This adorable pink bubble stitch baby romper set is everything you want in a handmade baby gift. The matching bonnet and booties make it a complete layette that looks like it came from a boutique. And that gorgeous textured bubble stitch? It creates the coziest, squishiest fabric perfect for snuggling a newborn.
I know what you are thinking. A whole baby romper sounds intimidating. But here is the truth. If you can work basic stitches and follow a simple repeat, you can absolutely make this set. The bubble stitch pattern is rhythmic once you get going. Promise.
Let me walk you through everything you need to recreate this crochet baby romper pattern from scratch.
What You Are Making
This set includes three pieces:
1. Button-front baby romper with long sleeves and ribbed cuffs
2. Matching bonnet with tie closures
3. Coordinating booties with folded cuffs
The entire set uses the same bubble stitch texture throughout, giving it that cohesive, heirloom quality. Those sweet wooden heart buttons down the front add the perfect finishing touch.
Finished Sizes (0-6 months):
Skill Level
Intermediate. You should be comfortable with basic crochet stitches and working in the round. The bubble stitch requires a specific technique, but I will walk you through it step by step. If you have made a baby blanket or simple garment before, you are ready for this.
Materials Needed
Yarn:
Hooks:
Notions:
Gauge
Gauge matters for garments. Please take time to check yours.
Using 5.0mm hook in bubble stitch pattern:
If your gauge is off, adjust your hook size. Too many stitches per inch? Go up a hook size. Too few? Go down.
Abbreviations and Stitch Definitions
Let me define every stitch before we begin. Read through these so nothing surprises you mid-pattern.
ch = chain: Yarn over, pull through loop on hook. This creates your foundation.
sl st = slip stitch: Insert hook, yarn over, pull through stitch AND loop on hook in one motion. Used for joining and moving across stitches.
sc = single crochet: Insert hook, yarn over, pull up loop (2 loops on hook), yarn over, pull through both loops. Your basic short stitch.
hdc = half double crochet: Yarn over, insert hook, yarn over, pull up loop (3 loops on hook), yarn over, pull through all 3 loops. Slightly taller than sc.
dc = double crochet: Yarn over, insert hook, yarn over, pull up loop (3 loops on hook), yarn over, pull through 2 loops, yarn over, pull through remaining 2 loops. A tall, open stitch.
BLO = back loop only: Work into just the back loop of the stitch below, leaving the front loop unworked. Creates ribbed texture.
BS = bubble stitch: This is our star texture stitch. I will explain it fully below.
inc = increase: Work 2 stitches into the same stitch.
dec = decrease: Work 2 stitches together as one.
The Bubble Stitch Tutorial
This is the signature stitch that creates that beautiful puffy texture. Take your time learning it before starting the romper.
How to work the Bubble Stitch (BS):
1. Yarn over, insert hook into stitch
2. Yarn over, pull up a loop (3 loops on hook)
3. Yarn over, pull through 2 loops (2 loops remain)
4. Repeat steps 1-3 four more times, all in the SAME stitch (6 loops on hook)
5. Yarn over, pull through all 6 loops
6. Chain 1 to secure the bubble
The bubble pops forward toward you. On wrong side rows, the bubbles will naturally face the right side of your work.
Practice tip: Make a small swatch of 15 chains. Work a few rows alternating sc rows with bubble stitch rows until you feel confident.

Care Instructions
Troubleshooting Tips
Bubbles look flat? You may not be working enough loops into each bubble. Make sure you have 6 loops on your hook before the final pull-through.
Edges curling? Block your finished pieces by wetting and pinning flat to dry.
Gauge off? Remember that bubble stitches pull in the fabric width-wise. Your foundation chain should be slightly wider than your finished measurement.
Buttonholes too tight? Try ch 3 instead of ch 2 for the buttonhole openings.
