Granny Square Pillow – FREE Crochet Pattern
If you’ve been crocheting for any length of time, you already know that granny squares hold a special place in the heart of this craft. They are the first motif many of us ever learned, the project that turned a confusing tangle of yarn into something recognizable and satisfying. But granny squares aren’t just for blankets anymore. One of the most rewarding ways to use them is to build them into a cozy, colorful pillow that adds personality to any sofa, chair, or bed. Today I’m sharing a complete, free crochet pattern for a granny square pillow that is suitable for beginners and endlessly customizable for seasoned crocheters.
Whether you’re working through your yarn stash, making a handmade gift, or simply looking for a weekend project that feels both nostalgic and fresh, this pillow pattern has you covered.
Why Granny Square Pillows Are Worth Making
Before we dive into the pattern itself, let’s talk about why this project deserves a spot on your crochet to-do list.
First, granny squares are portable and fast. Each square takes very little time to complete, which means you can work on them in small bursts — during a lunch break, while waiting at an appointment, or during the commercials of your favorite show. Because the work is broken into small, manageable units, this project never feels overwhelming.
Second, granny squares are a perfect stash buster. You don’t need to buy new yarn for this project if you don’t want to. Almost any worsted weight yarn you have on hand will work beautifully. Mixing colors from different skeins is actually part of the charm. Traditional granny squares have always celebrated the use of leftover yarn, and that heritage makes this pattern wallet-friendly as well as creative.
Third, a pillow is a finished object that you’ll actually use. It lives in your home, gets touched and leaned against, and makes people ask where you bought it. When you say you made it yourself, the reaction never gets old.
Materials You Will Need
To make one granny square pillow measuring approximately 16 inches by 16 inches, you will need the following:
Yarn: Worsted weight yarn (Category 4) in your chosen colors. For a classic look, choose three or four contrasting colors. You’ll need roughly 200 yards of your main color and about 100 yards each of your accent colors. Acrylic yarn is durable and easy to wash, making it a practical choice for a pillow. Cotton or cotton-blend yarns also work well and give the finished piece a slightly structured feel.
Hook: A size 5.0mm (US H/8) crochet hook is standard for worsted weight yarn, but always crochet a gauge swatch and adjust your hook size up or down as needed.
Pillow insert: One 16-inch by 16-inch pillow form. These are widely available at craft stores and online. You can also refill an old pillow if you have one in the right size.
Yarn needle: For weaving in ends and seaming the squares together.
Scissors: A small, sharp pair works best.
Stitch markers (optional): Helpful for keeping your place, especially if you’re new to working in rounds.
Gauge
One complete granny square worked in the pattern below should measure approximately 8 inches by 8 inches after a light blocking. Since you will need four squares total to cover both sides of a 16-inch pillow insert, gauge matters. If your square is coming out smaller, try a larger hook. If it’s coming out larger, try a smaller hook.

Understanding the Classic Granny Square Structure
A traditional granny square is built from the center out in rounds. Each round adds a layer to the square, and the corners are formed by working cluster stitches separated by chain spaces. The beauty of this construction is that it is endlessly expandable — you can keep adding rounds to make the square as large as you want, or stop at any size that suits your project.
For this pillow, each square will be worked to seven rounds. If you want a different final size, you can add or remove rounds accordingly and adjust the number of squares you make.
The Granny Square Pattern
Make four squares total: two for the front panel and two for the back panel. You can work all four in the same color arrangement, alternate the colorways, or go completely scrappy with a different palette for every single round.
Setting up: Begin with a magic ring, or chain 4 and join with a slip stitch to form a ring. The magic ring gives a neater center but either method works.
Round 1 (Color A): Chain 3 (counts as first double crochet throughout). Work 2 double crochets into the ring. Chain 2. Work 3 double crochets into the ring, chain 2. Repeat the section between asterisks two more times. Join with a slip stitch to the top of the beginning chain 3. You now have four groups of 3 double crochets separated by four corner chain-2 spaces. Fasten off Color A.
Round 2 (Color B): Join Color B with a slip stitch into any corner chain-2 space. Chain 3, work 2 double crochets in the same corner space, chain 2, work 3 double crochets in the same corner space. This creates your first corner cluster. Chain 1, then work a corner in the next chain-2 space by working 3 double crochets, chain 2, 3 double crochets. Repeat from asterisk two more times. Chain 1, join with a slip stitch to the top of the beginning chain 3. Fasten off Color B.
Round 3 (Color C): Join Color C in any corner chain-2 space. Chain 3, 2 double crochets in same space, chain 2, 3 double crochets in same space (corner made). Chain 1, work 3 double crochets in the chain-1 side space, chain 1, then work a corner in the next chain-2 corner space. Repeat from asterisk around. Join and fasten off.
Round 4 (Color A): Join Color A in any corner space. Work the same structure as before, adding one additional 3-double-crochet cluster separated by chain-1 spaces along each side as you go. Each side will now have two groups of side clusters between the corners. Join and fasten off.
Round 5 (Color B): Continue in the same manner, adding another cluster to each side. Each side now has three groups of side clusters. Join and fasten off.
Round 6 (Color C): Repeat the expansion. Each side now has four groups of side clusters. Join and fasten off.
Round 7 (Color A — the border round): Join Color A in any corner space. Instead of working the clusters-with-chain-1 pattern, work a solid border by doing: corner cluster in each corner space, and single crochets across each side, working 1 single crochet into each stitch and each chain-1 space along the way. Work 3 single crochets into each corner chain-2 space to keep the corners flat. Join and fasten off.
This border round adds structure and makes it much easier to seam the squares together cleanly.
Assembling the Pillow
Once you have all four squares complete, weave in all your ends carefully. This step is worth doing thoroughly because ends that aren’t well-secured can work their way out over time with use.
Blocking: Lightly dampen each square and pin it to a flat surface in a square shape. Allow it to dry completely. Blocking evens out the stitches, straightens the edges, and makes seaming significantly easier. Even if you’re using acrylic yarn and are doing “wet blocking” rather than steam blocking, a quick soak and a gentle reshape makes a noticeable difference.
Seaming the front panel: Take two of your four squares and hold them with right sides facing each other. Using your yarn needle and a length of yarn in your main color, join them along one edge using a whip stitch or a mattress stitch. A whip stitch is faster; a mattress stitch creates a nearly invisible seam. Either works well. After joining the first two, you have a rectangle. These two squares together form the front panel of your pillow.
Seaming the back panel: Join the remaining two squares the same way to create the back panel.
Assembling front and back: Place the front panel and the back panel with wrong sides facing each other (so that right sides face outward). Using your yarn needle and main color yarn, join three sides with your chosen stitch, working through both layers simultaneously. Before you close the fourth side, insert your 16-inch pillow form. Then seam the final side closed.
Some crocheters prefer to add buttons or a zipper closure on the back panel to make the cover removable for washing. If that appeals to you, work the back seam only halfway on the fourth side, sew on a few buttons, and create corresponding button loops with chains on the opposite edge.
Color Inspiration and Variations
Part of the joy of granny square projects is the near-infinite possibility when it comes to color. Here are a few approaches to spark your creativity.
Traditional rainbow: Work each round in a different color cycling through red, orange, yellow, green, blue, and violet, with a neutral like cream or white as the final border. This is the look most people associate with vintage granny squares, and it never goes out of style.
Modern neutral: Use three shades of the same neutral family — ivory, warm beige, and a deep taupe — for a sophisticated, contemporary look that fits into minimalist or Scandinavian-inspired home decor.
Bold two-color contrast: Choose one very dark color and one very bright color, alternating rounds. Black and mustard, navy and coral, or forest green and cream all create striking graphic results.
Ombre or gradient: Work the four squares using yarns from the same color family but in different values, so the squares themselves shift from light to dark. Arrange the squares so the gradient reads across the whole pillow face.
Scrappy: Pull out every bit of leftover yarn in your stash and just go. No planning, no matching — each round in whatever yarn is next in the pile. This approach often produces the most joyful and unique results.
Tips for a Polished Finished Pillow
A few details separate a pillow that looks homemade in the best possible way from one that looks unfinished.
Consistent tension is the most important factor. Try to keep your yarn tension even throughout, especially when switching colors. If you tend to crochet tightly when you start a new color, take a breath and consciously loosen up for the first few stitches.
Matching your seam color to the dominant color of your squares helps the joins disappear. If you’re working with a very scrappy pillow, use a neutral gray or beige for the seaming.
Don’t rush the weaving-in of ends. Thread each tail onto your yarn needle and run it through the backs of stitches in at least two directions, making a small bend in the yarn path so it can’t pull straight out. Clip the end close to the work after securing.
If you want extra durability — particularly if the pillow will get heavy use or if you’re gifting it to someone with kids or pets — consider whip-stitching around the entire outer seam of the assembled pillow a second time for reinforcement.
Sizing Up or Down
This pattern is written for a 16-inch pillow, but granny squares are infinitely scalable.
For an 18-inch pillow, add one more round to each square and use a slightly larger pillow insert. For a lumbar pillow shape, make two squares and join them side by side to create a panel, then make a matching back and assemble as described. For a 12-inch pillow, work smaller squares — stop at five rounds instead of seven — and check your gauge again.
You could also make a single large granny square for the front panel and a solid flat panel for the back, which reduces the seaming work and gives a clean contrast between the textured front and the smooth back.
Caring for Your Finished Pillow
How you care for the pillow depends on the fiber content of your yarn. Acrylic yarn is machine washable and dryer safe on low heat, making it very practical for a pillow that will live in a frequently-used space. Wool or wool blends should be hand washed in cool water and laid flat to dry to avoid felting and shrinkage. Cotton is also typically machine washable but may wrinkle more in the dryer, so a low heat setting or air drying is better.
Check the label on your yarn for specific care instructions and store that information somewhere you can find it — your future self will thank you when the pillow needs its first wash six months from now.
Make It a Set
Once you’ve completed one granny square pillow, you’ll find yourself wanting to make another. The squares work up quickly once you have the muscle memory for the construction, and having a matching set of two or three pillows on a sofa creates a coordinated, intentional look that feels more like interior design than simple craft.
You can also expand the concept into a granny square cushion cover for a dining chair or bench, a floor pouf with extra stuffing, or even a travel pillow. The basic construction is the same wherever you take it.
Final Thoughts
There’s something genuinely satisfying about making a granny square pillow. It combines the meditative pleasure of working in rounds with the practical reward of an object you’ll use every single day. It’s a project that welcomes every skill level, works with almost any yarn, and produces a result that looks far more complex than it actually is.
I hope this free pattern gives you everything you need to cast on — or chain up — your own version. If you make one, I’d love to see it. Share your photos in the comments or tag me on social media. And if you have friends who are just learning to crochet, this is one of those patterns worth passing along. A granny square pillow is a wonderful first finished object, and the skills it teaches carry forward into almost every other crochet project you’ll ever make.
Happy crocheting!
