Heart Baby Blanket – Free Knitting Pattern
There is something deeply satisfying about knitting a blanket for a baby. It is one of those projects that feels purposeful from the very first cast-on, and by the time you bind off the last stitch, you have created something genuinely meaningful — a soft, handmade object that will wrap around a new life and, with any luck, be loved nearly to pieces over the years. This heart baby blanket pattern is one of my absolute favorites to recommend to knitters of all levels. The textured heart motif is created entirely through knit and purl stitches, so there is no colorwork, no complicated cables, and no tricky techniques to master. If you can knit and purl, you can make this blanket.
Whether you are knitting this as a gift for a baby shower, a personal project for your own little one, or simply because you have a ball of soft yarn and an afternoon to spare, this pattern will walk you through every step. I have included notes on yarn substitutions, needle size guidance, tension tips, and care instructions so that you have everything you need in one place.
Let’s get started.
About This Pattern
This heart baby blanket uses a repeating textured heart motif worked in a simple knit-and-purl combination. The hearts appear raised against a reverse stockinette background, giving the blanket a lovely dimensional quality that looks far more complex than it actually is. The border is worked in seed stitch on all four sides, which keeps the edges from curling — a common frustration with blankets worked in stockinette.
The finished blanket measures approximately 30 inches by 36 inches, which is a generous size for a newborn and works well through the first year. You can easily scale this up or down by adjusting the number of pattern repeats, and I have included notes on how to do that at the end of the pattern.

Choosing Your Yarn
The yarn you choose will make a significant difference in how this blanket turns out, and more importantly, how it feels against a baby’s skin. Babies have sensitive skin, so softness is the top priority. Here are some excellent options to consider.
Superwash Merino Wool is the gold standard for baby knits. It is naturally soft, temperature-regulating, and beautifully elastic, which means it will stretch with your knitting and then recover its shape. The superwash treatment makes it machine washable, which is a practical necessity for anything going near a baby. Look for yarn with a DK or light worsted weight to hit gauge without too much trouble.
Cotton and Cotton Blends are another excellent choice, particularly for warmer climates or spring and summer babies. Cotton has a lovely drape and is easy to wash. It is slightly less forgiving than wool in terms of elasticity, so your tension will need to be fairly consistent, but it produces a beautifully crisp stitch definition that makes the heart motifs pop.
Acrylic Blends have come a long way in terms of softness, and a high-quality acrylic specifically labeled as “baby soft” or “anti-pilling” can work beautifully. The main advantage is durability and ease of care — acrylic is virtually indestructible and can handle repeated washing without losing its shape or color. For a gift blanket that will see heavy use, this is often the most practical choice.
Whatever fiber you choose, do a quick scratch test on the inside of your wrist before buying. If it feels rough or itchy to you, it will feel the same to a baby, whose skin is far more sensitive. When in doubt, go softer.
Notes Before You Begin
Seed Stitch Border: The first and last 5 stitches of every row, as well as the first and last 5 rows of the blanket, are worked in seed stitch. Seed stitch is worked by alternating knit and purl stitches, and then on the following row, purling the knit stitches and knitting the purl stitches. This creates a firm, flat border that keeps the blanket from curling.
Reading the Chart: The heart motif can be worked either from the written instructions below or from the chart provided. Each square on the chart represents one stitch. Right-side rows are read from right to left, and wrong-side rows are read from left to right.
Stitch Markers: Place stitch markers after your first 5 border stitches and before your last 5 border stitches to help you track where the border ends and the pattern begins. This small habit will save you a great deal of counting as the blanket grows.
Tension: Try to keep your tension even throughout, particularly when transitioning between knit and purl stitches. If you find your tension tightening around the purl stitches — which is common — try consciously relaxing your hands as you work, or try going up half a needle size.

Pattern Instructions
Cast On
Using a long-tail cast on or your preferred method, CO 135 stitches. The long-tail cast on is recommended here because it creates a firm, neat edge that mirrors the look of a bound-off edge, giving the finished blanket a tidy, professional appearance.
Seed Stitch Border Setup (Rows 1–5)
Work 5 rows of seed stitch across all stitches to create the bottom border.
Row 1 (RS): K1, p1; rep from to last st, k1.
Row 2 (WS): K1, p1; rep from to last st, k1.
Repeat these two rows for a total of 5 rows.
Begin Heart Motif Section
After completing the 5 seed stitch rows, you will begin the main body of the blanket. On every row, the first 5 stitches and the last 5 stitches are always worked in seed stitch as established. The heart motifs fill the center 125 stitches.
The heart motif is worked over a 25-stitch, 24-row repeat. You will have 5 complete hearts across the width of the blanket. The motif repeat is given below in full.
Heart Motif (25 stitches, 24 rows)
Row 1 (RS): K across all 25 sts.
Row 2 (WS): P across all 25 sts.
Row 3 (RS): K11, p3, k11.
Row 4 (WS): P10, k5, p10.
Row 5 (RS): K9, p3, k1, p3, k9.
Row 6 (WS): P8, k3, p3, k3, p8.
Row 7 (RS): K7, p3, k5, p3, k7.
Row 8 (WS): P6, k3, p7, k3, p6.
Row 9 (RS): K5, p3, k9, p3, k5.
Row 10 (WS): P5, k2, p11, k2, p5.
Row 11 (RS): K5, p2, k11, p2, k5.
Row 12 (WS): P5, k2, p11, k2, p5.
Row 13 (RS): K6, p1, k11, p1, k6.
Row 14 (WS): P7, k9, p9. (Note: this row narrows the heart toward the point)
Row 15 (RS): K8, p7, k10.
Row 16 (WS): P10, k5, p10.
Row 17 (RS): K11, p3, k11.
Row 18 (WS): P12, k1, p12.
Row 19 (RS): K across.
Row 20 (WS): P across.
Row 21 (RS): K across.
Row 22 (WS): P across.
Row 23 (RS): K across.
Row 24 (WS): P across.
This completes one full heart motif repeat. Work this 24-row repeat across all 5 heart motif sections simultaneously, working the border stitches in seed stitch on each row.
Full Pattern Row Instructions (with Border)
For every right-side row:
Work 5 sts in seed stitch as established, sm, work heart motif row across the 125 center stitches, sm, work 5 sts in seed stitch as established.
For every wrong-side row:
Work 5 sts in seed stitch as established, sm, work the corresponding WS heart motif row across the 125 center stitches, sm, work 5 sts in seed stitch as established.
Continue working the 24-row heart motif repeat until the blanket measures approximately 34.5 inches from the cast-on edge, ending after completing a Row 24 (or Row 6, 12, 18, or 24 of the repeat — any RS-ready row will work as a stopping point before the top border).
Top Seed Stitch Border (Rows final 5)
Work 5 rows of seed stitch across all 135 stitches, exactly as you did for the bottom border.
Bind Off
Bind off all stitches loosely in seed stitch pattern. Using a needle one or two sizes larger for the bind-off will help keep the edge from puckering.
Finishing
Weave in all ends securely using a tapestry needle. Weave each tail in at least two different directions to prevent them from working loose with washing. Trim any excess yarn close to the fabric, being careful not to cut the knitting itself.
Blocking is highly recommended and makes a noticeable difference in the finished look of this blanket. Even if you are using acrylic yarn, blocking will help even out your tension and allow the heart motifs to open up beautifully. For wool, wet blocking works best: soak the blanket in cool water for 20–30 minutes, gently squeeze out the excess water without wringing, and lay it flat on a blocking mat or clean towel. Pin it to your desired dimensions and allow it to dry completely before unpinning. For acrylic, you can use steam blocking: hold a steam iron slightly above the surface of the blanket and allow the steam to penetrate without pressing down. Then leave it to dry flat.
Sizing Adjustments
One of the joys of a pattern like this is how easy it is to scale. Because the heart motif is worked over a 25-stitch repeat, you can add or subtract repeats in multiples of 25 stitches to change the width. For every repeat you add, plan on approximately 180–220 additional yards of yarn.
For a crib-sized blanket, consider casting on 185 stitches for 7 heart motifs across, and working until the blanket measures approximately 45 inches. This will give you a blanket suitable for a standard crib mattress.
For a smaller stroller or car seat blanket, casting on 85 stitches for 3 heart motifs works beautifully, and the blanket works up quickly enough to be a last-minute gift.
Care Instructions
Because babies are messy and blankets spend a lot of time being washed, it is worth taking care to choose a yarn you can launder easily. Whatever fiber you use, here are some general guidelines.
For superwash wool, machine wash on a gentle or delicate cycle in cold water and lay flat to dry. Avoid high heat, which can felt even superwash wool over time.
For cotton, machine wash warm or cold and tumble dry on low. Cotton is the most durable and heat-tolerant of the natural fibers, so it can handle a bit more in the laundry.
For acrylic, machine wash and tumble dry on low. Avoid high heat, which can distort acrylic fibers permanently.
Always check the yarn label for specific care instructions, as different brands and fiber blends will have different recommendations.
Gifting This Blanket
This heart baby blanket makes an extraordinary gift, and a few small touches can make it even more special. Consider adding a handwritten card with the care instructions and a note about the yarn you used — many parents appreciate knowing what went into something handmade. If you know the baby’s name, you can embroider it in simple stem stitch along the bottom border using a coordinating or contrasting color of yarn. You might also tuck in a skein of the yarn you used so the recipient has it on hand for any repairs down the line.
Presenting the blanket folded and tied with a ribbon in a coordinating color, or wrapped around a small stuffed animal, makes for a beautiful presentation at a baby shower. Handmade gifts carry a meaning that no store-bought item can replicate, and a knitted blanket — especially one that has taken real time, thought, and care to complete — is something many families hold onto for years.
A Few Final Tips for Success
If you are newer to knitting, take your time with the transition between the border stitches and the motif section. It is easy to slip into automatic knitting and forget you are switching from seed stitch to the charted pattern. The stitch markers will help enormously here.
Count your stitches at the end of every right-side row for the first several pattern repeats. This takes just a moment and will catch any mistakes before they turn into a problem that requires significant frogging.
If you find the pattern starting to look inconsistent — hearts that are lopsided, or stitches that do not seem to be forming shapes — stop and compare your work to the chart. Usually the issue is a single missed purl or knit that crept in a few rows back and can be corrected with a crochet hook without having to rip anything out.
Most of all, enjoy the process. Knitting a baby blanket is one of those rare projects that feels genuinely worthwhile at every stage. The yarn feels lovely in your hands, the pattern is engaging without being stressful, and the result is something you will be proud to give or to keep. Every stitch is a small act of love, and the finished object carries that with it in a way that is hard to put into words.
Happy knitting.
