20 Free Knit Blanket Square Patterns – Charity Cozy Fall MAL
There is something deeply satisfying about knitting a square. It is a contained little project — a beginning, a middle, and an end — that you can tuck into your bag and work on anywhere. And when you gather twenty of those squares together into a blanket destined for someone who needs a little warmth, the whole thing transforms into something much bigger than yarn and needles. That is the spirit behind our Charity Cozy Fall Mystery Along (MAL): a season-long celebration of texture, color, and community, all wrapped up in the goal of donating warm handknitted blankets to those in need.
Whether you are a seasoned knitter looking for fresh square patterns or a newer maker eager to build your skills one block at a time, this collection of twenty free knit blanket square patterns has something for everyone. We have gathered everything from simple garter and seed stitch squares for beginners to deeply textured cables and lace panels for those who want a challenge. Each square is designed to finish at approximately eight inches blocked, making them perfectly compatible for joining into a standard charity blanket.
Pull out your autumn yarns — the pumpkin oranges, the forest greens, the warm burgundies, the creamy off-whites — and settle in. The season of cozy knitting is officially here.
What Is a Mystery Along (MAL) and How Does This One Work?
A Mystery Along is exactly what it sounds like: a knit-along in which the full picture is revealed gradually over time, one pattern at a time. In a blanket MAL, each release gives you one new square pattern to complete before the next is revealed. By the end of the event, you have enough squares to assemble a full blanket.
Our Charity Cozy Fall MAL runs across the autumn season. Each week a new free square pattern drops, and knitters from all skill levels are invited to join in. The collective goal is to knit at least one blanket’s worth of squares — twenty total — and donate the finished blanket to a local shelter, hospital, nursing home, or charity of your choice. Many participants knit multiple blankets or contribute extra squares to community blanket drives.
You can use any worsted weight yarn you have on hand, whether that means stash-busting a rainbow of scraps or choosing a cohesive color palette that feels distinctly autumnal. The only real requirement is that your yarn be machine washable so the recipients can care for it easily.
Yarn and Needle Recommendations
For consistency across all twenty squares, we recommend a smooth worsted weight yarn (approximately 200 yards per 100g) and US size 7 or 8 (4.5mm or 5mm) needles. Smooth yarn shows stitch definition beautifully, which is especially helpful in the textured and cable squares later in the collection.
Good yarn choices for a charity blanket include Lion Brand Pound of Love, Paintbox Yarns Simply DK (held double), Paintbox Yarns Simply Worsted, Red Heart Soft, and Cascade 220 Superwash. All of these are machine washable, widely available, and affordable enough that you can knit an entire blanket without breaking the bank.
Each square is worked to an eight-inch gauge blocked. Because gauge can vary dramatically between knitters, do swatch and block your first square before committing to the whole project. Blocking is essential — a wet-blocked knitted square will relax and even out in ways that transform even the simplest pattern.
A Note on Charity Giving
Before we dive into the patterns, a word on where to donate. Finished blankets and squares are welcomed by a wide range of organizations. Project Linus chapters across the United States accept handmade blankets for children in hospitals, shelters, and emergency situations. Warm Up America is a nationwide program that collects seven-by-nine-inch sections (which you can easily adapt these squares into) and sews them into full blankets. Local homeless shelters, domestic violence shelters, hospice programs, and senior care facilities are almost always grateful for warm handmade items, especially heading into fall and winter.
If you are unsure where to give locally, a quick call to your nearest shelter or a search through your local yarn shop’s community board will often turn up a drive that needs your squares desperately.
Now — on to the patterns.
The 20 Free Knit Blanket Square Patterns
1. Classic Garter Stitch Square
The simplest possible starting point, and the one every beginner should begin with. Cast on 40 stitches and knit every row until your square measures eight inches. Bind off. Done. Garter stitch is forgiving, lies completely flat without curling, and produces a satisfying ridged texture that holds its shape beautifully. It is also an excellent base for practicing your tension. Use a bright, cheerful autumn color here — burnt orange or golden yellow makes a wonderful first square.
2. Seed Stitch Square
Seed stitch alternates knit and purl stitches across the row and shifts them on each subsequent row, so a knit stitch sits above a purl and vice versa. The result is a bumpy, pebbly texture that is firm, dense, and wonderfully cozy. Cast on an even number of stitches and work every row as k1, p1 to the end, always starting with the stitch that is opposite to what you see below your needle. Seed stitch is a great second project after garter because it introduces the purl stitch in a low-stakes format.
3. Moss Stitch Square
Often confused with seed stitch, moss stitch is worked slightly differently: you work k1, p1 across for two rows before shifting. This creates a subtly elongated texture with a horizontal emphasis. It has a beautiful tweedy appearance in heathered yarns and is particularly flattering in earthy fall tones like olive green or warm brown.
4. Basketweave Square
The basketweave is one of those magical patterns that looks far more complicated than it is. You alternate small blocks of stockinette with small blocks of reverse stockinette — typically five stitches wide and five rows tall — to create a woven, three-dimensional grid. It is a genuinely meditative pattern once you get the rhythm, and it showcases autumn colors with real elegance. This is a great first step into working from a grid-based stitch pattern.
5. Ribbed Square
A simple two-by-two rib — k2, p2 across every row — produces a deeply textured, stretchy square with a lot of visual movement. Because ribbing wants to pull inward, you will want to cast on slightly more stitches than your other squares and allow it to relax fully during blocking. Ribbed squares add a lovely textural contrast when placed next to flatter neighbors in the finished blanket.
6. Diamond Stitch Square
The diamond stitch uses a combination of knit and purl stitches arranged in a simple eight-row repeat to create an all-over diamond pattern. It looks intricate but is entirely achievable from a written pattern or a simple chart. The peaks and valleys of the diamond pattern catch the light beautifully and add enormous visual interest to the finished blanket.
7. Chevron Square
A classic chevron stripe uses strategic yarn overs and decreases to create a zigzag wave pattern. When worked in a single color, the effect is subtle and textural. When worked in two or more colors, it becomes a bold, graphic statement. For the fall MAL, try pairing a deep plum with a warm cream for a truly seasonal feel. Chevron squares are satisfying to knit because the rhythm of the increases and decreases becomes intuitive quickly.
8. Simple Cable Square
No blanket square collection is complete without at least one cable, and this simple four-stitch twist is the perfect place to start if cables are new to you. You will need a cable needle or a spare dpn. The pattern places a central cable panel flanked by reverse stockinette on either side, creating a raised rope effect that feels almost sculptural. Once you have worked your first cable crossing, you will wonder why you ever found it intimidating.
9. Honeycomb Cable Square
The honeycomb cable is an all-over cable pattern made up of interlocking four-stitch cables that cross in alternating directions, creating a dense, hexagonal texture that genuinely resembles honeycomb. It is one of the most beautiful stitch patterns in all of knitting, and it makes an absolutely stunning blanket square. This one will take longer than the simpler squares, so save it for a weekend knit or a movie marathon.
10. Linen Stitch Square
The linen stitch is worked by alternating slipped stitches with yarn held in front against worked stitches, creating a woven, fabric-like texture that is firm and dense. It knits up slowly because you are working every other stitch per row, but the result is a square that feels almost like woven cloth. In a rust or terracotta yarn, linen stitch squares look like little tiles from an autumn market.
11. Eyelet Lace Square
For a lighter, airier option in the collection, the eyelet lace square introduces a simple row of yarn overs and k2tog decreases worked in a grid to create a field of small eyelets. The pattern is easy to memorize and produces a delicate, lacey texture without requiring any real lace knitting experience. It is a lovely contrast to the dense cable and textured squares elsewhere in the blanket.
12. Leaf Motif Square
A single stylized leaf knitted in relief against a reverse stockinette background is the centerpiece of this square. The leaf is built from a central stitch that is increased outward and then decreased back to a single stitch, all in stockinette, so it stands forward against the purl background. It is a wonderful introduction to working a small pictorial motif and feels absolutely perfect for a fall blanket.
13. Flying Geese Square
Inspired by the classic quilting block of the same name, the flying geese knit square uses a series of yarn overs and decreases to create a column of triangular shapes pointing upward, like a flock of geese heading south for the winter. It is one of the most seasonally appropriate squares in the collection and photographs beautifully.
14. Broken Rib Square
The broken rib pattern works columns of knit and purl stitches but interrupts them on alternate rows to create a subtle, almost woven texture that falls somewhere between full ribbing and seed stitch. It is smooth enough to feel modern and graphic but textured enough to add warmth. This square is a great workhorse pattern — versatile, easy to memorize, and endlessly appealing.
15. Star Stitch Square
The star stitch is a cluster stitch that creates tiny raised stars across the fabric. It requires working into the same group of stitches multiple times and passing them off together, which sounds fiddly but quickly becomes second nature. The resulting fabric is thick, dimensional, and deeply cozy — exactly what you want in a charity blanket destined to warm someone through a hard winter.
16. Bobble Square
A field of small bobbles scattered across a stockinette background is playful, tactile, and surprisingly quick to knit once you get the hang of making a bobble (working multiple times into the same stitch, then passing the extra stitches over). This square adds a lot of personality to the finished blanket and is especially charming in a bright, happy color. Children receiving charity blankets tend to love the bumpy texture.
17. Herringbone Square
The herringbone stitch is worked by knitting through the back loop of two stitches at once and slipping the first stitch off, creating a woven diagonal fabric. It is a little unusual in its technique and takes a few rows to get comfortable, but the result — a dense, diagonal tweed-like texture — is absolutely worth the learning curve. It is one of the most distinctive and grown-up looking patterns in the collection.
18. Mitered Square
A mitered square is knitted on the diagonal, beginning with a large number of stitches at the corner and decreasing toward the center on every other row. The result is a square with a beautiful diagonal ridge running from corner to corner. Mitered squares are endlessly satisfying to knit because you can watch them grow toward completion, and they look spectacular in variegated or self-striping yarns.
19. Entrelac-Inspired Square
Entrelac is a technique that creates a woven, basket-like pattern of interlocked rectangles or squares worked at right angles to each other. A simplified entrelac-inspired square uses short rows to create the visual effect of entrelac without the complexity of full pickup-and-knit entrelac construction. It is a fantastic introduction to short row knitting and produces a square that looks breathtakingly complex.
20. Autumn Harvest Sampler Square
The final square of the collection brings together elements from several earlier patterns — a simple cable running up one side, a few eyelets, a column of moss stitch — into a small sampler that celebrates everything you have learned over the course of the MAL. It is a freeform, slightly personal square, and no two will look exactly alike. Think of it as a signature on your finished blanket.
Assembling Your Blanket
Once all twenty squares are knitted and blocked, it is time to join them. The most common arrangement is a four-by-five grid, which produces a blanket approximately 32 by 40 inches when each square finishes at eight inches — a good size for a child’s lap blanket or a small charity throw.
There are several methods for joining squares. Whipstitch seaming worked on the wrong side is the fastest and least visible. Mattress stitch creates an invisible seam on the right side and works beautifully with smooth yarns. The three-needle bind-off joins two live edges simultaneously and creates a ridge on either the right or wrong side depending on how you orient your work. For a decorative touch, a crochet slip stitch join worked on the right side creates a visible ridge that can itself become a design element.
Once your squares are joined, consider adding a simple edging — a few rows of garter stitch or a single crochet border — to neaten the perimeter and give the blanket a polished, finished look.
Tips for a Successful MAL
The best advice for any long-term project like this is to keep your squares together and organized as you go. A project bag dedicated entirely to your MAL squares keeps things tidy and makes assembly much easier. Take a few minutes to block each square as you finish it rather than leaving them all to the end — it is a much less daunting task that way and allows you to check your sizing consistently.
If you are knitting with scraps and multiple colors, lay your finished squares out on a flat surface periodically and audition different arrangements before you commit to seaming. Color placement makes an enormous difference to the overall appearance of the finished blanket.
Connect with other MAL participants on social media using the hashtag #CharityCosyFallMAL. Seeing what other knitters are making is one of the great joys of any knit-along, and the community that forms around charity knitting projects is invariably warm, encouraging, and generous.
Final Thoughts
Knitting a blanket square is a small act. Twenty of them, joined together and given to someone who needs them, is something much more significant. The Charity Cozy Fall MAL is built on the belief that our crafting can be a vehicle for care — that the hours we spend in the gentle rhythm of knit and purl can translate directly into warmth for someone who is cold, comfort for someone who is ill, and beauty for someone who needs reminding that strangers can be kind.
Work through these twenty free knit blanket square patterns at whatever pace suits your life and your schedule. Come back to them when you need a mindful half-hour, or settle in for a long autumn evening and knock out two or three in a row with a cup of tea at your elbow. By the time the last leaves fall, you will have something beautiful, useful, and genuinely good to show for your season.
Happy knitting — and thank you for being part of this.
