Let's dive into everything you need to create this beautiful romper for the 12-18 month size.

Materials Needed

Before you begin, gather these supplies. The pattern calls for worsted weight cotton, which gives excellent stitch definition and breathability—ideal for warm weather.

Yarn

• Worsted weight cotton or cotton blend (e.g., Lion Brand 24/7 Cotton)
• Sage Green – approximately 200 yards (for back panel and accents)
• Cream – approximately 200 yards (for front panel)
• Butter Yellow – approximately 150 yards (for sleeves)

Needles & Notions

• US Size 6 (4.0 mm) knitting needles (straight or circular for flat knitting)
• Tapestry needle for weaving in ends and seaming
• Stitch markers (at least 2)
• Scissors
• Measuring tape

Gauge

20 stitches and 28 rows = 4 inches in stockinette stitch, after blocking. Always knit a gauge swatch first to ensure your finished romper matches the intended measurements.

Step-by-Step Instructions

This pattern is worked flat in pieces and seamed together. The lace panel is simpler than it looks—once you get the 4-row repeat going, it becomes rhythmic and meditative.

Sizing & Abbreviations

Size: 12-18 months (finished chest: 20 inches, length: 18 inches)

Abbreviations:

• K = knit
• P = purl
• K2tog = knit two together (decrease)

Special Stitch Pattern: Lace Panel (multiple of 6 + 1)

This 4-row repeat creates the delicate, airy texture that defines the front of the romper.

• Row 1 (RS): K1, *YO, K2tog, K3; repeat from * to end of panel.
• Row 2 (WS): Purl all stitches.
• Row 3: K1, *K2tog, YO, K3; repeat from * to end of panel.

Repeat Rows 1-4 for the lace pattern. The yarn overs create the holes, and the K2tog keeps the stitch count consistent.

Back Panel (Sage Green)

This is the simplest piece—perfect for getting into the rhythm of the project.

Finishing & Assembly

This is where the romper comes together. Take your time with the seams for a polished, professional finish.

2. Set in the sleeves: Match the center of the sleeve cap to the shoulder seam, then sew the sleeves into the armholes.
3. Sew the side and sleeve seams in one continuous line for a clean finish.
4. Neckline: With RS facing, pick up and knit 40 stitches around the neckline.
5. Work in K1, P1 ribbing for 3 rows.
6. Bind off in pattern (knit the knits and purl the purls as you bind off).
7. Weave in all ends carefully with the tapestry needle.
8. Block to measurements: Soak the romper in lukewarm water, gently squeeze out excess, and lay flat to dry, pinning to the finished measurements (chest 20 inches, length 18 inches). Blocking helps even out the lace and gives the cotton a beautiful drape.
