This original BabyYarnie mint green granny square baby cardigan free crochet pattern turns the supplied photograph into an independently written crochet construction. A true modular 6–12 month cardigan made from eight full mint-and-cream granny squares: four for the back and two for each front. Add separate granny-stripe sleeves, cream bands and one cream patch pocket. Not a shoulder-yoke granny tile. The photograph guides color, proportion and styling only; it is not a source of written instructions or stitch counts.
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 photograph is a mandatory visual design reference only. This independently written BabyYarnie tutorial has a numerical stitch audit, but no physical sample test is claimed. The AI-generated design illustrations are not photographs of a tested sample; follow the written counts and swatch before use.

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
Crochet Eight Full Granny Squares
- With mint, make a magic ring. Round 1: ch 3 (not counted), work 12 dc in the ring, join and mark stitches 1, 4, 7 and 10 as corners: 12 sts.
- Round 2: work 3 dc in each marked corner stitch and 1 dc in every other stitch: 20 sts. Move each corner marker to the center dc of its three-dc group.
- Round 3 in cream: repeat the corner rule: 28 sts. Round 4 in mint: repeat: 36 sts. Round 5 in cream: repeat: 44 sts. Fasten off.
- Block the square to exactly 5 inches with straight sides and four equal corners. Make eight identical squares, matching color-change direction and final-round tension.
Assemble the Modular Body and Sleeves
- Back: seam four squares in a 2-by-2 grid. Each front uses two squares stacked vertically, producing one 5-by-10-inch panel. Join the front panels to the outer back edges at the shoulders for 3 inches, leaving a centered neck opening.
- Seam each front side to the back for 5 inches from the lower edge, leaving the upper 5 inches open for the sleeve. The assembled body measures about 20 inches around.
- For each sleeve, ch 25 with mint and work 24 hdc across. Work 24 rows, alternating four mint rows with two cream granny-texture rows made as [3 dc in one stitch, skip 2] across while preserving the 24-position width on the next hdc row.
- Seam the sleeve rectangle lengthwise, fit its 10-inch top edge into one armhole and sew without gathers. Add six cream BLO-sc rounds at the 24-stitch cuff. Repeat and compare both sleeves.
Add Bands, Buttons and Pocket
- With cream and the smaller hook, work one round of sc around the lower edge, maintaining the natural 88-stitch perimeter across the eight square edges. Add five BLO-sc rounds.
- Work cream sc evenly up the first front, around the neck and down the second front. Add four more BLO-sc rows. On the right band make four evenly spaced ch-2 buttonholes; use crochet ties instead for a small-parts-free closure.
- Pocket: with cream ch 17, hdc in third chain and across: 15 sts. Work 11 more rows, then one sc edging round. Block to about 3.25 inches square.
- Center the pocket on the lower square of the wearer's left front, 1 inch above the hem. Sew the two sides and lower edge through every row end, leaving the top open; tug-test the seam.
Finishing
- Steam-free wet-block all squares before seaming and let them dry completely.
- Reinforce square intersections and sleeve underarms with a second hidden pass.
- Measure 20-inch chest, equal sleeve lengths and unobstructed buttonholes; inspect all closures before wear.
Tips
- Make and block all eight squares before assembly.
- Keep the center dc marked at each corner.
- Seam in the same direction for a smooth inside.
- If a square differs by more than one-quarter inch, remake it rather than stretching it.
Frequently Asked Questions
Is this a full granny-square cardigan?
Yes. The body uses eight complete squares: four back and two on each front.
How is it different from a granny yoke?
The squares form the full body panels; they are not a decorative shoulder band.
Can I add a second pocket?
Yes. Make an identical 15-stitch pocket and mirror its placement.
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.
