I call this one the Little Sunshine Romper, and it started its life in a notebook I keep tucked beside my craft chair. A dear friend announced she was expecting her first baby last spring, and I knew immediately that I wanted to make something cheerful and memorable. Something that felt like a tiny heirloom rather than just another handmade gift.
The sunflower motif came first. I sketched it out during a rainy afternoon, imagining golden petals against cream cotton and those sweet little wooden buttons at the shoulders. The whole design took shape from there, piece by piece, until I had a complete romper pattern that I genuinely could not wait to share.
Now this pattern lives here for you to make your own. Whether you are stitching for your own little one, a baby shower gift, or simply because you love the idea of tiny overalls with a flower on the front, I think you are going to love how this one comes together.
About This Crochet Pattern
This sunflower baby romper combines classic granny square construction with practical garment shaping. The result is a structured overall style romper featuring a decorative bib front panel, adjustable shoulder straps, and snap closures at the crotch for easy diaper changes.
The construction is modular, meaning you work separate pieces and then seam them together at the end. This approach makes the project feel manageable and allows you to block each section for crisp, professional results.
Skill level: Intermediate. You should be comfortable working in the round, joining with slip stitches, reading granny square patterns, seaming panels together, and working basic increases and decreases. If you have completed at least two flat projects and one in the round project, you can absolutely tackle this with patience.
Time estimate: Approximately 10 to 14 hours total, spread across multiple sessions. The sunflower motif alone takes about 1 to 2 hours. Assembly and finishing add roughly 1 hour at the end.
Finished Measurements
Size: 0 to 3 months

Materials You Will Need
Yarn
You will need DK weight yarn (also called Light 3) in three colors:
Recommended Yarn Options
Paintbox Yarns Simply DK (100% acrylic, 276 yards per 100g skein) in Vanilla Cream, Mustard Yellow, and Coffee Bean. This yarn offers excellent stitch definition, is machine washable, and is budget friendly.
Drops Safran (50% cotton, 50% acrylic, 175 yards per 50g skein) in Off White, Curry, and Dark Brown. The cotton content gives a softer drape and beautiful stitch clarity that works wonderfully for baby garments.
Lion Brand Comfy Cotton Blend (52% cotton, 48% polyester, 252 yards per 100g skein) in Linen, Goldenrod, and Espresso. Breathable and gentle against baby skin with easy care.
Choose any DK weight yarn with good stitch definition that feels soft and hypoallergenic. Avoid fluffy or hairy yarns because the texture will obscure the granny square lace openings and the sunflower petal detail.
Hook
US size E-4 (3.5 mm) crochet hook. Adjust as needed to meet gauge.
Notions
Gauge
18 single crochet stitches by 22 rows equals 4 inches (10 cm) worked flat in single crochet using Color A and US E-4 (3.5 mm) hook, blocked.
The sunflower granny square motif after Round 5 of the bib panel should measure approximately 5.5 inches (14 cm) square.
Gauge is critical for proper fit. Please make a swatch before beginning and adjust your hook size up or down as needed.
Abbreviations
Before we dive into the step by step instructions, here are all the abbreviations you will encounter:
Special Stitches Explained
Sunflower Petal Stitch
This creates a raised petal on the right side of the fabric by working around the post of a stitch from a previous round.
1. Insert hook from front to back around the post of the indicated double crochet from Round 1
2. Yarn over and pull up a long loop, approximately 0.75 inches (2 cm) tall
3. Yarn over and pull through 2 loops on hook
4. Yarn over and pull up another long loop around the same post
5. Yarn over and pull through 2 loops
6. Yarn over and pull through all 3 remaining loops on hook
This is essentially a front post cluster worked around a single post with two elongated yarn overs. One completed petal stitch sits on top of each double crochet post from Round 1.
sc2tog (Single Crochet Decrease)
1. Insert hook into next stitch, yarn over and pull up a loop (2 loops on hook)
2. Insert hook into following stitch, yarn over and pull up a loop (3 loops on hook)
3. Yarn over and pull through all 3 loops on hook
One stitch decreased.
Button Loop
1. At the designated location, join yarn with slip stitch
2. Chain 6
3. Slip stitch back into the starting stitch to form a loop
4. Work 7 single crochet around the chain 6 loop to stabilize it
5. Slip stitch to close and fasten off
Pattern Notes Before You Begin
1. The romper is worked in five separate pieces: the sunflower bib front panel, the back panel, two shoulder straps, and the lower body section.
2. All pieces are blocked before assembly. Blocking the granny square motif is especially important for neat corners.
3. The sunflower motif is worked in rounds from center outward using Colors C, B, and then A for the lace border.
4. Turning chains in single crochet rows do NOT count as a stitch throughout this pattern.
5. Right side (RS) of fabric faces out on all finished pieces. Mark the RS with a stitch marker on the first round of the granny square.
6. Join all rounds with a slip stitch to the first stitch of the round unless otherwise stated.
7. Fasten off and weave in all ends after each color section.
Section 1: Sunflower Motif (Bib Front Panel)
This beautiful centerpiece is worked in rounds from the center outward.
Round 1 (Color C, Dark Brown)
Make a magic ring.
Chain 3 (counts as first dc). Work 11 dc into the magic ring. Pull ring closed. Slip stitch to top of ch-3 to join.
(12 dc)
Round 2 (Color C continuing)
Ch 1. Work 2 sc in each stitch around. Sl st to first sc to join. Fasten off Color C.
(24 sc)
Round 3 (Color B, Golden Yellow, Petal Round)
Join Color B with sl st to any stitch of Round 2.
Ch 1.
Work 1 sc into the current stitch of Round 2. Then work 1 Sunflower Petal around the post of the corresponding dc from Round 1 directly below.
Each sc in Round 2 pairs with a petal worked into Round 1 below it. The sc sits behind the petal on the RS, and the petal pops forward.
Repeat: sc into next Round 2 stitch, then Sunflower Petal around the next Round 1 post, all the way around.
Work 24 sc total and 12 petals total.
Sl st to first sc. Do not fasten off.
(24 sc + 12 petals; working stitch count remains 24)
Round 4 (Color B, Second Row of Petals)
Ch 1.
Work 1 sc in each sc around (working behind the petals, into the sc stitches from Round 3).
Then work 1 larger Sunflower Petal around the post of each sc from Round 2. These are one row below Round 3 sc, creating a second, slightly longer ring of petals that fans out over Round 3.
This creates the layered petal effect seen on the finished sunflower.
Sl st to first sc. Fasten off Color B.
(24 sc working stitches; 24 petals as embellishment)
Note: The two rounds of petals (Rounds 3 and 4) create the full, layered sunflower petal effect. Round 3 petals are slightly shorter. Round 4 petals are slightly longer. Together they form approximately 24 visible petals surrounding the dark brown center.
Round 5 (Color A, Cream, Begin Granny Square Border)
Join Color A with sl st to any sc of Round 4.
Ch 4 (counts as dc + ch 1).

Join Color A in any corner ch-2 sp.
Ch 3 (counts as dc).
(2 dc, ch 2, 3 dc) in same corner sp. Corner made.
Ch 1.
(3 dc in next ch-1 sp, ch 1) x 5 times across the side.
(3 dc, ch 2, 3 dc) in next corner ch-2 sp. Ch 1.
Repeat for all 4 sides and corners.
Sl st to top of beg ch-3.
(84 dc, 24 ch-1 sp, 4 ch-2 corner sp)
Fasten off. Weave in all ends. Block flat to 5.5 inches (14 cm) square.
Checkpoint: The square should measure 5.5 inches on each side when blocked flat. The dark brown center, golden petals, and cream lace border should all be visible and flat with no curling.

Seaming the Legs
Fold the lower body piece in half widthwise (right sides together), so the 40 stitch row is at the top (crotch) and the cast on edge is at the bottom (leg openings).
Seam the top center using mattress stitch or slip stitch seam: seam from the top folded center point down approximately 2.5 inches for the crotch seam.
Then seam each side edge (the full length side seam of each leg) using mattress stitch.
Turn right side out. Two leg tubes should be formed, open at the bottom.
Leg Cuffs
Join Color A at the back seam of one leg opening with RS facing.
Round 1: Ch 1. Work 32 sc evenly around the leg opening. Sl st to first sc to join.
(32 sc)
Rounds 2 through 4: Ch 1. Work BLO sc in each sc around. Sl st to first sc to join.
(32 sc)
Fasten off. Repeat for second leg opening.
Working back loop only in rounds 2 through 4 creates the subtle ribbed texture visible at the leg cuffs.
Crotch Snap Placement
With a sewing needle and thread, attach 3 dark snap buttons evenly spaced across the crotch seam area. Space them approximately 0.75 inches apart centered at the crotch fold.
Section 4: Shoulder Straps (Make 2)

Work 1 sl st into edge of last row (to anchor).
Ch 6. Sl st back into same edge st to form loop.
Work 7 sc around the ch-6 loop to reinforce it.
Sl st to base. Fasten off.
This button loop end is the top of the strap. The opposite flat end will be sewn to the back panel shoulder tabs.
Make 2 straps total.
Section 5: Assembly
Step 1: Block All Pieces
Lightly wet block all panels. Pin the bib panel to exactly 5.5 inches square. Pin the back panel and straps flat. Allow to dry completely.
Step 2: Attach Lower Body to Bib Front Panel
Place the bib front panel (sunflower granny square) right side up. Align the bottom edge of the bib panel with the top edge of the lower body panel front half. Using Color A and a yarn needle, mattress stitch the bottom edge of the bib to the top edge of the lower body front.
Step 3: Attach Back Panel to Lower Body
Similarly, mattress stitch the bottom edge of the back panel to the top edge of the lower body back. Align side edges of front and back.
Step 4: Seam Sides
Using mattress stitch, seam the left side edge of the front bib to the left side edge of the back panel, from the underarm down to where the lower body panels meet. Repeat for the right side.
Step 5: Attach Shoulder Straps
The flat (non loop) end of each strap is sewn to the inside of the top corners of the back panel shoulder tabs. Use overcast stitch firmly through all layers.
Step 6: Attach Wooden Buttons to Bib Front
Position 1 wooden button at the top left corner of the bib panel and 1 at the top right corner, approximately 0.5 inches from the top and side edges. Sew through all layers firmly.
Step 7: Adjust Strap Length
Try the romper against a baby or doll form. The button loops on the straps fasten around the wooden buttons on the bib front. Adjust as needed before permanently finishing the back seam.
Finishing
Weave in all remaining ends using a yarn needle, working each end back through at least 1 inch of stitches in two directions.
To block the finished romper: Submerge in cool water, gently press out excess water (do not wring), lay flat on a blocking mat, pin the bib square to maintain sharp corners, and allow to dry completely.
