Introduction
There’s nothing quite like wrapping a new baby in something you made with your own two hands. I had this in mind the whole time I was designing this set — every stitch was imagined landing in a grandmother’s arms at the first cuddle. And let me tell you, this little romper has earned its place at the top of my gift-making list.
The moss stitch is the real star here. It gives the fabric this lovely woven look, but it’s not a bit fussy to work — just single crochets and chains doing a pretty dance together. Then those matching booties? They take the whole set from sweet to heirloom-worthy. If you’ve ever handed a new mama a handmade gift and watched her face light up, you know exactly why we make things like this. And here’s my promise: this is absolutely within your reach.
Why This Baby Romper Pattern Works So Well
What you’re making is a sleeveless overall-style romper with adjustable button shoulder straps, the sweetest little front chest pocket, and ribbed leg openings that stay put without pinching. To match, the booties repeat that same textured body and finish with a cozy ribbed cuff.
I worked the entire set in moss stitch — also known as linen stitch or granite stitch. It builds a dense, gently raised fabric with a woven look that photographs like a dream and washes up beautifully. It’s nothing more than single crochets paired with chain spaces, staggered from row to row.
Construction-wise, the romper is two flat panels — front and back — worked from the bottom up. Once both panels are done, you’ll join the sides, work the leg ribbing, add the straps, and finish with the pocket. The booties start at the toe and are worked in the round. Nothing wild here, just good solid techniques that add up to a very professional-looking finish.
Skill Level and Time Estimate
I’d call this one intermediate. The moss stitch itself is simple enough, but you’ll want steady, even tension across a lot of rows. Plan on seaming two flat panels, picking up stitches around the curved leg openings, and shaping the booties entirely from scratch.
If you’re a confident beginner who’s finished a few garments before, don’t let that scare you off — you can absolutely tackle this. Just give the seaming sections your full attention, and whatever you do, don’t skip the gauge swatch.
Here’s a rough idea of the time each part takes:
- Romper body: 6 to 8 hours
- Shoulder straps and pocket: 1 hour
- Leg ribbing and finishing: 1 to 2 hours
- Booties: 2 to 3 hours
- Total estimated time: 10 to 14 hours

Materials You Will Need
Yarn: Approximately 300 yards / 275 meters of DK weight (Light 3) yarn in sage green
Hooks:
- US size G-6 / 4.0 mm crochet hook (for main body)
- US size E-4 / 3.5 mm crochet hook (for ribbing and booties)
Notions:
- 6 white four-hole buttons, approximately 5/8 inch / 16 mm diameter (4 for shoulder straps, 2 for pocket decoration)
- Yarn needle for seaming and weaving ends
- At least 4 stitch markers
- Scissors
- Measuring tape
Yarn Suggestions
Option 1: Lion Brand Feels Like Butta in Sage — DK weight, 100% polyester, 218 yards per skein. Soft, machine-washable, with an even twist that keeps the moss stitch nice and crisp. Plan on approximately 2 skeins.
Option 2: Paintbox Yarns Simply DK in Spearmint or Grass Green — budget-friendly, easy-to-find acrylic with great stitch definition. Plan on approximately 3 skeins.
Option 3: Paintbox Yarns Cotton DK in Stormy Green — cotton gives a denser, more structured fabric that’s wonderful for warmer weather. Swatch carefully, since cotton doesn’t stretch the way wool blends do. Plan on approximately 3 skeins.
Any DK weight yarn that hits the stated gauge may be substituted. For baby makes, lean toward machine-washable yarns and skip novelty or heavily textured ones — they’ll swallow the moss stitch texture.
Gauge
Using G-6 / 4.0 mm hook in moss stitch pattern:
18 stitches x 24 rows = 4 inches x 4 inches / 10 cm x 10 cm
For ribbing sections using E-4 / 3.5 mm hook in back loop only single crochet ribbing:
20 stitches x 22 rows = 4 inches x 4 inches / 10 cm x 10 cm
Gauge really matters on a fitted garment like this. Make your swatch larger than 4 inches on each side so the edges don’t throw off your count. Change hook size if you need to before you cast on for real.

Special Stitches
Moss Stitch (also called granite stitch or linen stitch)
This one builds a dense, woven-looking fabric. Here’s how it works in flat rows:
Row 1 (RS): Ch 1, sc in first st, ch 1, sk 1 st, (sc in next st, ch 1, sk 1 st) across to last st, sc in last st. Turn.
Row 2 (WS): Ch 1, sc in first st, ch 1, sk ch-1 sp, (sc in next sc, ch 1, sk ch-1 sp) across to last st, sc in last st. Turn.
Repeat Row 2 for pattern.
Important note: In this pattern, stitch counts refer to the total number of single crochet stitches only, not counting chain spaces.
Back Loop Only Single Crochet Ribbing (BLO sc rib)
Work all sc stitches through the back loop only. This creates a stretchy ribbed fabric.
Row 1: Sc in 2nd ch from hook and in each ch across. Turn.
Row 2 onward: Ch 1, sc BLO in each st across. Turn.
Single Crochet Two Together (sc2tog)
Insert hook into next st, yo and pull up a loop (2 loops on hook). Insert hook into following st, yo and pull up a loop (3 loops on hook). Yo and draw through all 3 loops. One decrease made. This reduces 2 stitches to 1 stitch.
Pattern Notes Before You Begin
- You’ll build the romper in two flat panels — front and back. Each panel works up from the bottom crotch edge through the body and bib section. The side seams come together once both panels are complete.
- The front panel runs taller than the back, thanks to the bib extension above the chest.
- Crochet the shoulder straps separately and sew them to the back top edge. Sew the buttons onto the front bib’s top corners; the strap buttonholes let you adjust the length.
- Leg openings are finished after seaming by picking up stitches around the opening and working BLO sc ribbing in the round.
- The moss stitch is worked over an even number of working stitches. The foundation chain must be odd.
- When working moss stitch, the ch 1 at the beginning of each row does NOT count as a stitch.
- Mark the RS of your work with a stitch marker at the beginning to keep track of orientation.
- All stitch counts in parentheses at the end of a row refer to sc stitches only.
Romper Front Panel Instructions
You’ll build the front panel from the bottom edge up, through the body and into the bib.
Foundation: Ch 39.
Row 1 (RS): Sc in 2nd ch from hook, ch 1, sk 1 ch, (sc in next ch, ch 1, sk 1 ch) across to last ch, sc in last ch. Turn. (20 sc)

Fasten off. Weave in ends.
Checkpoint: The completed front panel should measure approximately 10.5 inches / 26.5 cm from foundation to top of bib, and 8 inches / 20.5 cm wide.
Romper Back Panel Instructions
The back panel stops at underarm level — no bib here — so it’s shorter than the front.
Foundation: Ch 39.
Row 1 (RS): Sc in 2nd ch from hook, ch 1, sk 1 ch, (sc in next ch, ch 1, sk 1 ch) across to last ch, sc in last ch. Turn. (20 sc)

Rows 3 through 46: Rep Row 2. Turn at end of each row. (20 sc each row)
Top edge of back panel:
Row 47: Ch 1, sc in each sc and each ch-1 sp across. Turn. (39 sc)
Row 48: Ch 1, sc in each sc across. Turn. (39 sc)
Fasten off. Weave in ends.
Checkpoint: The completed back panel should measure approximately 7.5 inches / 19 cm from foundation to top edge, and 8 inches / 20.5 cm wide.
Seaming the Panels
Place front and back panels with RS facing each other. Align the bottom edges and side edges.
Using a yarn needle and matching yarn, seam the right side edge from the bottom corner up approximately 5 inches / 12.5 cm. This creates one side seam and leaves the upper portion open as the leg opening and armhole.
Seam the left side edge from the bottom corner up approximately 5 inches / 12.5 cm in the same manner.
The remaining unseamed portion above the side seams on each side forms the armhole openings. Turn RS out.
Leg Opening Ribbing Instructions
Work the ribbing for each leg opening separately using the E-4 / 3.5 mm hook.
Attach yarn at the inside seam of one leg opening with a sl st.
Set up rnd: Ch 1, sc evenly around the leg opening, placing approximately 36 sc evenly around the entire opening. Sl st to first sc to join. Do not turn. (36 sc)
Rib Rnd 1: Ch 1, sc BLO in each sc around. Sl st to first sc. (36 sc)
Rib Rnd 2: Ch 1, sc BLO in each sc around. Sl st to first sc. (36 sc)
Rib Rnd 3: Ch 1, sc BLO in each sc around. Sl st to first sc. (36 sc)
Rib Rnd 4: Ch 1, sc BLO in each sc around. Sl st to first sc. (36 sc)
Fasten off. Weave in ends.

Size Customization Tips
For 3-6 months:
- Increase foundation chain to ch 43 (yields 22 sc across)
- Work body section through Row 52 instead of Row 46
- Extend bib section through Row 72 instead of Row 66
- Add 2 additional rounds to leg ribbing (6 rounds total)
- Target finished chest circumference: approximately 18 inches / 45.5 cm
For 6-12 months:
- Increase foundation chain to ch 47 (yields 24 sc across)
- Work body section through Row 58 instead of Row 46
- Extend bib section through Row 80 instead of Row 66
- Add 4 additional rounds to leg ribbing (8 rounds total)
- Target finished chest circumference: approximately 20 inches / 51 cm
Strap length can be increased or decreased by 4 rows at a time to adjust length without affecting button placement.
Finishing and Blocking Your Baby Romper
Weave in all remaining ends securely, burying the tail under at least 1 inch of stitches.
Wet blocking is strongly recommended. Fill a basin with cool water and soak the finished romper and booties in it. Gently press out the extra water — don’t wring it. Spread it flat on a blocking mat, pinning it out to the finished measurements. Allow to dry completely, which takes 12 to 24 hours depending on humidity.
For acrylic yarn, steam blocking works better. Hold a steam iron about 1 inch above the fabric and let the steam work through it. Never set the iron directly on the crochet.
Blocking evens out the moss stitch texture beautifully and leaves the fabric nice and soft.
Attach all the buttons firmly with strong thread or thin yarn. Where the fabric will take a lot of tugging — especially the strap attachment points — pop a small flat button on the WS as backing for extra strength.
Care Instructions
- Wash by hand in cool water with a gentle baby-safe detergent
- If your yarn is machine washable, a delicate cycle in a mesh laundry bag works too
- Reshape while damp, then lay flat to dry
- Skip the tumble dryer, direct ironing, and dry cleaning
- Fold for storage rather than hanging, so it doesn’t stretch out
- Check the buttons now and then, and reinforce any loose stitching
You Made It!
Thanks for stitching along — I hope this little sage green romper turned out just the way you pictured it. That moss stitch texture is a beauty, and the matching booties complete the set.
