Free Leaf Lace Baby Sweater Pattern | Knit Round Yoke Pullover
There is something deeply satisfying about knitting for a baby. The projects are small enough to finish in a reasonable amount of time, yet meaningful enough to become treasured keepsakes. A hand-knitted sweater, especially one worked in a delicate lace pattern, carries a kind of warmth that goes far beyond wool. This free leaf lace baby sweater pattern gives you everything you need to create a stunning round yoke pullover that looks far more complex than it actually is to knit.
Whether you are a seasoned knitter looking for a new project or an adventurous intermediate knitter ready to try lace for the first time, this pattern is designed to guide you every step of the way. The round yoke construction is forgiving and elegant, the leaf lace motif adds visual interest without requiring advanced techniques, and the finished sweater will be something any parent or grandparent would be thrilled to receive.
Let’s dive in.
Why Knit a Round Yoke Baby Sweater?
Round yoke sweaters have enjoyed a surge in popularity over the past several years, and for good reason. The construction method — knitting the body and sleeves separately before joining them at the yoke — eliminates the need for complicated set-in sleeves or shoulder seaming. The result is a sweater that fits beautifully, lies flat, and drapes naturally on a small body.
For babies especially, a seamless or minimally seamed sweater is ideal. Babies have sensitive skin, and the fewer rough seams pressing against their shoulders and underarms, the better. A round yoke also distributes the weight of the sweater evenly, which means it hangs well and doesn’t pull or bunch around the neck.
Adding lace to the yoke takes this already charming construction and elevates it into something heirloom-worthy. The leaf motif used in this pattern is classic and timeless. It works beautifully in both natural and dyed yarns, and the openwork of the lace allows a peek of color or skin underneath, making the sweater feel lighter and more delicate than a solid-knit fabric would.
Yarn and Needle Recommendations
Choosing the right yarn is half the battle when it comes to lace knitting. For a baby sweater, you want something that is soft against sensitive skin, durable enough to survive repeated washing, and smooth enough that your yarn-overs and decreases read clearly.
A fingering weight or DK weight yarn works beautifully for this pattern. Fingering weight will produce a delicate, fine fabric that shows off the lace beautifully, while DK weight creates a slightly sturdier fabric that is still lightweight and soft. Avoid fuzzy or heavily textured yarns for the lace sections — the halo of a mohair, for example, will obscure the leaf motif and all your careful work will be lost in the fluff.
Some excellent yarn options to consider include merino wool blends, cotton-merino blends (especially good for warmer climates or babies with wool sensitivity), and bamboo-cotton blends. If you prefer a machine-washable option, look for superwash merino, which maintains the softness of wool while being practical for parents who need easy care.
For needles, a set of circular needles in the appropriate size for your yarn weight will be essential. You will use a longer circular (32 to 40 inches) for the body and yoke, and either double-pointed needles or a shorter circular (16 to 24 inches) for the sleeves. Interchangeable needle sets are particularly handy for this type of project.
Gauge and Sizing
Before you cast on, please swatch. I know this is advice that knitters often skip, but gauge is especially important for a baby garment. A difference of even one stitch per inch can mean the difference between a sweater that fits a 6-month-old and one that fits a 3-year-old.
For this pattern using DK weight yarn on US size 4 (3.5mm) needles, the target gauge is approximately 22 stitches and 30 rows per 4 inches in stockinette stitch after blocking. Wash and block your swatch the same way you plan to wash the finished sweater, since many yarns — especially those with natural fiber content — bloom or relax significantly after their first wash.
This pattern is written in three sizes: 3–6 months (6–12 months, 12–18 months), with finished chest measurements of approximately 18 (20, 22) inches. These measurements include a small amount of ease, as babies grow quickly and a little extra room allows the sweater to be worn across more than one season.
Materials Needed
To knit this leaf lace baby sweater, you will need the following:
Yarn in the weight of your choice (approximately 300–400 yards for the smallest size, 400–500 yards for the medium size, and 500–600 yards for the largest size), a circular needle in US size 4 (3.5mm) in both a 32-inch length and a 16-inch length or a set of double-pointed needles for the sleeves, stitch markers (at least 6), a tapestry needle for weaving in ends, scrap yarn or stitch holders for the underarm stitches, and 3 to 5 small buttons for the back neck opening if you choose to include one.
Special Stitches and Abbreviations
Before diving into the pattern, let’s review the key abbreviations and techniques you will encounter.
k — knit
p — purl
k2tog — knit two stitches together (a right-leaning decrease)
ssk — slip, slip, knit (a left-leaning decrease)
yo — yarn over
pm — place marker
sm — slip marker
CO — cast on
BO — bind off
RS — right side
WS — wrong side
The leaf lace motif used in the yoke is built primarily from yarn-overs and paired decreases, which is the foundation of most lace knitting. Each yarn-over creates a hole (the openwork of the lace), and each decrease compensates by reducing the stitch count back to the original number. When worked in sequence over several rows, these simple maneuvers create the impression of leaves or feathers rising up the yoke.
The Leaf Lace Chart Explained
The leaf lace motif in this pattern is worked over a 12-stitch, 16-row repeat. If you are comfortable reading charts, the chart will be provided below in text format. If you prefer written instructions, both versions are included.
The basic leaf is formed by working a central knit stitch flanked by yarn-overs on either side, with decreases at the outer edges of each leaf to maintain stitch count. Over the course of 8 right-side rows, the leaf builds from a single pointed tip to a full, rounded shape, then narrows back to a point at the top. Purl rows on the wrong side are worked plain (or as indicated in the pattern) to allow the right-side motif to stand out clearly.
One of the most useful things to know about this particular motif is that it is very intuitive once you have worked the first repeat. Most knitters find that they can put the chart aside after one or two complete repeats and work the pattern from memory, which makes for pleasant, meditative knitting.
Pattern Instructions
Casting On and Working the Body
This sweater is knit from the bottom up. Begin by casting on for the back body, work the hem, then join for working in the round or continue flat as desired.
For the 6-month size (the middle size), cast on 110 stitches. For the 3–6 month size, cast on 99 stitches. For the 12–18 month size, cast on 121 stitches.
Work a ribbed hem of 1×1 rib (knit 1, purl 1) for approximately 1 inch (about 8 rows). This creates a tidy, slightly elasticized edge that lies flat and frames the body of the sweater neatly.
After the ribbing, continue in stockinette stitch (knit on right side rows, purl on wrong side rows, or knit every round if working in the round) until the body measures 6 (7, 8) inches from the cast-on edge, ending with a wrong side row or round.
At this point, set aside the underarm stitches. Place the first 6 (6, 7) stitches on a holder or scrap yarn, work across the remaining stitches until 6 (6, 7) stitches remain, and place those on a holder as well. You will now have approximately 87 (98, 107) stitches remaining for the body. Set the body aside and knit the sleeves.
Knitting the Sleeves
Cast on 33 (36, 39) stitches for each sleeve. Work 1 inch of 1×1 ribbing, then continue in stockinette stitch, increasing 1 stitch at each end of the sleeve every 6 (8, 8) rows until you have 43 (50, 55) stitches. The sleeve should measure approximately 6 (7, 8) inches from the cast-on edge when you are ready to join.
At the top of the sleeve, set aside the same number of underarm stitches as you did for the body. You will now have 31 (38, 41) stitches remaining for each sleeve.
Joining for the Yoke
This is the most exciting moment of any round yoke project: the join. Placing all of your pieces onto one needle transforms a pile of separate knitted tubes into something that immediately looks like a sweater.
Join the body and both sleeves onto your longer circular needle in the following order: back body stitches, left sleeve stitches, front body stitches, right sleeve stitches, placing markers between each section. Your total stitch count should be approximately 181 (212, 231) stitches.
Working the Yoke Decreases
The yoke requires decreasing from this joined stitch count down to approximately 60 (68, 76) stitches for the neck. This is accomplished in several decrease rounds spaced between plain knit rounds.
Work approximately 4 plain rounds in stockinette. Then work a decrease round: knit to 2 stitches before each marker, ssk, slip marker, k2tog, knit to 2 stitches before the next marker, and repeat around. This removes 8 stitches per decrease round (2 at each of the 4 markers).
Repeat this sequence — plain rounds followed by a decrease round — approximately 12 (15, 16) times total, adjusting the number of plain rounds between decreases as the yoke grows shallower.
When the yoke measures approximately 4.5 (5, 5.5) inches from the joining round, you are ready to introduce the leaf lace section.
The Leaf Lace Yoke Section
At this point in the yoke, you will have somewhere between 100 and 130 stitches on your needle, depending on your size. The leaf lace motif is worked over the final 2 to 3 inches of the yoke, just before the neckline.
Begin the lace on a right-side round. Work the 12-stitch repeat around the full circumference of the yoke, adjusting your stitch count slightly if needed to accommodate full repeats. The lace section is worked over 16 rounds total, completing one full leaf motif.
Round 1: k5, yo, k1, yo, k5, repeat from to end.
Round 2 and all even rounds: knit all stitches.
Round 3: k4, ssk, yo, k1, yo, k2tog, k4, repeat from
Round 5: k3, ssk, k1, yo, k1, yo, k1, k2tog, k3, repeat from
Round 7: k2, ssk, k2, yo, k1, yo, k2, k2tog, k2, repeat from
Round 9: k1, ssk, k3, yo, k1, yo, k3, k2tog, k1, repeat from
Round 11: ssk, k4, yo, k1, yo, k4, k2tog, repeat from
Round 13: k5, ssk, k1, k2tog, k3, repeat from
Round 15: k4, ssk, k2tog, k2, repeat from
Round 16: knit.
After the lace section, work 4 to 6 rounds of 1×1 ribbing for the neckband, then bind off loosely. A stretchy bind-off method such as the yarn-over bind-off or the Jeny’s surprisingly stretchy bind-off works beautifully here and ensures the neck opening is wide enough to fit over a baby’s head comfortably.
Finishing
Graft or seam the underarm stitches together using Kitchener stitch for a seamless join, or use a three-needle bind-off for a more structured seam. Weave in all ends carefully, making sure to secure the yarn tails from the join points, which tend to come loose if not anchored well.
Block your finished sweater by soaking it in cool water with a small amount of wool wash, gently pressing out the excess water, and laying it flat on a blocking board or clean towel. Pin the lace yoke out gently to open up the motif. Allow it to dry completely before wearing. You will be amazed at how much blocking transforms lace knitting — what looked like a slightly lumpy tangle of yarn becomes crisp, defined, and beautiful.
Caring for a Hand-Knitted Baby Sweater
A hand-knitted sweater is a labor of love, and taking good care of it ensures it can be passed down or worn through the entire season. If you used a superwash fiber, the sweater can typically be machine washed on a gentle cycle in cold water and laid flat to dry. Non-superwash wools should always be hand washed. Avoid wringing the sweater — press it gently and support the weight when moving it from the water to the drying surface to prevent stretching.
Store the sweater folded rather than hung to preserve the shape of the shoulders and yoke.
Customizing This Pattern
One of the great joys of a free pattern like this one is how easily you can make it your own. Consider working the sweater in a self-striping yarn to add color play to the body without requiring you to manage multiple yarn ends. Try adding a simple eyelet border around the hem to echo the lace on the yoke. Swap out the buttons on the back neck placket for pretty snaps or tiny fabric-covered buttons for a completely different aesthetic.
You can also experiment with sizing up the gauge to a worsted weight yarn for a slightly chunkier, warmer sweater, perfect for winter babies. Just be sure to swatch and recalculate your stitch counts accordingly.
A Note on Gifting Hand-Knitted Items
If you are knitting this sweater as a gift, consider including a small card with the fiber content and washing instructions. Parents are often unsure how to care for hand-knitted garments, and a simple note tucked into the gift removes any anxiety about ruining something so clearly made with care. You might also consider knitting it in a slightly larger size than you think is needed — babies grow fast, and a sweater that fits at 12 months will be worn far more than one sized for a newborn who outgrows it in weeks.
Hand-knitted gifts carry something that purchased items simply cannot: time, attention, and intention. Every stitch in this leaf lace pullover represents a moment you chose to create something beautiful for someone you care about. That is worth more than any price tag, and it is worth the time it takes to do it well.
Happy knitting.
