Hilma — Blanket Free Knitting Pattern

There is something quietly radical about a blanket. It is not a garment that demands to be seen, not an accessory that announces itself when you walk into a room. A blanket simply exists to wrap around you, to soften the edges of a hard day, to be passed from the sofa to the armchair and back again without ceremony. And yet, when you knit one yourself — when every stitch carries the memory of an evening well spent — a blanket becomes something else entirely. It becomes an heirloom in the making.

The Hilma Blanket is named for Hilma af Klint, the Swedish artist who painted bold, geometric, and deeply spiritual work decades before the abstract expressionists claimed that territory as their own. Her canvases were full of symmetry and surprise, of colors that spoke to one another across the composition with an almost conversational warmth. That same spirit lives in this pattern: structured enough to keep your hands purposeful, open enough to let the yarn tell its own story.

This is a free knitting pattern suitable for confident beginners and intermediate knitters alike. The construction is straightforward, the stitch pattern deeply satisfying to work, and the finished object — a generous, draping blanket — is the kind of thing you will reach for every single day.

About the Hilma Blanket

The Hilma Blanket is worked flat, back and forth in rows, from the bottom edge to the top. It uses a combination of simple stitches — knit, purl, and a basic yarn-over eyelet — arranged in a repeating geometric motif that creates a subtle textured grid across the surface. The grid effect gives the blanket visual depth without demanding complex techniques, and the stitch pattern is memorizable within just a few repeats, which means you can knit it while watching a film, listening to a podcast, or sitting in companionable silence with someone you love.

The finished blanket measures approximately 48 inches wide by 60 inches long (122 cm by 152 cm), which makes it a generous throw — large enough to cover a full-sized adult from shoulders to feet when seated, and perfectly proportioned for draping over the end of a bed or folding on the back of an armchair.

The pattern is written for one size. If you want a smaller or larger blanket, simply cast on more or fewer stitches in multiples of 12, plus 3 for the selvedge edges, and adjust your yardage accordingly.

Materials

Yarn: Approximately 1,400–1,600 yards (1,280–1,460 meters) of bulky weight yarn (CYCA #6). The sample shown was knitted in a single-ply wool-blend yarn in a warm oatmeal, but this pattern works beautifully in any fiber. A high-twist plied yarn will show the texture most clearly; a single-ply or loosely spun yarn will give a softer, more impressionistic result. If you want to use a worsted weight yarn instead, simply go up to US size 9 or 10 needles and cast on proportionally more stitches to achieve the same finished dimensions — and plan for a significantly higher yardage, somewhere in the range of 2,800–3,200 yards.

Needles: US size 11 (8 mm) circular needles, 40 inches or longer. Circular needles are recommended even though this blanket is knitted flat, because the length of the cord comfortably holds the full cast-on without straining your wrists or crowding the stitches.

Notions: Tapestry needle for weaving in ends, scissors, stitch markers (optional but helpful for keeping track of pattern repeats), and a ruler or tape measure.

Gauge: 11 stitches and 15 rows = 4 inches (10 cm) in stockinette stitch, blocked. Gauge is not critical for a blanket in the way it is for a garment, but matching gauge closely will ensure your finished blanket is close to the stated measurements and that your yarn estimate is accurate. If your swatch comes out larger (fewer stitches per inch), your blanket will be bigger and you will need more yarn. If it comes out smaller (more stitches per inch), your blanket will be narrower and shorter.

Special Stitches

Hilma Eyelet Panel (worked over a multiple of 12 stitches, plus 3): This is the central stitch pattern of the blanket. It creates a repeating grid of small eyelets separated by columns of reverse stockinette. The eyelets align both horizontally and vertically, giving the fabric its distinctive geometric quality. Each eyelet is formed by a yarn-over paired with a decrease on the same row, so the stitch count remains constant throughout.

Selvedge Edge: The first and last stitch of every row is slipped purlwise with the yarn held to the front. This creates a neat, chained selvedge along both long edges of the blanket, which looks tidy on its own and makes seaming or picking up stitches easier if you ever want to add a border.

Pattern Notes

Before you begin, a few notes that will make the process smoother.

Read through the entire pattern at least once before casting on. The stitch pattern has a 12-row vertical repeat, and the first time through, it helps to understand where each row is heading before your needles arrive there.

If you are new to yarn-overs paired with decreases, practice the motion on a small swatch first. The yarn-over in this pattern always comes before a k2tog on RS rows and before an ssk on alternating RS rows, depending on which half of the repeat you are in. This is what gives the eyelet columns their slight lean and the geometric pattern its sense of movement.

Block your finished blanket. This is not optional advice dressed up as a suggestion — blocking genuinely transforms knitted fabric, opening up the eyelets, evening out the tension, and giving the blanket its full drape and dimension. Wet blocking (soaking the blanket in cool water, gently squeezing out excess moisture, and pinning or laying flat to dry) works beautifully for most natural fibers. For acrylic or acrylic blends, steam blocking or spray blocking will give similar results.

Cast On

Using the long-tail cast-on method (or your preferred stretchy cast-on), cast on 135 stitches.

The long-tail cast-on is recommended because it produces a firm, even edge with a small amount of built-in stretch, which complements the selvedge nicely. If you prefer a cable cast-on, a twisted German cast-on, or any other method you are comfortable with, all will work here. Avoid a backward-loop cast-on for this project — it tends to be too loose and can make the first row of knitting awkward.

The Pattern

Setup Row (WS): Slip 1 purlwise wyf, p to last st, slip 1 purlwise wyf.

This establishes your selvedge stitches and ensures your first RS row begins correctly.

Row 1 (RS): Slip 1 purlwise wyf, k1, k4, yo, k2tog, k6; rep from to last st, slip 1 purlwise wyf. (10 repeats across, plus 3 edge stitches.)

Row 2 (WS): Slip 1 purlwise wyf, p to last st, slip 1 purlwise wyf.

Row 3 (RS): Slip 1 purlwise wyf, k1, k4, yo, k2tog, k6; rep from to last st, slip 1 purlwise wyf.

Row 4 (WS): Slip 1 purlwise wyf, p to last st, slip 1 purlwise wyf.

Row 5 (RS): Slip 1 purlwise wyf, k1, k3, k2tog, yo, k1, yo, ssk, k4; rep from to last st, slip 1 purlwise wyf.

Row 6 (WS): Slip 1 purlwise wyf, p to last st, slip 1 purlwise wyf.

Row 7 (RS): Slip 1 purlwise wyf, k1, k3, k2tog, yo, k1, yo, ssk, k4; rep from to last st, slip 1 purlwise wyf.

Row 8 (WS): Slip 1 purlwise wyf, p to last st, slip 1 purlwise wyf.

Row 9 (RS): Slip 1 purlwise wyf, k1, k10, yo, k2tog; rep from to last st, slip 1 purlwise wyf.

Row 10 (WS): Slip 1 purlwise wyf, p to last st, slip 1 purlwise wyf.

Row 11 (RS): Slip 1 purlwise wyf, k1, k10, yo, k2tog; rep from to last st, slip 1 purlwise wyf.

Row 12 (WS): Slip 1 purlwise wyf, p to last st, slip 1 purlwise wyf.

These 12 rows form one complete repeat of the Hilma stitch pattern.

Working the Blanket

Work the 12-row repeat a total of 22 times (or until the blanket measures approximately 58 inches from the cast-on edge, before the final border). Each 12-row repeat measures roughly 3.2 inches (8 cm) in blocked fabric, so 22 repeats gives you approximately 70 rows of main pattern, landing just under 60 inches with the borders included.

It is a good habit to count your stitches at the end of every RS row, particularly in the first few repeats. Yarn-overs are easy to drop or accidentally add an extra one, and catching the error early saves a great deal of frogging later. A stitch count of 135 at the end of every row means everything is on track.

Borders

The blanket has a simple garter stitch border at the cast-on and bind-off edges, which frames the eyelet pattern cleanly and prevents the edges from curling.

Bottom Border: After your setup row, work 8 rows of garter stitch (knit every row, slipping the first stitch of each row as established) before beginning the 12-row stitch pattern repeat. This means your actual cast-on sequence is: cast on, setup row, 8 rows garter, then begin the main pattern.

If you prefer to work the borders at the beginning and end only (without the setup garter at the bottom), you can begin the main pattern immediately after the setup row — the cast-on edge itself, worked in long-tail, provides a relatively stable and attractive edge on its own.

Top Border: After completing your final 12-row repeat (or when the blanket reaches your desired length), work 8 rows of garter stitch, again slipping the first stitch of each row, before binding off.

Bind Off: Using a stretchy bind-off method — the standard bind-off worked loosely, or the Jeny’s Surprisingly Stretchy Bind-Off if you want extra give — bind off all 135 stitches on a RS row. Cut yarn, leaving a 6-inch tail, and pull the tail through the last stitch to secure.

Finishing

Weave in all ends using a tapestry needle. For a neater result, weave each tail in two directions — first along the fabric in one direction for about an inch, then back the opposite way — to anchor it securely without a knot.

Wet block the finished blanket by soaking it in a basin of cool water for at least 20 minutes, allowing the fiber to fully absorb the water. Do not wring or twist the blanket. Instead, lift it gently from the water, supporting its full weight, and press it against the side of the basin to remove the bulk of the water. Roll it in a dry towel and press firmly, then unroll and lay flat on a blocking mat or on a clean dry surface (a bed covered with towels works perfectly). Pin the corners and edges to your target measurements using blocking pins or T-pins, ease out the eyelets gently with your fingers, and allow to dry completely — usually 24 to 48 hours, depending on your climate and the fiber content of your yarn.

Yarn Substitution Tips

The Hilma Blanket is designed to be adaptable. The eyelet pattern shows best in smooth, plied yarns where stitch definition is high, but there is real beauty in working it in something softer and more rustic — a woolly single-ply that blooms with washing, or a linen-cotton blend that will soften beautifully over time and become more pliable with every use.

If you substitute yarn, the most important thing is to match the weight category. A bulky (CYCA #6) yarn on US 11 needles will give you the drape and density that makes this blanket feel substantial without being heavy. Going too far in either direction — toward a super bulky yarn or toward a worsted — will change the character of the fabric noticeably. That said, knitters have made beautiful things by breaking guidelines, so swatch first and trust your hands.

Natural fibers — wool, alpaca, cotton, linen, and their blends — will all respond well to wet blocking, which is the step that really brings this pattern to life. Synthetic fibers can still be used successfully, especially if you choose a yarn with good stitch definition, but steam block carefully and keep your iron or steamer at a safe distance from the fabric to avoid flattening the texture permanently.

A Few Words on the Process

Knitting a blanket is a commitment. It asks something different of you than a pair of socks or a hat does — not more skill, but more patience, more willingness to settle into the rhythm of a thing that will not be finished quickly. Some knitters find this meditative and sustaining. Others find it frustrating, particularly in the long middle section where the blanket does not seem to be growing at all, no matter how many rows you complete.

If you find yourself in that middle stretch and the motivation begins to dip, a few things help. Measuring your work against the pattern rather than against the finished size keeps you oriented — “I have completed 14 of 22 repeats” feels more achievable than “I am still 26 inches short.” Working with a yarn you genuinely love to touch also matters more on a large project than a small one, because your hands will be in contact with it for dozens of hours. And finally, knitting in good company — physically or virtually — turns the long middle into something to look forward to rather than endure.

The Hilma Blanket, worked at its recommended gauge, takes most knitters somewhere between 35 and 55 hours from cast-on to finished object. That sounds like a lot. But spread across evenings and weekend mornings over a few months, it is simply a season of good knitting — which is its own reward, entirely apart from the blanket at the end of it.

Sharing Your Hilma

If you make a Hilma Blanket, please share it. Tag your project on Instagram or Ravelry so other knitters can find it and be inspired. There is something genuinely wonderful about seeing the same pattern interpreted in different yarns and colorways — the same geometry taking on an entirely different feeling depending on whether it is worked in warm terracotta, cool slate blue, deep forest green, or the natural undyed wool of a particular breed of sheep.

Patterns live longer when knitters make them their own. Hilma af Klint worked in secret for years, painting canvases she believed the world was not ready to understand. She was right that they were extraordinary, and she was also right that they needed time. Your blanket does not need to wait. Cast on, settle in, and let the stitches accumulate. The finished thing will be exactly as significant as you make it — which is to say, very significant indeed.
