Last spring my best friend called in a mild panic. Her sister’s baby shower was three weeks away and she needed a handmade gift that would make everyone at the party say “wait, you made that?” I spent the next few days sketching on napkins and swatching yarn until this sunny yellow cardigan came together. The butter-yellow color looked exactly like duckling fuzz, so a tiny crocheted duck had to go on the front. When she handed over the finished sweater, her sister actually teared up—and that reaction is exactly why I keep designing these little garments.
About This Baby Cardigan Crochet Pattern
This cheerful baby sweater works from the top down with classic raglan construction. You start at the neckline and grow the whole piece in one go, so there is no seaming the body together later. The sleeves separate partway through and finish in the round, which keeps the process smooth and satisfying.
The texture comes from alternating rows of single crochet and half double crochet. Those two basic stitches create soft horizontal ridges without any complicated pattern repeats. If you can work sc and hdc, you can make this sweater.
The adorable duck applique crochets separately and sews on after blocking. Those little orange feet? Just surface slip stitches worked right onto the fabric. Cute without the stress.
Skill Level
This pattern sits at the intermediate level. You should feel comfortable working both flat and in the round, following raglan shaping, and picking up stitches along an edge. If you have already made at least two simple garments, you will do great here. The construction stays logical and the instructions walk you through every step.
Finished Measurements
This cardigan fits babies aged 6 to 12 months.
Chest circumference when buttoned measures 20 inches. Total length from back neck to hem hits 10.5 inches. Sleeve length from underarm to cuff runs 6.5 inches. Upper arm circumference sits at 7 inches.
Those numbers give a comfortable fit with a little room to grow. The fabric has enough stretch that it stays easy to put on wriggly little arms.
Materials Needed for This Crochet Baby Sweater
You need worsted-weight yarn (Category 4). The main color takes about 280 yards of butter yellow. You also need a small amount of white for the duck body and a scrap of orange for the beak and feet.
Good yarn options include Lion Brand Pound of Love (soft, machine-washable acrylic—two skeins will cover you), Cascade 220 Superwash for excellent stitch definition, or Paintbox Yarns Simply DK held double if you prefer that route.
Hooks: US size G-6 (4.00 mm) for the body and sleeves, US size F-5 (3.75 mm) for the neckband and cuffs, and US size E-4 (3.50 mm) for the duck applique.
Notions list is short: six wooden buttons about 15 mm across, a yarn needle, four locking stitch markers, scissors, and blocking mats with pins.
Gauge
With the larger hook in the body stitch pattern you want 16 stitches and 18 rows to equal 4 inches after blocking. Please make a gauge swatch. Chain 22, work the alternating sc and hdc pattern for 22 rows, block it, and measure the center. Gauge matters for garment fit—one hook size difference can change the chest measurement by about 1.25 inches. Skip this step and you risk a sweater that looks perfect on the hook but refuses to fit the baby.

Special Stitches and Techniques
The body stitch pattern is simple. On right-side rows you chain 1 and single crochet across. On wrong-side rows you chain 1 and half double crochet across. Alternate those two rows for the entire yoke and body.
Raglan increases happen on right-side rows. At each of the four markers you work single crochet in the stitch before the marker, move the marker up, work two single crochets in the next stitch, then single crochet in the following stitch. That sequence adds eight stitches total every increase row.
Pattern Notes Before You Begin
The cardigan works flat from the top down—do not join into a round during the yoke. Chain 1 at the start of every row does not count as a stitch. Place the raglan markers in the chain stitches between sections and move them up each row. Stitch counts in parentheses show the working stitches only. When you divide for the sleeves, park those stitches on scrap yarn. Block the finished sweater before you sew on the buttons or the duck applique. That last step keeps everything neat and professional-looking.
Step by Step Crochet Pattern Instructions
Start with the neckband on the smaller hook. Chain 66 and work a few rows of single crochet, including one back-loop-only row that creates a fold ridge. Switch to the larger hook and set up the yoke by placing the four raglan spines. Increase at those points on every right-side row while working even half-double-crochet rows on the wrong side. Keep going until the yoke reaches about four inches deep.
Divide for the body and sleeves by chaining underarm bridges and parking the sleeve stitches. alternating stitches, decrease a couple of times near the cuff, and add the matching border.
The front band is a simple single-crochet strip with six buttonholes. Fold and sew the neckband for a clean finish, attach the buttons, and crochet the duck applique separately. Sew the duck onto the left front, add the orange surface-slip-stitch feet, and you are done. The whole sweater looks sunny, cheerful, and completely handmade with love.
FAQ’s
Can a confident beginner finish this sweater?
If you already know single crochet and half double crochet and have made a couple of simple projects, yes. The raglan increases are the only new-ish part, and the pattern shows exactly where to place them. Take it one section at a time and you will be fine.
Is the duck applique hard to attach?
Not at all. Crochet it separately, block both the sweater and the duck, then sew it on with the yarn needle using matching yellow yarn. The orange feet are just surface slip stitches, so they go on in minutes.
Will the sweater stretch out of shape?
The alternating sc and hdc fabric has good structure. Block it once after finishing and it holds its shape through washes. Choose a yarn with some memory (acrylic or superwash wool both work well) and you are set.
Can I make this in a different size?
The base size is 6–12 months. You can add or remove increase rows in the yoke and adjust the body length to tweak the fit. Keep an eye on the stitch counts so the proportions stay balanced.
How many buttons do I really need?
Six wooden buttons look balanced and give a secure close. If you prefer fewer, space four evenly and it still works. Just make sure the buttonholes line up with the band.
What if my gauge is a little off?
Change hook size until you hit 16 stitches and 18 rows in 4 inches. A tighter gauge makes a smaller sweater; a looser gauge makes it bigger. Check early so you do not have to frog the whole yoke later.
Conclusion
This sunny yellow duckling cardigan is pure happiness in yarn form. The construction stays straightforward, the texture looks intentional, and that little duck on the front makes everyone smile. Grab your butter-yellow yarn, clear a couple of evenings, and make something that will be worn, photographed, and treasured. You will love every stitch.
