. The best part? You can make one yourself for the cost of a skein of yarn, and it’ll look just as good (if not better) than the $78 ones in stores.

Why Granny Square Bucket Hats Are So Popular

Surprisingly quick: Many patterns work up in under 3 hours .
Fits everyone: With simple adjustments, you can make these for babies, kids, or adults .

What You’ll Need

Table

Supply	Details
Yarn	Worsted-weight cotton (size 4). Cotton breathes and holds shape. About 80–100g total .
Hook	5.5mm (US I-9) for granny stitch in the round , or 4.0mm (US G-6) for patchwork style .
Yarn needle	For weaving in ends and sewing squares together.
Scissors	Essential.
Stitch markers	Optional but helpful for keeping track of rounds.

Pro tip: Cotton yarn is non-negotiable for summer hats. Acrylic gets hot, stretches out, and loses its shape in the sun. Cotton stays crisp and cool

Step-by-Step Granny Square Bucket Hat

This is the classic look you see in stores — actual granny squares sewn together, with a brim crocheted around the bottom. The Yarnspirations pattern (also available as a free download) uses this method.

Step 1: Make the Granny Squares

You’ll need 5 or 6 granny squares, depending on head size. Each square should measure about 4–5 inches.

Classic Granny Square Pattern:

Round 1: Chain 4, slip stitch to form a ring. Chain 3 (counts as dc), 2 dc in ring, ch 2, 3 dc in ring — repeat 2 more times. Ch 2, slip stitch to top of ch-3. (4 clusters, 4 ch-2 corners)

Round 2: Slip stitch into the next 2 stitches and into the corner space. Ch 3, 2 dc in same corner, ch 2, 3 dc in same corner (first corner made). Ch 1, [3 dc, ch 2, 3 dc] in next corner — repeat around. Ch 1, slip stitch to top of ch-3.

Round 3+: Continue working [3 dc, ch 2, 3 dc] in each corner and 3 dc in each side space, with ch-1 between groups. Add rounds until your square is the right size.

Make all squares the same size. Use one color or change colors every round for a rainbow effect.

Step 2: Sew Squares Together

Arrange your squares in a circle — this forms the “band” of the hat. Sew them together using whip stitch or mattress stitch. Make sure the total circumference matches the head size you’re aiming for:

Baby/Toddler: ~17 inches around
Adult: ~21–22 inches around

Step 3: Shape the Crown

Once your squares are sewn into a circle, crochet around the top edge. You’ll work decrease rounds to close the top:

Join yarn at any seam.
Work single crochet or double crochet around, decreasing evenly (skipping every 5th or 6th stitch) until the opening closes.
Pull tight, fasten off.

Step 4: Crochet the Brim

Join yarn at the bottom edge of your square circle.

Round 1: Work single crochet evenly around.

Round 2: Work [2 single crochets in next stitch, 1 single crochet in next 3 stitches] around.

Round 3+: Continue working even rounds of single crochet, or alternate increase rounds with even rounds until the brim is as wide as you like.

Fasten off. Weave in all ends.

Customization Ideas

Two-toned hat: Switch colors every round for a striped granny effect .
Fur trim: Add a faux fur brim for winter vibes .
Flower accents: Sew a crochet flower to the side for extra cuteness.
Reversible: Make two hats and sew them together for a reversible design.

Troubleshooting Common Problems

Table:

Problem	Solution
Hat is too tight	Go up a hook size or add an extra cluster in the increase rounds .
Hat is too loose	Go down a hook size or skip an increase round.
Brim curls up	Your tension is too tight. Loosen up or use a larger hook for the brim.
Squares don’t line up	Count stitches carefully. All squares must be the exact same size before sewing.
Top has a hole	Pull the magic ring tail tighter, or work an extra decrease round.

Final Thoughts

There’s something special about wearing a hat you made yourself. When someone asks, “Where did you get that?” and you say, “I made it,” the look on their face is priceless. Granny square bucket hats are trendy, practical, and surprisingly easy. Whether you go with the seamless granny stitch or the patchwork style, you’re going to end up with a hat that’s uniquely yours.

So grab your hook, dig into that yarn stash, and start stitching. Summer (and compliments) await! 🧶☀️
