Lace Block Blanket: Free Knitting Pattern (Plus a Premium Version Worth Every Penny)
There is something quietly magical about a lace blanket. It catches the light in a way that stockinette never quite manages, throws delicate shadows across a couch or a bed, and somehow manages to look both intricate and effortless at the same time. The Lace Block Blanket is one of those projects that sits in that sweet spot between beginner-friendly and genuinely impressive — a design built from repeating lace blocks that are simple enough to memorize after a row or two, yet complex enough that the finished piece looks like you spent months puzzling over a pattern chart.
Whether you are knitting this as a gift, a decorative throw for your living room, or a cozy layer for a nursery, this pattern delivers. Below you will find the complete free version of the Lace Block Blanket pattern, along with notes on the premium upgrade if you want extra sizing options, step-by-step video guidance, and a printable chart.
Why You Will Love This Pattern
Before we dive into the yarn and the needles, let’s talk about why the Lace Block Blanket has become such a popular project in the knitting community.
First, it is modular in spirit. The design is built around individual lace blocks — usually a 12-stitch or 16-stitch repeat — that stack and tile across the fabric. This means you can knit a small lap blanket, a generous throw, or even a crib blanket just by adjusting how many blocks you cast on and how many rows of blocks you complete. The math is forgiving and the design scales beautifully.
Second, the lace pattern itself is memorizable. Unlike some lace designs that require you to consult a chart on every single row, the Lace Block Blanket uses a short, rhythmic repeat that most knitters have stored in their heads by the end of the first block. That makes it a wonderful travel project or a television knitting companion.
Third, the finished fabric is breathable and lightweight without sacrificing warmth. A lace blanket knitted in a good DK or worsted weight wool has enough air movement to be comfortable in summer but enough fiber content to feel cozy on a cool evening.
And fourth — this is the practical one — the pattern looks far more advanced than it actually is. If you have mastered knitting, purling, yarn overs, and basic decreases like k2tog and ssk, you have every skill you need to complete this blanket.
Materials You Will Need
Yarn: Approximately 800–1,200 yards of DK weight yarn, depending on your finished size. The pattern as written produces a lap blanket measuring roughly 36 by 44 inches. A smooth, plied yarn works best for lace because it shows the stitch definition clearly. Avoid single-ply or very fuzzy yarns on your first attempt, as they make it harder to see where your yarn overs have landed.
Good yarn choices include Cascade 220 Superwash, Paintbox Simply DK, Drops Lima, or any DK yarn that you love the feel of. The blanket works beautifully in a single solid or semisolid color, where the lace pattern can really shine. If you choose a variegated or heavily tonal yarn, the color shifts can compete with the lace texture, so keep that in mind.
Needles: US size 6 (4.0 mm) circular needles, 32 inches or longer. Even though this is a flat project knitted back and forth, the circular needle gives you the length to hold all those stitches comfortably. You can certainly use straight needles if you prefer, but for a blanket of this size most knitters find that a long circular makes the project much more manageable.
Notions: Stitch markers (at least 6–8), a tapestry needle for weaving in ends, and blocking mats with pins or blocking wires. Blocking is not optional for lace — it is the step that opens up the yarn overs, evens out the stitches, and transforms your finished knitting from something that looks a little crumpled into something that looks genuinely spectacular. Please do not skip it.
Gauge: 22 stitches and 28 rows over 4 inches in stockinette after blocking. For lace specifically, gauge is more of a guideline than a strict rule — what matters most is that your fabric has a pleasant drape and that the yarn overs open up nicely when blocked. If your swatch feels stiff, go up a needle size. If it feels too loose and floppy, go down a size.
Abbreviations
Throughout this pattern you will see the following abbreviations.
k — knit
p — purl
yo — yarn over
k2tog — knit two stitches together (a right-leaning decrease)
ssk — slip, slip, knit (a left-leaning decrease)
pm — place marker
sm — slip marker
rep — repeat
RS — right side
WS — wrong side
Pattern Notes
This blanket is worked flat, back and forth in rows. The lace pattern is only worked on right-side rows. Wrong-side rows are purled all the way across, which keeps the pattern easy to follow and gives you a natural rhythm: lace on the right side, rest on the wrong side.
The border is a simple 4-stitch garter edge on each side (knit every stitch on both RS and WS), which keeps the blanket from curling and frames the lace blocks cleanly. You will cast on 4 extra stitches on each side to accommodate this border.
Stitch markers are used to separate the lace blocks from the border stitches. This is strongly recommended, especially while you are learning the repeat.
The Free Lace Block Blanket Pattern
Cast On: Using the long-tail cast on, cast on 164 stitches.
This gives you 4 border stitches on each side and 156 stitches for the lace pattern. The lace repeat is 12 stitches wide, and 156 divided by 12 gives you exactly 13 blocks across.
Setup Row (WS): K4, pm, purl to last 4 stitches, pm, k4.
Garter Border Setup (Rows 1–6): Knit every stitch on every row for 6 rows. This creates a neat garter stitch header at the cast-on edge that mirrors the footer you will work at the bind-off.
The Lace Block Repeat
The lace pattern is worked over a 12-stitch, 12-row block. Each full block repeat creates a small diamond or leaf motif depending on how you read the texture. The 12 rows break into two phases: an opening phase where the yarn overs build the motif and a closing phase where the decreases draw it together.
Row 1 (RS): K4, sm, k1, yo, k4, ssk, k2tog, k4, yo; rep from to marker, sm, k4.
Row 2 and all WS rows: K4, sm, purl to marker, sm, k4.
Row 3 (RS): K4, sm, k1, yo, k1, yo, k3, ssk, k2tog, k3, yo, k1, yo; rep from to last block, ending k1, sm, k4. (Note: adjust as needed so the repeat closes cleanly at the marker. See pattern notes below.)
Row 5 (RS): K4, sm, k2, yo, k1, yo, k2, ssk, k2tog, k2, yo, k1, yo, k1; rep from to marker, sm, k4.
Row 7 (RS): K4, sm, k3, yo, k1, yo, k1, ssk, k2tog, k1, yo, k1, yo, k2; rep from to marker, sm, k4.
Row 9 (RS): K4, sm, k4, yo, k1, yo, ssk, k2tog, yo, k1, yo, k3; rep from to marker, sm, k4.
Row 11 (RS): K4, sm, k2tog, k4, yo, k1, yo, k4, ssk; rep from to marker, sm, k4.
Row 12 (WS): K4, sm, purl to marker, sm, k4.
These 12 rows form one complete lace block repeat. Work them for as many vertical repeats as you like. For the lap blanket size described here, work the 12-row repeat a total of 18 times. This gives you 216 rows of lace pattern, which combined with your garter borders produces a blanket approximately 36–38 inches tall.
Adjusting the Size
To make the blanket wider, add 12 stitches to your cast on for each additional block column you want. So for 14 blocks across rather than 13, cast on 176 stitches (168 lace stitches plus 8 border stitches).
To make the blanket longer, simply work additional repeats of the 12-row lace block. Each full repeat adds approximately 1.5 to 2 inches of length depending on your gauge and yarn weight.
For a baby blanket, cast on 92 stitches (84 lace stitches for 7 blocks, plus 8 border stitches) and work the repeat 10–12 times. This gives you a finished size of approximately 16 by 22 inches — perfectly sized for a stroller or a bassinet.
For a full throw, cast on 212 stitches (204 lace stitches for 17 blocks, plus 8 border stitches) and work the repeat 26–28 times. This gets you close to a 48 by 52 inch throw, which is generous and cozy.
Finishing Rows
Once you have completed your final lace block repeat, work 6 rows of garter stitch (knit every stitch on every row) to mirror the cast-on border. Then bind off loosely in knit on the right side. A stretchy bind-off like the Russian bind-off or a simple yarn-over bind-off will keep the edge from puckering.
Weave in all ends securely. Lace fabric moves and stretches during blocking, and a loosely woven end can work its way out.
How to Block Your Lace Block Blanket
Blocking lace is genuinely one of the most satisfying moments in knitting. You pin out something that looks a little dense and uneven, you wet it or steam it, and a few hours later you come back to find a completely transformed piece of fabric.
For wet blocking, soak your finished blanket in cool or lukewarm water with a small amount of wool wash for 20–30 minutes. Do not agitate it or wring it. Gently squeeze out the water, then roll the blanket in a clean towel to remove excess moisture. Lay it flat on your blocking mats and pin it to your desired dimensions, stretching the lace slightly so the yarn overs open up. Use blocking wires along the edges to get a straight, clean border. Leave it to dry completely — this usually takes 12–24 hours depending on your yarn weight and the humidity in your space.
For steam blocking, lay the blanket flat and hold a steam iron a few inches above the surface. Let the steam penetrate the fiber without pressing the iron directly onto the fabric. Then pin as above and allow to cool and set before unpinning.
Tips for Success
Work a gauge swatch, and block your swatch before measuring it. This is especially important with lace because the wet-finishing process changes the way the fabric behaves.
If you find yourself losing your place in the lace repeat, use a row counter or make a small tally on a sticky note. The 12-row repeat is easy to track once you know what to look for — odd-numbered rows are your lace rows and even-numbered rows are your purl rows.
If a yarn over disappears or you realize two rows back that you missed one, do not panic. Because lace relies on the balance between yarn overs and decreases, a missing yarn over will usually show up as a stitch count that is off at the end of the row. Check your stitch count at the end of every right-side row, at least while you are learning the repeat.
Use a smooth contrast color yarn as a lifeline. Thread a piece of smooth scrap yarn through all the live stitches every 12–20 rows. If you make a mistake you cannot fix, you can rip back to the lifeline without losing all your work.
The Premium Pattern: What You Get With the Paid Version
The free pattern above gives you everything you need to knit a beautiful Lace Block Blanket in the lap blanket size. But if you would like more options, more support, and a more polished knitting experience, the premium version is worth considering.
The paid pattern includes four fully written-out sizes: baby blanket, lap blanket, throw, and large throw. Each size has its own complete stitch count, row count, and yardage estimate so you do not have to do any of the math yourself. It also includes a full stitch chart for the lace repeat, which many visual knitters find much easier to follow than written row instructions.
The premium version also comes with a troubleshooting guide that walks you through the most common lace mistakes — dropped yarn overs, accidental extra decreases, twisted stitches in the border — with photographs showing what each problem looks like and exactly how to fix it. For knitters who are newer to lace, this guide alone is worth the small cost of the pattern.
Additionally, premium purchasers get access to a step-by-step video tutorial covering the cast on, the lace block repeat, the garter borders, and the blocking process. The video runs just under two hours and is designed to be watched alongside the knitting rather than watched all the way through first.
The premium pattern is available on Ravelry and Etsy. It is priced at $6.00 USD, which reflects the time that went into writing, testing, and photographing the pattern across multiple yarn weights and needle sizes with a team of test knitters.
Yarn Substitution Ideas
One of the great pleasures of a modular lace pattern like this one is how differently it can look in different yarns. Here are a few directions worth exploring.
A silk-blend DK like Malabrigo Sock (held doubled) gives the blanket a luminous, slightly drapey quality that is absolutely beautiful as a decorative throw or a wedding gift. The sheen of the silk catches the light in the yarn overs and makes the lace pop in a way that pure wool does not.
A cotton or cotton-blend yarn produces a blanket that is machine washable and ideal for warmer climates or summer use. Cotton has less elasticity than wool, which means your tension will feel a little different, but the finished blocked fabric lies beautifully flat and the stitch definition is excellent.
A chunky yarn held on larger needles — say, a bulky weight on US size 10 needles — gives you a completely different, more textural version of the pattern where the lace blocks read as bold graphic elements rather than delicate texture. This version knits up quickly and makes a fantastic last-minute gift project.
Storing and Caring for Your Finished Blanket
Once your blanket is blocked and dry, store it folded in a breathable cotton bag or wrapped in acid-free tissue paper. Avoid plastic bags, which can trap moisture and encourage mildew in natural fibers.
For washing, hand wash in cool water with a gentle wool wash, or use the delicate cycle on your washing machine if your yarn is labeled superwash. Lay flat to dry every time. Lace fabric should never go in the dryer, as the heat can cause the fiber to felt or shrink and will permanently distort the openwork pattern.
With proper care, a well-knitted lace blanket will last for decades. Many knitters find that lace actually improves with washing over time as the fiber blooms and softens.
A Final Word
The Lace Block Blanket is the kind of project that reminds you why you started knitting in the first place. It is meditative without being monotonous, beautiful without being fussy, and useful without being ordinary. Whether you cast on tonight with a skein of soft merino or save the pattern for a winter holiday project, this blanket will reward every hour you put into it.
Knit slowly. Block generously. And enjoy the process.
