How to Knit a Baby Blanket with Bobbles
There is something deeply satisfying about knitting a baby blanket. It is small enough to finish in a reasonable amount of time, useful enough to be treasured for years, and personal enough to feel like a genuine gift of love. Add bobbles into the mix and you have a blanket that transforms from a simple rectangle of fabric into something textured, playful, and visually interesting — the kind of heirloom piece that gets passed down and talked about.
This guide walks you through everything you need to know to knit a baby blanket with bobbles, from choosing your yarn and needles all the way to weaving in your last end and blocking your finished piece. Whether you are a beginner who has just learned how to cast on or an intermediate knitter looking for a satisfying weekend project, this pattern and its explanations are written with you in mind.
What You Will Need Before You Start
Before you pick up your needles, it helps to gather everything you need in one place. Stopping mid-project to hunt for a tapestry needle or realize you are three balls of yarn short is the kind of interruption that takes the joy right out of knitting.
Yarn: Choose a yarn that is soft, washable, and durable. Baby skin is sensitive, and a blanket that cannot survive a washing machine is going to make new parents very unhappy very quickly. A worsted weight yarn in a merino wool, cotton, or an acrylic blend labeled “machine washable” is ideal. You will need approximately 800 to 1,000 yards depending on your finished size. Lion Brand Pound of Love, Paintbox Simply DK (held double), and Cascade 220 Superwash are all excellent choices.
Needles: For a worsted weight yarn, US size 7 or 8 (4.5 mm to 5 mm) circular needles work beautifully. You do not have to knit in the round — using circular needles for a flat project just means you are not fighting the weight of the blanket on straight needles. A 32-inch cord length gives you plenty of room.
Notions: You will need a tapestry needle for weaving in ends, stitch markers to help you keep track of the bobble placement, scissors, and a measuring tape. If you are using a yarn with a lot of stretch, a few locking stitch markers can also help you count rows.
Gauge: For this pattern, aim for approximately 18 stitches and 24 rows over 4 inches in stockinette stitch. Gauge matters more than you might expect with a blanket because even a small discrepancy multiplied across 100 or more stitches will significantly change your finished dimensions. Knit a swatch before you start.
Understanding the Bobble Stitch
The bobble is one of knitting’s most delightful tricks. It creates a small, rounded bump on the surface of your fabric by working multiple stitches into a single stitch, then collapsing them back down into one. The result is a satisfying three-dimensional texture that babies often love to feel with their hands.
There are several ways to make a bobble, and the size of the finished bump depends on how many times you increase into the base stitch before working the decrease. For a baby blanket, a five-stitch bobble is the most common and creates a cheerful, noticeable bump without being so large that it becomes uncomfortable against soft skin.
Here is how to make a five-stitch bobble, which will be abbreviated as MB (Make Bobble) throughout this pattern:
Working into the same stitch, knit into the front of the stitch but do not drop it from the left needle. Bring the yarn to the front and purl into the same stitch, then bring the yarn to the back and knit into the same stitch again, then purl once more, then knit one final time. You now have five stitches where there was originally one. Turn your work so the wrong side faces you and purl those five stitches. Turn your work again so the right side faces you and knit those five stitches. Turn once more and purl two together, purl one, purl two together — you now have three stitches. Turn and knit three together. You have your bobble. If you like, use the tip of your needle or your thumb to push the bobble toward the right side of the fabric.
This sounds more complicated than it is in practice. After you have worked your first two or three bobbles, the technique becomes almost automatic and you will find yourself moving through them quickly.
A simpler variation for beginners is the three-stitch bobble: knit into the front and back of the stitch twice, then knit into the front once more (five stitches), then pass the second, third, fourth, and fifth stitches over the first stitch one at a time. This creates a smaller, flatter bobble and involves no turning of the work, which many people find easier when they are learning.
The Pattern: Classic Bobble Baby Blanket
This pattern produces a blanket approximately 30 by 36 inches when completed in worsted weight yarn at the gauge noted above. This is a good finished size for a baby blanket — large enough to be genuinely useful but small enough to knit in a reasonable timeframe.
Abbreviations used:
CO — cast on, K — knit, P — purl, MB — make bobble (as described above), rep — repeat, RS — right side, WS — wrong side, sts — stitches, sl — slip
Casting On
Using a long-tail cast on, cast on 135 stitches. The long-tail cast on is recommended here because it creates a neat, elastic edge that will look beautiful alongside your finished border. If you are not familiar with the long-tail cast on, a simple knitted cast on works just as well.
Border Setup
For the first six rows, knit every stitch on every row. This creates a garter stitch border at the bottom of your blanket that will keep the edge from curling and give it a clean, tidy finish. On a blanket like this, an unworked garter border is one of the small details that makes the difference between a blanket that looks homemade and one that looks truly well-crafted.
Main Body
Once your six rows of garter border are complete, you will begin the main body of the blanket, which combines a simple stockinette background with a repeating bobble motif. The border stitches on either side are maintained throughout by slipping the first stitch of every row purlwise and knitting the last three stitches of every row. This gives you a tidy slipped-stitch edge on both sides.
Row 1 (RS): Sl1, K3, knit to last 4 sts, K4.
Row 2 (WS): Sl1, K3, purl to last 4 sts, K4.
Rows 3–6: Repeat Rows 1 and 2 twice more.
Row 7 (Bobble Row, RS): Sl1, K3, K5, MB, K9; rep from to last 9 sts, MB, K4, K4.
Adjust the spacing slightly if needed to ensure your bobbles land symmetrically based on your stitch count. The pattern as written is designed for 135 stitches with the border stitches accounted for, placing your bobbles with 9 knit stitches between each one and centering the row.
Row 8 (WS): Sl1, K3, purl to last 4 sts, K4.
Rows 9–18: Continue in stockinette with border stitches maintained.
Row 19 (Bobble Row, RS): Sl1, K3, K10, MB, K9; rep from to last 14 sts, MB, K10, K4.
This second bobble row offsets the bobbles from the first, creating a staggered grid pattern across the blanket. The visual effect is charming — organized enough to look intentional, playful enough to feel fun.
Row 20 (WS): Sl1, K3, purl to last 4 sts, K4.
Continue repeating this 20-row sequence — six plain stockinette rows followed by a bobble row, then nine more plain rows followed by a staggered bobble row — until your blanket measures approximately 30 inches from the cast-on edge, ending after a wrong-side row.
Top Border
Work six rows of garter stitch across all stitches, mirroring your cast-on border. Then bind off loosely in knit. A loose bind-off matters here; if you bind off too tightly, the top edge of your blanket will pucker and the blanket will never lie flat, even after blocking. If you tend to bind off tightly, go up a needle size for the bind-off row.
Tips for Getting Beautiful Bobbles
Knitters often run into a few common bobble problems. Here is how to head them off before they happen.
Tension control: Bobbles worked too tightly will pucker the surrounding fabric. Work the increases and the bobble rows a bit more loosely than you think you need to, and the finished texture will be smoother and more even.
Pushing the bobble to the right side: After you finish each bobble, use your right needle tip, a cable needle, or your thumb to push the bobble firmly toward the right side of the fabric before continuing to the next stitch. If you do not do this while the yarn is still pliable, the bobble has a tendency to sink to the wrong side, especially in a pattern where the wrong side is facing you as you work the bobble decrease rows.
Yarn ends: Some knitters like to leave a small tail and weave it in as they go, but for a baby blanket it is worth being meticulous about weaving in every bobble end securely when you finish. Baby blankets go through a lot of washing, and a bobble that has not been properly secured can eventually pull loose.
Counting rows: Keep a row counter or a simple tally in a notebook. When you are working a 20-row repeat across a blanket that will require many repeats, losing track of which row you are on is easy to do and hard to diagnose after the fact.
Choosing Your Color Palette
One of the great joys of this pattern is how dramatically it changes depending on the yarn you choose. A single solid color — particularly a soft white, cream, or pale gray — makes the bobble texture the star of the show. The light catches the raised bumps and creates beautiful shadows across the surface of the blanket, especially in natural light.
A tonal or semi-solid yarn (one that varies within the same color family) adds depth and interest without distracting from the texture. Think dusty blue, heathered lavender, or a warm oatmeal tone.
If you prefer more color, consider a stripe pattern: work the main body in a neutral background color and switch to a coordinating accent color for the bobble rows. This requires managing more ends but creates a genuinely striking result. Pastel pinks and creams, navy and white, or sage green and cream are all combinations that work beautifully.
Avoid heavily variegated yarns with many colors changing over short distances. These yarns tend to visually camouflage textured stitches like bobbles, which means you put in all that extra work and the beautiful texture disappears into the color chaos.
Blocking Your Finished Blanket
Blocking transforms a finished knitted piece from something that looks like a project into something that looks like a heirloom. For a baby blanket, wet blocking is the most effective method and takes very little effort.
Fill a clean sink or basin with cool water and a small amount of gentle wool wash or baby shampoo. Submerge your blanket completely and gently press the water through the fabric without agitating it. Let it soak for about 20 minutes, then gently squeeze out the water — do not wring or twist — and roll the blanket in a clean dry towel to absorb most of the moisture.
Lay the blanket flat on a blocking mat or clean towels on the floor. Use rust-proof T-pins to pin the blanket to its finished dimensions, smoothing the edges and squaring the corners. Make sure each bobble is sitting right-side-out and the fabric is evenly stretched. Let it dry completely, which typically takes 24 to 48 hours depending on the humidity in your home.
When you unpin a blocked baby blanket, the transformation is genuinely satisfying. The stitches even out, the edges lie flat, the bobbles plump up, and the whole piece takes on the polished quality of something made with care and skill.
Caring for a Knitted Baby Blanket
Part of making this gift is making sure it lasts. Include a small care card with your blanket that tells the new parents how to wash it properly. If you used a superwash wool or an acrylic blend, the blanket is machine washable on a gentle cycle in cool water. If you used a non-superwash wool, it will need hand washing.
In either case, recommend air drying flat rather than tumble drying, as the heat from a dryer can cause even superwash wool to felt over time, and high heat shortens the life of acrylic fibers as well. A blanket that is treated gently will look beautiful for years.
Making It Your Own
Once you are comfortable with this pattern, there are many ways to adapt and personalize it. You can increase the density of your bobbles by spacing them eight stitches apart instead of ten. You can add a simple lace border, such as a row of yarn-overs and k2tog repeats, along the edges for a more delicate look. You can knit two strands of a fingering weight yarn held together for a fabric with a slightly different drape and texture. You can work the bobbles in a contrasting color for a bold, graphic effect.
Some knitters add the baby’s initials in duplicate stitch after the blanket is finished, which is a beautiful personal touch that requires no modification to the knitting itself. Others add a narrow crochet border in a complementary color to frame the finished piece.
The structure of this pattern is simple and forgiving enough that it welcomes experimentation. Once you have knitted it once, you will find yourself thinking of variations naturally.
A Few Final Thoughts
There is a long tradition behind handmade baby gifts. In a world where it is easy to click a button and have something arrive at a door, the time and intention that go into a hand-knitted blanket are noticed. New parents understand, even if they cannot fully articulate it, that this gift took hours and was made specifically for their child.
A baby blanket with bobbles is not a complicated project, but it is a rich one. The texture rewards close attention. The repetition is meditative. The finished object is genuinely beautiful. Whether you are making this for someone you love or exploring a new technique for the pleasure of learning it, you are in for a satisfying and worthwhile knit.
Cast on, count your stitches, work your first bobble, and enjoy every row.
