rose, sage green, and cream. The earthy tones complement the floral structure of the petal clusters beautifully.

For a modern minimalist look, stick to two colors only — a deep charcoal for Rounds 1 and 3 and a warm white for Rounds 2 and 4. The restraint makes the stitch structure the focal point.

For a baby blanket, soft pastels in mint, lavender, butter yellow, and blush are perennially sweet. Using the same border color across all squares helps unify a scrappy multi-color blanket.

For a maximalist statement piece, pull every color from your stash and use a different palette for each square. Join them with a single neutral color — black, cream, or grey — to bring the chaos into harmony.

Joining Willow Granny Squares

Once you have made enough squares for your project, you will need to join them together. There are several methods, and each gives a different effect.

The flat slip stitch join is the most invisible of the joining methods. Hold two squares with right sides facing together and slip stitch through the back loops of both edges. This creates a tiny seam on the wrong side and a nearly seamless appearance on the front.

The flat single crochet join is slightly more visible and creates a small ridge on the wrong side. It is sturdy and reliable for blankets that will see a lot of use.

The join as you go method (JAYG) is beloved by many crocheters because it eliminates a separate joining step entirely. On the final round of each new square, you join it to its neighbors in the corner spaces and along the sides as you work. This keeps your project tidy and manageable throughout.

The chain join creates small decorative chains between squares, preserving an open, lacy look that suits the Willow square’s airy design particularly well. Work a sl st through the corner sp of the first square, chain 3, sl st through the corner sp of the second square — this creates a small bridge between them.

Project Ideas Using the Willow Granny Square

The versatility of this square is one of its best qualities. Once you have mastered the four-round version, you can scale up or down based on the project you have in mind.

A lap blanket made from 35 squares in a 5×7 layout works up quickly on weeknights. Choose a color story of three to five complementary shades and mix them randomly for a vibrant, cheerful effect.

A full throw blanket using 63 squares in a 7×9 layout gives you something substantial enough to curl under on a cold night. Border the finished blanket with two or three rounds of single crochet and a final round of reverse single crochet for a polished edge.

A tote bag made from 12 squares — six for the front panel and six for the back panel — joined at the sides and bottom, with a simple crocheted strap, is one of the most satisfying quick makes. Line it with cotton fabric for extra durability.

A table runner made from 8 to 12 squares in a single row is a quick weekend project and makes a beautiful handmade gift.

Pillow covers using four large squares (made larger by adding extra rounds) fit nicely over a 20-inch pillow form and look lovely on a sofa or bed.

Tips for Success

Tension is the most common challenge for beginner and intermediate crocheters alike. If your squares are curling up at the edges, your tension is too tight — try going up a hook size. If they are floppy and misshapen, go down a size.

Always make a test square before committing to a large project. A test square lets you check your sizing, assess how your chosen yarn behaves with this stitch pattern, and confirm that you understand the pattern fully before you have thirty squares to redo.

Weave in ends as you go rather than saving them all for the end. A finished blanket with hundreds of ends waiting to be woven in can be deeply discouraging. Handling each end when it is fresh keeps the finish line in sight.

When counting your chains at the beginning of a round, count carefully. A missed chain at the beginning of a round is one of the most common pattern errors and can throw off your stitch count for the entire round.

If you are making a large project over several weeks, keep a note — even just a sticky note on your yarn bag — about which color goes in which round. Memory is less reliable than we like to think, and consistency across all your squares will make assembly much smoother.

Final Thoughts

The Willow Granny Square is exactly the kind of pattern that reminds you why you fell in love with crochet. It is simple enough to work through without constant pattern-checking, yet detailed enough to hold your interest round after round. The petal clusters give it a handcrafted quality that looks far more complex than it actually is, which means your finished project will receive admiration far beyond the time it took you to make it.

Whether you are working toward a full blanket, a quick gift, or simply the pleasure of making something beautiful with your hands, this pattern rewards every minute you put into it. Grab your favorite yarn, settle into your best chair, and let the
