Free Easy Seed Stitch Baby Blanket Knitting Pattern

There is something deeply satisfying about knitting a baby blanket. It is one of those projects that feels meaningful from the very first cast-on, and by the time you bind off the last stitch, you have made something that will wrap a tiny person in warmth and love. If you are looking for a pattern that is beginner-friendly, quick to memorize, and results in a beautifully textured finished piece, this free easy seed stitch baby blanket knitting pattern is exactly what you need.

Seed stitch is one of the most beloved textures in all of knitting. It creates a bumpy, dotted surface that lies flat, drapes beautifully, and looks far more impressive than the effort it actually requires. Unlike stockinette, which curls at the edges and often requires a border to keep it tidy, seed stitch behaves itself perfectly on its own. That makes it ideal for a baby blanket, where you want a finished, polished look without having to pick up and add stitches along every edge.

Whether you are a brand-new knitter working on your second or third project, or a seasoned maker looking for a mindless TV-friendly blanket, this pattern has something for you. Let’s dive in.

Why Seed Stitch Is Perfect for a Baby Blanket

Before we get to the actual pattern, it is worth taking a moment to understand why seed stitch works so beautifully for baby blankets specifically.

First, it lies completely flat. Because seed stitch alternates knit and purl stitches in a checkerboard pattern, the tension from each stitch counteracts its neighbor, keeping the fabric from rolling or curling. No blocking required, no border necessary — the blanket simply lies flat straight off the needles.

Second, the texture is soft and interesting on both sides. Seed stitch looks nearly identical on the front and the back, which means your blanket is fully reversible. This is a huge bonus for a baby blanket that will be flipped, tucked, and tossed around constantly.

Third, seed stitch is easy to memorize. Once you understand the rhythm — knit the purls, purl the knits — you will not need to look at the pattern again. This makes it a wonderful project to bring to a waiting room, a knitting group, or your couch on a movie night.

Finally, it works up beautifully in a wide range of yarn weights. You can use a chunky yarn for a quick, cozy blanket or a fingering weight for a delicate heirloom piece. The seed stitch texture shines in both.

Materials You Will Need

For this pattern, we are working with a medium worsted weight yarn, which is the most common and easiest to find. This creates a classic baby blanket that is neither too bulky nor too thin.

Yarn: Approximately 600 to 800 yards of worsted weight yarn (CYCA #4). Choose a soft, washable yarn designed for babies or sensitive skin. Lion Brand Baby Soft, Paintbox Simply DK (held double), Cascade 220 Superwash, or any soft 100% merino are all excellent choices. Avoid anything scratchy or that is not machine washable — parents of newborns will thank you.

Needles: US size 7 (4.5mm) straight or circular needles. Using circular needles even for a flat piece is recommended because a baby blanket has a lot of stitches and circular needles give you more room to hold them all comfortably.

Notions: A tapestry needle for weaving in ends, scissors, and stitch markers (optional but helpful).

Gauge: Approximately 18 stitches and 28 rows = 4 inches in seed stitch. Gauge is not critical for a blanket, but it will affect your finished size. If you knit loosely, your blanket will be larger; if you knit tightly, it will be smaller. Adjust needle size accordingly.

Finished Size: Approximately 30 inches by 36 inches, which is a generous receiving blanket size.

Understanding Seed Stitch

Seed stitch is worked by alternating knit and purl stitches across every row, and by making sure that you knit the stitches that appear as purls from the previous row, and purl the stitches that appear as knits. This is actually easier to do by looking at your work than by memorizing a rule.

Here is the stitch pattern for an odd number of stitches (which is what this pattern uses):

Row 1: K1, P1 repeat across to last stitch, K1.

Row 2: K1, P1 repeat across to last stitch, K1.

That is it. Because you have an odd number of stitches, every row begins and ends with a knit stitch, and the pattern automatically stacks the knits on top of purls and purls on top of knits. If you are a beginner, using an odd stitch count is the easiest way to work seed stitch without thinking too hard about it.

If you prefer to work with an even number of stitches, the rows alternate:

Row 1: K1, P1 repeat across.

Row 2: P1, K1 repeat across.

Both methods produce identical fabric. Use whichever feels more intuitive to you.

The Pattern

Cast On

Using your US 7 (4.5mm) needles and your chosen yarn, cast on 135 stitches using a long-tail cast on. The long-tail cast on creates a neat, stretchy edge that complements the seed stitch beautifully and gives your blanket a tidy bottom edge right from the start. If you are not familiar with the long-tail cast on, a simple backward loop or knitted cast on works fine too.

Body of the Blanket

All Rows: K1, P1, K1 repeat from * to end of row.

Work this row over and over until your blanket measures approximately 36 inches from the cast-on edge, or until you reach your desired length. With worsted weight yarn at the gauge noted above, this will take roughly 250 to 260 rows.

That is the entire pattern. Every single row is identical. You cast on, you work the seed stitch row repeatedly, and you bind off. No shaping, no increases or decreases, no complicated stitch counts to track.

Bind Off

Bind off loosely in pattern on a right-side row. To bind off in pattern, work each stitch as you would if you were knitting the row normally (knit the knits, purl the purls) and pass the previous stitch over as usual. Binding off in pattern keeps the edge stretchy and consistent with the rest of the blanket.

If you find your bind-off tends to be too tight, go up one needle size for the bind-off row only.

Finishing

Weave in both ends securely using your tapestry needle. Because seed stitch is a dense fabric, your ends will stay in beautifully. Weave through several stitches in one direction, then double back for a few stitches to lock the end in place.

If you want, you can wet block the finished blanket by soaking it in cool water, pressing out the excess water gently with a towel, and laying it flat to dry. Blocking will even out your tension and open up the texture slightly, giving the blanket a more polished finish. That said, seed stitch looks lovely even without blocking, so this step is completely optional.

Tips for Knitting This Blanket Successfully

Choose your yarn carefully. This is probably the most important decision you will make for this project. Baby skin is delicate, and even yarn that feels soft to your hands may be scratchy on a newborn. Look for yarns labeled “ultra soft,” “baby,” or “merino,” and choose machine-washable options whenever possible. A beautiful blanket that has to be hand-washed is a lovely thought, but most new parents will reach for the easy-care version every time.

Use stitch markers to keep track of your place. Even though every row is identical, it is easy to lose count when you are watching television or chatting. Place a marker every 25 or 30 stitches to help you spot counting errors before they travel too far.

Measure regularly. Check your length every few inches so you are not surprised by how quickly (or slowly) the blanket is growing. It is easy to either stop too early because you are eager to be done or knit past your target because you are on a roll.

Try a swatch. If you want your finished blanket to match the stated dimensions, take ten minutes to swatch before you start. Cast on 25 stitches and work seed stitch for about 25 rows, then measure. This tiny investment of time will save you from running out of yarn or ending up with a blanket that is much smaller or larger than expected.

Join new yarn at the edge. When you need to add a new skein, do so at the beginning or end of a row rather than in the middle. This keeps your joins invisible and your weaving-in simple.

Relax your tension. Seed stitch can sometimes draw in slightly because of all the knit-purl transitions. If you notice your fabric feels stiff or the stitches are hard to work, try consciously relaxing your grip or going up a needle size.

Customizing This Pattern

One of the wonderful things about a seed stitch baby blanket is how easy it is to customize without altering the basic pattern at all.

Change the size. To make a smaller stroller or car seat blanket, cast on 91 stitches and work to about 24 inches. For a larger crib blanket, cast on 181 stitches and work to about 48 inches. Just make sure your stitch count is odd so the seed stitch pattern lines up automatically.

Change the yarn weight. You can knit this pattern in almost any yarn weight by adjusting your needle size and stitch count. For a bulky yarn on US 10 or 11 needles, you might cast on 61 to 71 stitches and have a finished blanket in just a few days. For a fingering weight yarn on US 2 or 3 needles, you will have a delicate, lacier result that takes considerably longer but is absolutely stunning.

Add a color stripe. Because every row is the same, it is incredibly easy to add color stripes. Simply change yarn colors every 10 or 20 rows for a modern striped look. Carry the unused yarn up the side edge if you are alternating between just two colors.

Add a simple border. If you want a slightly more polished look, work the first and last 5 stitches of every row in garter stitch (knit every stitch) and work the first and last 5 rows in garter stitch as well. This creates a tidy frame around the seed stitch center. Just remember to add those extra stitches to your cast-on count.

Use a variegated or self-striping yarn. Seed stitch texture showcases color changes beautifully. A tonal or hand-dyed yarn will give your blanket a painterly, artistic look with no extra effort on your part.

Yarn Suggestions for This Pattern

Finding the right yarn can feel overwhelming with so many options available, so here are a few specific recommendations across different price points.

For a budget-friendly option, Lion Brand Pound of Love and Red Heart Soft are both widely available, machine washable, and come in a huge range of colors. They are not the most luxurious yarns, but they wash beautifully and hold up to heavy use.

For a mid-range option, Paintbox Simply DK (held double for a worsted weight), Cascade 220 Superwash, and Knit Picks Swish Worsted are all excellent. These yarns have better stitch definition and softness than big-box options without a significant price jump.

For a splurge-worthy option, consider a 100% merino like Malabrigo Rios, Madelinetosh Tosh Merino, or Lani by The Fibre Company. These yarns are incredibly soft, have beautiful depth of color, and produce a finished fabric that feels luxurious. They are on the pricier side, but for a heirloom-quality gift, they are hard to beat.

How Long Will This Take?

This is one of the most common questions knitters ask before starting a project, and the answer honestly depends on your speed and how often you knit. For an average knitter working on the stated worsted weight version, expect somewhere between 15 and 25 hours of knitting time total. If you knit for an hour each evening, you could finish this blanket in two to three weeks.

The seed stitch rhythm is so automatic once you get going that many knitters find themselves making faster progress than expected. There is something meditative about the knit-purl-knit-purl rhythm that makes it easy to settle in and just keep going.

A Note on Gifting

A handmade baby blanket is one of the most cherished gifts a person can receive. It represents hours of time and care poured into something purely for the comfort of a child not yet born, or newly arrived. When you gift a knitted blanket, consider attaching a small tag with the fiber content and care instructions so the parents know how to wash it. A simple card that says “hand knitted with love, machine wash cold, tumble dry low” goes a long way toward making sure your work survives years of use.

You might also consider gifting the blanket with a small bag of the same yarn, so if the blanket ever wears out in a spot, the parents have something to darn with. This is a thoughtful touch that experienced knitters appreciate even if newer recipients might not fully understand it yet.
