This original BabyYarnie crochet peplum baby cardigan pattern uses the supplied collage only as a visual mood reference. A fitted square-neck bodice with a separate joined fan-stitch peplum, cap sleeves and a back button opening. The written construction, stitch counts and shaping are independently developed and numerically reviewed.
This free tutorial is written as an original measured construction rather than a color-only variation. Read the complete pattern before beginning, make a washed gauge swatch, and record the selected size and every adjustment. The stitch audit checks the written arithmetic, but it does not claim a physical sample or fit test.
Development disclosure: The supplied collage is a visual mood reference only. This independently written tutorial has a numerical stitch audit, but no physical sample test is claimed. AI-generated illustrations are not photographs of a tested sample.

Gauge, Sizing and Planning
Wash and dry a generous swatch in the same yarn, hook and colorwork method planned for the project. Measure only the relaxed center. If the stitch gauge is too tight, move up a hook; if it is too loose, move down. Recheck row gauge because length and shaping depend on it. Parenthetical counts follow the listed size order throughout. Place removable markers at all shaping points and recount before moving to the next section.
Instructions
Square-Neck Bodice
- Ch 61. Row 1: hdc in third chain and across: 59 sts. Mark sections as 10 front, 8 sleeve, 23 back, 8 sleeve and 10 front, with marker stitches between sections.
- Rows 2, 4, 6 and 8: work 3 hdc in each of four marked raglan stitches and one hdc elsewhere, adding 8 stitches each increase row. Work odd rows even. Row 8 ends with 91 sts.
- Row 9 divide: hdc 14 front, hold 18 sleeve stitches, ch 4, hdc 27 back, hold 18, ch 4, hdc 14 front: 63 body positions.
- Rows 10–23: work 63 hdc in turned rows. On Rows 20–23, decrease one stitch at each front neck edge to square the opening while preserving 59 lower-bodice positions.

Cap Sleeves and Fan Peplum
- For each cap sleeve return 18 held stitches to the hook, work 4 hdc across the bridge and one in each corner gap: 24 sts. Work four joined rounds, decreasing two stitches on Round 4: 22 sts.
- Work one cream sc edging round over 22 sleeve stitches, then repeat on the second cap sleeve and compare both depths.
- Join plum at the lower bodice. Setup Row: distribute 60 sc evenly along the lower edge. Fan Row 1: repeat [skip 2, 5 dc in next stitch, skip 2, sc in next] ten times.
- Fan Rows 2–8: work dc into every fan stitch and sc into every anchor, adding one extra dc at the center of each fan on Rows 4 and 7 for gentle flare. Finish with a cream picot edge.

Back Opening and Finish
- Work five rows of cream BLO sc along each back edge and around the square neckline. Form four ch-2 buttonholes on the right band.
- Sew buttons opposite with doubled yarn or add four pairs of crochet ties. Reinforce the top closure behind the fabric.
- Wet-block the peplum fans open and keep the square neck corners crisp. Confirm a 20-inch chest and equal cap sleeves.
Finishing
- Secure every seam, pocket, collar and edging through several hidden paths.
- Wash and dry flat, then compare chest, body and sleeve measurements with the plan.
- Inspect closures and decorative stitches before supervised wear; remove the cardigan for sleep.

Tips
- Make and wash a generous gauge swatch.
- Recount after each shaping row and keep paired pieces together.
- Use crochet ties instead of buttons for a small-parts-free closure.
- Block textured stitches from the wrong side without crushing them.
Frequently Asked Questions
Can I resize this cardigan?
Recalculate from the washed gauge and preserve the shaping ratios; changing only hook size can distort the garment.
Can I substitute yarn?
Choose a soft washable yarn that matches the washed stitch and row gauge and gives suitable drape.
Are buttons required?
No. Securely anchored crochet ties are a practical small-parts-free alternative.
Conclusion
The finished project combines measured shaping, readable colorwork and practical finishing in one complete original crochet construction. Compare the finished measurements with the plan, confirm that every seam and carried strand is secure, and follow the yarn label for washing and storage.
