Below you will find the full free pattern, a list of materials, step-by-step instructions, helpful tips, and information about an upgraded paid PDF version if you want something polished you can print and keep.
Why Knit a Baby Blanket?
Handmade baby gifts hold a special kind of meaning. Unlike store-bought items that come off an assembly line, a knitted blanket represents hours of thought and effort. New parents often treasure these pieces for years, and many children grow up sleeping with their handmade blankets long past the infant stage.
Hearts are a particularly lovely motif for a baby blanket. They are universally understood, timeless in design, and work beautifully in a wide range of yarn weights and colors. Whether you are making this blanket for a baby shower, a new sibling, a niece or nephew, or your own child, a heart pattern carries a message that doesn’t need words.
Materials You Will Need
Before you cast on, gather everything you need so your knitting session flows smoothly from beginning to end.
Yarn: Approximately 600–800 yards of worsted weight yarn, depending on your finished size. Look for a soft, washable yarn since baby items need to survive many trips through the laundry. 100% superwash merino wool, cotton blends, and acrylic yarns labeled “baby soft” are all excellent choices. Popular options include Lion Brand Baby Soft, Paintbox Simply DK (used at a looser gauge), Cascade 220 Superwash, and Paintbox Simply Chunky for a thicker version.
Needles: US size 7 (4.5mm) straight or circular needles. Circular needles are recommended even for flat knitting because the blanket will grow quite wide and the weight is easier to manage on a cable.
Other supplies: A tapestry needle for weaving in ends, scissors, stitch markers if desired, and a ruler or measuring tape to check your gauge.
Finished dimensions: Approximately 30 inches by 36 inches for a standard baby receiving blanket. You can easily adjust the dimensions by adding or subtracting multiples of the stitch repeat (described below).
Gauge
18 stitches and 24 rows = 4 inches in stockinette stitch on US size 7 needles.
Gauge is especially important in a blanket like this because the heart motifs depend on a consistent tension to look crisp and clear. Take the time to knit a swatch before you begin, wash and block it, and measure again. Adjust your needle size as needed. Going up a needle size will give you a slightly softer, drapier fabric. Going down a size will give you tighter, more defined stitches.

The paid PDF is ideal for knitters who like to print their patterns, work from a binder, or give the pattern as a gift alongside a bundle of yarn. It is also a wonderful option for anyone who wants to teach this pattern in a class setting.
The paid PDF is available for a small one-time purchase and includes lifetime access with any future updates.
Understanding the Heart Motif
The heart in this pattern is created using a combination of knit and purl stitches on a stockinette background. On the right side of the fabric, the hearts appear in reverse stockinette (bumpy texture) against a smooth stockinette background, which makes them pop beautifully without requiring any colorwork or intarsia. This means you are working with a single color of yarn throughout — simple, elegant, and beginner-friendly.
The heart repeat is worked over 17 stitches and 16 rows. Once you memorize the chart, most knitters find they can work through it without needing to look at the instructions at all.
If you prefer colorwork, you can absolutely adapt this pattern to use two colors. Simply knit the background in your main color and work the heart stitches in your contrast color using basic stranded colorwork or intarsia techniques. Instructions for both adaptations are included in the paid PDF.

The Heart Baby Blanket Pattern
Cast On
Using your preferred cast on method, CO 135 stitches. A long-tail cast on is recommended for its elasticity and clean edge. If you would like a wider blanket, add 17 stitches (one full heart repeat) or a multiple thereof. For a smaller blanket such as a preemie size, subtract 17 stitches.
Border Setup
Rows 1–8: Knit every stitch (garter stitch border). This creates a firm, non-curling edge at the bottom of your blanket.
After completing 8 rows of garter stitch, you are ready to begin the main body.
Main Body
The blanket body is worked in a combination of stockinette and the heart motif panels. The layout is as follows: 8 stitches of garter border on each side (knit every row), with the heart panel worked in the center.
Row Setup for Main Body:
Every RS row: K8 (border), work Heart Pattern across center stitches, K8 (border).
Every WS row: K8 (border), P to last 8 sts, K8 (border).
This gives you a clean knit border on both sides that matches your top and bottom garter stitch edges.
The Heart Motif Chart (Written Instructions)
The heart is worked over a multiple of 17 stitches plus 2 edge stitches. The blanket center contains 119 stitches (seven heart repeats of 17 stitches each). The following chart rows describe one complete heart.
For each row below, the instructions describe what to do across one 17-stitch repeat. Repeat these instructions across all 7 repeats.
Row 1 (RS): K17
Row 2 (WS): P17
Row 3 (RS): K7, P1, K1, P1, K7
Row 4 (WS): P6, K1, P3, K1, P6
Row 5 (RS): K5, P2, K5, P2, K3
Row 6 (WS): P4, K2, P5, K2, P4 (Note: adjust spacing per repeat — see note below)
Row 7 (RS): K3, P3, K5, P3, K3
Row 8 (WS): P3, K3, P5, K3, P3
Row 9 (RS): K2, P4, K5, P4, K2
Row 10 (WS): P2, K4, P5, K4, P2
Row 11 (RS): K2, P4, K5, P4, K2
Row 12 (WS): P3, K3, P5, K3, P3
Row 13 (RS): K4, P2, K5, P2, K4
Row 14 (WS): P5, K1, P5, K1, P5
Row 15 (RS): K6, P1, K3, P1, K6
Row 16 (WS): P8, K1, P8
A note on Row 6: The purl clusters that form the top lobes of the heart are slightly offset from each other. In the written pattern, work as follows — K5, P2, K3, P2, K5 for a cleaner lobe definition. The paid PDF includes a visual chart that makes this immediately clear.
After completing Row 16, you have finished one full heart repeat vertically. Continue repeating Rows 1–16 until your blanket measures approximately 34 inches from the cast-on edge, ending with Row 16 of a complete heart repeat.
Finishing the Blanket
Top Border
Work 8 rows of garter stitch (knit every row) across all stitches, mirroring the bottom border.
Bind Off
BO all stitches loosely on a RS row using a standard bind off or a stretchy bind off method. A stretchy bind off such as the k2tog bind off ensures the top edge has the same give as the rest of the blanket, which is especially important if you plan to wash and block it frequently.
Weaving In Ends
Thread your tapestry needle and weave in all ends on the WS of the blanket, going in two different directions for security. Baby items get a lot of washing, and securely woven ends will hold up much better over time.
Blocking Your Blanket
Blocking is the step many knitters skip, but for a textured pattern like this one, it makes a dramatic difference. Hearts that look slightly uneven or unclear before blocking often pop beautifully after a soak and a gentle stretch.
To wet block your blanket, fill a basin or your bathtub with cool water and a small amount of wool wash. Submerge the blanket and let it soak for 15–20 minutes. Do not agitate it — just let the water penetrate the fibers. Gently lift the blanket out (it will be heavy) and press out the water. Do not wring. Lay it flat on a clean towel, roll the towel up to absorb more water, then unroll and transfer the blanket to a blocking mat or another flat surface. Smooth it into shape, pin if needed, and let it dry completely, which may take 24–48 hours depending on your yarn.
For acrylic yarn, wet blocking has minimal effect. Instead, use the “killing” method: pin the blanket to your blocking mat and hover a steam iron several inches above the surface, allowing the steam to penetrate without the iron ever touching the fabric. This relaxes acrylic fibers and gives you a similar result.
Color Suggestions and Variations
One of the best things about this pattern is how well it adapts to color choices. Here are a few combinations that work beautifully:
A classic soft white or cream gives the hearts a delicate, heirloom quality. Pair this with a white or wooden button closure on a matching hat for a coordinated gift set.
Pale pink with the hearts worked in a slightly deeper rose creates a subtle tonal effect that is elegant rather than sugary sweet.
A variegated yarn in blues and grays makes the hearts appear and disappear in a dreamy, almost magical way — no two hearts look exactly the same.
Soft sage green is a popular gender-neutral choice that feels fresh and modern.
If you are feeling adventurous, consider a two-color version with a cream background and butter yellow hearts. This requires a basic understanding of colorwork or intarsia, both of which are covered in the paid PDF with step-by-step guidance.
Sizing Adjustments
Preemie size: CO 84 stitches (5 heart repeats plus borders). Finished dimensions approximately 18 by 22 inches.
Standard baby size (as written): CO 135 stitches (7 heart repeats plus borders). Finished dimensions approximately 30 by 36 inches.
Toddler size: CO 186 stitches (10 heart repeats plus borders). Finished dimensions approximately 40 by 48 inches.
For any size, simply maintain the 8-stitch garter borders on each side and fill the center with as many 17-stitch heart repeats as needed for your desired width.
Tips for Beginner Knitters
If you are newer to knitting and this is your first project with a textured motif, here are a few things that will help.
Read through the entire pattern before you cast on. Even if you do not understand every step yet, getting a sense of the overall structure makes each section feel more intuitive when you arrive at it.
Use a row counter. The 16-row heart repeat is easy to lose track of, especially if you knit in short sessions. A simple mechanical counter or a note on your phone works perfectly.
Mark your right side. Place a small locking stitch marker on the right side of the work when you cast on. Knowing which side is which will help you orient yourself quickly, especially after setting your project down between sessions.
Tension matters. Try to maintain even tension throughout. If you find your purl stitches are much looser than your knit stitches (a common challenge), try purling through the back loop or switching to a Continental knitting style for the purl rows.
Count your stitches frequently. After every heart row, do a quick count to make sure you still have the right number. Catching a mistake on Row 5 is far easier than unraveling from Row 12.
Gifting This Blanket
A handknit baby blanket is one of the most treasured gifts a new parent can receive. To make your gift feel extra special, consider these finishing touches. Wash and block the finished blanket before wrapping it so it arrives looking its very best. Fold it neatly and tie it with a ribbon or wrap it in tissue paper. Include a small handwritten card that explains it was made by hand, with what yarn, and with how much love. Many parents frame these cards or keep them with the blanket for years.
If you are making blankets to donate to a NICU, shelter, or charitable organization, this pattern scales well for group knitting events and uses materials that are both affordable and easy to source.

Final Thoughts
Knitting a heart baby blanket is one of those projects that gives back as much as you put into it. The process is meditative and enjoyable, the result is genuinely beautiful, and the meaning behind it — a small, soft thing made stitch by stitch for someone who hasn’t even arrived yet — is something store shelves simply cannot replicate.
Whether you are knitting this for a baby shower gift, a hospital donation, a grandchild, or just because the pattern called to you, take your time, enjoy the rhythm of it, and know that you are making something that will be loved.
Happy knitting.
