If you need a handmade baby gift that will make every new parent’s jaw drop, this is the project. These pastel granny square baby overalls combine classic crochet technique with a cheerful sunflower motif that works up into the most adorable little outfit you’ve ever seen. The construction uses DK weight yarn, beginner-friendly granny squares, and simple ribbed sections for the bib, straps, and cuffs.
This crochet pattern is sized for 12 to 18 month babies, making it perfect for baby showers, first birthdays, or that special little one in your life. The modular design means you can work on squares anywhere, anytime, then join them together when you’re ready. It’s also a fantastic stash buster if you’ve been hoarding pastels.
Whether you’re an experienced crafter looking for a satisfying project or an intermediate crocheter ready to level up, these overalls deliver. The finished garment features a relaxed wide-leg silhouette, button-closure shoulder straps, and the sweetest gathered ankle cuffs. Let’s get into it.
Why You’ll Love This Crochet Pattern
This baby overalls crochet pattern hits all the right notes. The granny square construction means no complicated shaping or tricky increases. You make individual squares, block them, join them together, and add the finishing touches. It’s methodical and satisfying.
The sunflower center motif at the heart of each square gives these overalls personality without requiring advanced skills. The color palette of soft lavender, mint green, blush pink, cream, and yellow creates that perfect pastel rainbow effect that photographs beautifully and looks stunning in person.
Every square uses the same stitch pattern, so once you’ve made your first one, you’ve got it. The repetition builds muscle memory and confidence. By square number five, you’ll be flying through them.
Materials You’ll Need
Gather these supplies before you begin. Having everything ready makes the process smooth and enjoyable.
Yarn (DK Weight, CYCA 3):
Recommended Yarn Options:
Hooks:
Notions:
Finished Measurements
These measurements are for the 12 to 18 month size:
Gauge (Don’t Skip This!)
Getting gauge right is mandatory for this garment. A square that’s too large makes baggy overalls. Too small makes them unwearable.
For squares (G-6 / 4.0 mm hook):
One completed granny square = 3.5 inches / 9 cm edge to edge after blocking
For ribbing (F-5 / 3.75 mm hook):
18 stitches x 22 rows in single crochet through back loop only = 4 inches / 10 cm
Make a test square before committing to all 30. Adjust your hook size up or down as needed.
Abbreviations and Stitch Definitions
Let me break down every abbreviation you’ll encounter. Understanding these makes the pattern much easier to follow.
Special Stitches Explained
Beginning Cluster (beg-cl):
Chain 3 (this counts as your first double crochet). Work 2 more double crochets into the same space, but don’t complete them fully. Draw up the last loop of each dc, then yarn over and pull through all loops on hook at once.
Cluster (cl):
Insert hook into the space, yarn over, pull up a loop, yarn over, pull through 2 loops. You now have 2 loops on your hook. Repeat this process 2 more times into the same space. You’ll have 4 loops on your hook. Yarn over and pull through all 4 loops.
JAYG Join:
When joining a new square to a completed one during the final round: instead of working a corner ch-2, work ch 1, slip stitch into the corresponding corner ch-2 space of the neighbor square, ch 1. For side ch-1 spaces, simply slip stitch into the matching space of the neighbor square instead of chaining.
Ribbing Row:
With F-5 hook and MC, chain the required number. Row 1: sc in 2nd chain from hook and in each chain across, turn. All following rows: ch 1, sc in BLO of each stitch across, turn. This creates stretchy, textured ribbing.
Sunflower Granny Square Instructions

Color sequence for every square:

Your finished square should measure 3.5 inches / 9 cm after blocking.
Block all 30 squares before proceeding. This step is not optional. Wet block by soaking in cool water for 15 minutes, gently pressing out excess water, and pinning to blocking mats at the correct dimensions.
Color Placement Guide
For a pleasing scattered pastel layout, make:
Arrange them in a checkerboard pattern when assembling.
Assembly: Joining Squares Into Panels
The overalls consist of two mirrored leg panels.
Each leg panel: 3 squares wide x 5 squares tall = 15 squares
Total: 30 squares
Use the JAYG method described in special stitches. Complete Round 4 fully on your first square without any joins. For each subsequent square, join on the appropriate edges during Round 4.
Start at the top-left corner of your panel. Work across the first row of 3 squares, joining each new square to its neighbor on the left. Begin the second row, joining each square’s top edge to the square above it. Continue until all 15 squares form a 3-wide by 5-tall rectangle.
Repeat for the second panel, mirroring the color placement.
Checkpoint: Each panel should measure approximately 10.5 inches / 26.5 cm wide by 17.5 inches / 44.5 cm tall.
Seaming the Panels Together
With right sides facing out, hold both panels with their long edges aligned.
Center front seam: Using MC and a yarn needle, whipstitch along one long edge from top to bottom.
Center back seam: Seam from the bottom upward, stopping after 2 squares from the bottom. Leave the top 3-square height open at the back.
Crotch seam: Bring the bottom edges of front and back panels together. Seam across the bottom of the two center squares to create the crotch curve.
Inseam: Fold one leg so edges meet, right sides together. Seam from ankle hem to crotch. Repeat for second leg.
Ribbed Bodice Bib
With F-5 hook and MC, ch 43.
Row 1: Sc in 2nd ch from hook and each ch across. Turn. (42 sc)
Rows 2-22: Ch 1. Sc in BLO of each st across. Turn. (42 sc per row)
Fold bib in half widthwise. Work a row of sc through both layers to seam the top edge closed. Fasten off.
Seam the side edges of the bib to the front waist opening, centering it on the front panel.
Ribbed Shoulder Straps (Make 2)
With F-5 hook and MC, ch 9.
Row 1: Sc in 2nd ch from hook and each ch across. Turn. (8 sc)
Rows 2-44: Ch 1. Sc in BLO of each st across. Turn. (8 sc per row)
Fasten off, leaving a 12-inch tail.
Sew 2 buttons at the top end of each strap, spaced approximately 0.75 inches apart. Attach the non-button end to the back waist edge, positioned about 2.5 inches from each side edge.
Ribbed Ankle Cuffs (Make 2)
With F-5 hook and MC, ch 9.
Row 1: Sc in 2nd ch from hook and each ch across. Turn. (8 sc)
Rows 2-46: Ch 1. Sc in BLO of each st across. Turn. (8 sc per row)
Fasten off, leaving a 12-inch tail. Seam short ends together to form a ring. Whipstitch the cuff to each ankle opening with ribbing running vertically.
Waist Edging
With G-6 hook and MC, join with sl st at any point along the back waist opening. Work 1 round of sc evenly around the entire waist opening, working approximately 1 sc per stitch and 3 sc in each corner. Sl st to first sc to join. Fasten off. (approximately 84-88 sc)
Size Customization Tips
6-12 months: Work only 3 rounds per square using an F-5 hook throughout. Reduce panels to 3 squares wide by 4 squares tall.
2T: Increase panels to 3 squares wide by 6 squares tall. Add 6 rows to bib, straps, and cuffs.
3T-4T: Work 4 squares wide by 6 squares tall per panel (48 squares total). Adjust bib width to 56 sc.
Care Instructions
Machine wash on gentle cycle in cold water for acrylic or cotton-acrylic blends. Lay flat to dry. Do not tumble dry. Hand wash only for wool-blend yarns. Store folded flat to preserve shape.
