There's something undeniably sweet about a handmade sun hat on a little one. This pattern came together last spring when my niece needed something that actually stayed on her head and blocked the sun during playground hours. The brim is wide enough to shade little faces, and that popcorn flower on the front band? It's the detail that makes strangers stop and ask where you bought it.
Instead of making individual granny squares and stitching them together, this hat is worked seamlessly in the round from the crown down. The popcorn flower is crocheted separately as an appliqué and stitched onto the finished hat band — which means you can customize placement, swap colors, or even add multiple flowers if you're feeling bold. The entire project uses basic stitches: chain, single crochet, half double crochet, and double crochet. The popcorn stitch is the only "fancy" move, and it's really just five double crochets worked into one spot and joined at the top.
This pattern covers sizes newborn through 3 years, with clear notes for adjusting. One hat takes about 120 yards of worsted cotton for the main color and scraps for the flower. If you've made a simple beanie before, you already have the skills. If you haven't, this is a wonderful first shaped project.
Why You'll Love This Popcorn Flower Sun Hat
Most crochet sun hats are either too floppy, too stiff, or require sewing together panels that never quite match. This one is worked in continuous spirals for the crown, then joined rounds once the brim begins. No seams, no sewing panels, no gaps where the sun sneaks through. The single crochet fabric is dense enough to block UV rays yet breathable thanks to cotton's natural properties.
The popcorn flower is the real charmer here. It uses roughly 15 yards of yarn total — perfect for those little scrap balls you can't bear to throw away. Make the petals in yellow and the center in brown for a daisy vibe. Do cream petals with a mustard center for something more understated. Or go bold with hot pink petals and a white center. The flower is attached with a few whip stitches around its edge, so you can even swap them out seasonally if you're feeling crafty.
I've seen textured flower accessories trending steadily on Ravelry's baby and toddler categories through early 2026. Parents and gift-givers alike gravitate toward practical items with a handmade touch, and this hat delivers both. It's also a one-evening project — start after dinner and you'll be weaving in ends before bed.
Materials Needed
Yarn
- Main Color (MC): 120 yards of worsted weight (#4) cotton. Lion Brand 24/7 Cotton in "Ecru" or "Cream" ($5.99 per 186-yard skein at Joann). You'll need one skein. The mercerized finish gives a subtle sheen and holds the brim shape beautifully.
- Flower Petals (CC1): About 12 yards of worsted cotton in your petal color. Paintbox Yarns Cotton Aran in "Dusty Rose" or "Sage Green" ($4.99 per 93-yard skein at LoveCrafts).
- Flower Center (CC2): About 5 yards of worsted cotton in brown or gold. Lily Sugar'n Cream in "Warm Sand" ($2.49 per ball at Michaels) works perfectly and one ball makes dozens of flower centers.
Hooks & Notions
- H/8 (5.0 mm) crochet hook for the hat body. A Clover Amour ($8.99) is worth it here — you'll be doing a lot of single crochet.
- G/6 (4.0 mm) crochet hook for the flower appliqué only. Tighter gauge keeps those popcorn petals crisp and defined.
- Four locking stitch markers for marking round beginnings and brim increase points.
- Tapestry needle with a bent tip for weaving and flower attachment.
- Measuring tape for sizing the crown diameter.
Best Yarn Choices for a Structured Sun Hat
A sun hat lives outdoors — it gets sweated on, tossed in beach bags, and pulled on by tiny determined hands. Mercerized cotton is the gold standard because the mercerization treatment strengthens the fiber and prevents the brim from going limp after an hour in humidity. I've used Lion Brand 24/7 Cotton for all my sample hats, and the brims still stand crisp after a full summer of abuse.
If mercerized cotton isn't in the budget, standard kitchen cotton like Lily Sugar'n Cream or Peaches & Creme ($2.49 per ball) works fine with one caveat: it's stiffer to crochet and the finished hat feels slightly more rustic. That said, it holds its shape well and only softens a bit with washing. Avoid 100% acrylic — it offers zero UV protection, stretches when damp, and pills faster than you'd believe on a hat that rubs against car seat headrests.
Substitution rule of thumb: Stick with plant fibers. A cotton-linen blend like Lion Brand's Touch of Linen ($6.99 per skein) gives a lovely drape and breathability, though the linen content makes it slightly rougher on hands during crocheting. For gifting, I recommend the mercerized option — the sheen makes it look more polished and "store-bought" in the best way.

Gauge, Size Guide & Must-Have Tools
Gauge: 14 sc x 16 rows = 4 inches (10 cm) with H/8 (5.0 mm) hook in single crochet.
Crown diameter determines the entire hat fit. For a 0-3 month size, aim for a crown diameter of 4.5 inches. For 3-6 months, 5 inches. For 6-12 months, 5.5 inches. For 1-3 years, 6 inches. The pattern stops crown increases once you hit the target diameter for your size, then works even for the sides.
Make a gauge swatch in single crochet before starting. If your stitch count is off by even one stitch per inch, the crown diameter compounds that error across every round. Better to discover it on a 4-inch square than five rounds into the crown.
Size Adjustments:
- Larger head circumference: Continue crown increase rounds until the diameter matches (head circumference divided by 3.14) before starting the sides.
- Deeper hat: Add even rounds between the crown completion and the brim start. Each added round adds roughly 0.25 inches of depth.
- Wider brim: Add additional increase rounds to the brim section. Each round adds about 0.5 inches to the brim width.

Pattern Notes & Tips Before You Start
Working in Spirals vs. Joined Rounds: The crown is worked in a continuous spiral to avoid visible seam lines. Use a locking stitch marker in the first stitch of each round and move it up as you go. When you reach the sides, switch to joined rounds so the brim sits level. For guidance on when to use each method, see my spiral vs. joined rounds guide.
Popcorn Stitch Tips: Keep your tension even across all five double crochets in each popcorn. If one is looser than the others, the petal will look lopsided. Pull the closing chain tight — it locks the popcorn and prevents it from sinking back into the fabric. If you're new to the stitch, practice three or four on a swatch first. The motion becomes muscle memory surprisingly fast.
Flower Placement: Don't attach the flower until the hat is completely finished and you've tried it on the intended wearer (or a similarly-sized stand-in). Centering on the front band looks classic; offsetting slightly to one side gives a jauntier, more modern feel. Use pins to test placement before committing with your tapestry needle.
Brim Stiffness: If your brim feels too floppy after finishing, a light spritz with spray starch (about $4 at any grocery store) and a quick press with a cool iron will add just enough stiffness without becoming crunchy.

Step-by-Step Popcorn Flower Sun Hat Pattern
Part 1: The Crown (Worked in Spiral)
Sizes: Newborn (0-3 mo, 3-6 mo, 6-12 mo, 1-3 yr)
Crown Target Diameter: 4.5" (5", 5.5", 6")
Foundation: With MC and H/8 (5.0 mm) hook, make a magic ring.
Round 1: Ch 1, work 6 sc into ring. Do not join. Place marker in first sc. (6)
Round 2: 2 sc in each st around. (12)
Round 3: *Sc in next st, 2 sc in next st; rep from * around. (18)
Round 4: *Sc in next 2 sts, 2 sc in next st; rep from * around. (24)
Round 5: *Sc in next 3 sts, 2 sc in next st; rep from * around. (30)
Round 6: *Sc in next 4 sts, 2 sc in next st; rep from * around. (36)
Continue this increase pattern — each round adds 1 more sc between increases — until your crown diameter reaches the target for your chosen size. For reference: Newborn stops around Rnd 6, 3-6 mo around Rnd 8, 6-12 mo around Rnd 10, 1-3 yr around Rnd 12.
Part 2: The Sides (Switch to Joined Rounds)
Once the crown reaches the target diameter, begin joining rounds with a sl st.
Next Round: Ch 1, sc in each st around, sl st to first sc to join.
Repeat this round until the hat depth from crown center to bottom edge measures 4" (4.5", 5", 5.5") for your size. This is the hat body before the brim begins.
The sides should be worked even — no increases. Place a marker at the join seam so you can count rounds easily. For keeping track of rounds, my guide on how to keep track of rounds has helpful tips.
Part 3: The Hat Band (Textured Detail)
This round creates a subtle ridge that defines the transition from hat body to brim.
Band Round: Ch 1, sc in BLO of each st around, sl st to join.
Part 4: The Brim (Worked in Joined Rounds)
Brim Round 1: Ch 1, *sc in next 2 sts, 2 sc in next st; rep from * around, sl st to join.
Brim Round 2: Ch 1, sc in each st around, sl st to join.
Brim Rounds 3-4: Rep Brim Rounds 1 and 2 once more.
Brim Round 5: Ch 1, *sc in next 3 sts, 2 sc in next st; rep from * around, sl st to join.
Brim Round 6: Ch 1, sc in each st around, sl st to join.
Brim Rounds 7-8: Rep Brim Rounds 5 and 6 once more.
Final Brim Round: Ch 1, reverse sc (crab stitch) in each st around. This creates a firm, non-curling edge. Sl st to join, fasten off, weave in end.
For more on getting clean, non-curling edges, see my guide on achieving straight edges in crochet.
Part 5: The Popcorn Flower Appliqué
Worked separately with G/6 (4.0 mm) hook for denser, crisper petals.
Center: With CC2, make a magic ring.
Round 1: Ch 1, work 8 sc into ring. Sl st to first sc. Fasten off CC2, leaving a 6-inch tail for attachment. (8)
Petals: Attach CC1 to any sc of the center.
Round 2: Ch 1, *PC in next st, sl st in next st; rep from * around. You'll have 4 petals total. After the last PC, sl st to the base of the first petal. Fasten off, leaving a 12-inch tail.
Each PC (popcorn): 5 dc in same st, remove hook from loop, insert hook into first dc of the group, grab dropped loop, pull through, ch 1 to close.
Part 6: Assembly
Step 1: Try the hat on the intended wearer or a suitable model. Pin the flower to the hat band where it looks best — centered is classic, slightly off-center is playful.
Step 2: Thread the flower's tail onto your tapestry needle. Whip stitch around the edge of the flower center, catching the hat band fabric securely but keeping stitches invisible on the hat interior.
Step 3: Thread the petal tail and make a few hidden stitches through the back of the petals into the hat band to tack down any petals that lift.
Step 4: Weave all remaining ends into the hat interior using the split-the-plies method so nothing pops loose in the wash.
Easy Variations & Custom Ideas
Multi-Flower Cluster: Make three smaller flowers by reducing the center to 6 sc and making 3 petals each. Cluster them asymmetrically on one side of the band for a garden-party look.
Striped Hat Body: Change colors every 4 rounds on the sides for a subtle stripe effect. Carry the unused yarn up the inside and catch it every few rounds to minimize loose ends. My how to change colors in crochet guide covers the cleanest methods.
Chin Strap Addition: For babies who yank hats off, attach a 50-chain tie on either side of the inner band. Thread through the band from inside to outside, knot on the outside, and chain the length needed to tie loosely under the chin.
Adult Version: Continue the crown increases until diameter equals your head circumference divided by 3.14. The pattern scales indefinitely — just keep increasing crown rounds until you hit your number.
Common Troubleshooting and Fixes
"My crown is wavy, not flat." You're increasing too quickly or your tension loosened. Check that you're following the increase pattern precisely — each round should add exactly 6 stitches total. If the crown ruffles, rip back one round and rework with slightly tighter tension. See my guide on fixing wavy crochet.
"The brim flips up instead of lying flat." This usually means your brim increases are too aggressive, or your gauge tightened. Try removing one increase round and replacing it with an even sc round. The crab stitch edge also helps weight the brim down.
"My popcorn petals look flat and sad." Make sure you're working a full 5 dc into the same stitch — not 4, not 4 and a half. Also check that your closing chain is snug. A loose chain lets the popcorn sink back. Practice on a swatch until each petal pops forward proudly.
"The hat is too short/tall." Depth is the easiest fix. Add or remove even sc rounds in the sides section before the band. Each sc round equals roughly 0.25 inches. More tips in my common crochet mistakes guide.
Next-Level Tips
Blocking Cotton Hats: Fill a bowl with cool water, submerge the finished hat for 10 minutes, gently squeeze out excess (don't wring the brim), and lay flat on a towel. Shape the brim into a perfect circle and let dry completely. The brim will hold its blocked shape through multiple wears.
Sun Protection Boost: Hold the finished hat up to a window. If you see light poking through individual stitches, the hat is more decorative than protective. Lining the interior crown with a circle of lightweight cotton fabric (about $3 for a fabric quarter) takes 20 minutes with a needle and thread and adds real UV blocking.
Gift-Worthy Finishing: Fold the hat and tuck it into a clear cellophane gift bag with a sprig of dried lavender. It smells amazing, looks intentional, and protects the hat from dust until gifted. Total cost: about $1.50 for presentation that feels premium.
Final Thoughts
This little sun hat has become my signature baby shower gift. It works up fast enough that I can make one during a lazy Sunday afternoon, and the popcorn flower always gets a delighted reaction when the gift bag opens. I've made them in creams, soft pinks, sage greens, and once in a sunny butter yellow with a white flower that looked like a daisy in full bloom.
If this is your first shaped hat, be patient with the crown increases. By the fourth or fifth round, the rhythm will feel natural, and you'll be amazed at how quickly the circle grows into something recognizable. Tag me or leave a comment when you finish — I'd love to see your versions out in the wild, keeping little heads shaded.
