How To Make A Chunky Knit Pillow: A Complete Step-by-Step Guide
There is something undeniably cozy about a chunky knit pillow. The thick, rope-like texture, the satisfying weight, the way it instantly makes a sofa or bed look like something out of a design magazine — it is one of those home décor pieces that looks expensive but can be made at home for a fraction of the cost. Whether you are a seasoned knitter or someone who has never picked up a pair of needles, making a chunky knit pillow is one of the most accessible and rewarding DIY projects you can take on.
This guide will walk you through everything you need to know, from choosing the right yarn and tools to casting on, knitting the panels, and assembling the final pillow. By the end, you will have a beautiful, handmade piece that adds warmth and texture to any room in your home.
Why Chunky Knit Pillows Are Worth Making at Home
Before we get into the how-to, it is worth understanding why so many people are turning to handmade chunky knit pillows. Store-bought versions can run anywhere from $40 to over $150 depending on the size and brand. When you make your own, you control the size, the color, the texture, and the quality of the materials — all while spending significantly less.
Beyond the cost savings, there is a creative satisfaction in making something with your hands. Chunky knit pillows are particularly well suited to beginners because the oversized stitches are easy to see and work with, mistakes are simple to spot and fix, and the project moves quickly compared to fine-gauge knitting. A standard throw pillow can be completed in a single afternoon or spread across a relaxing weekend.
They also make thoughtful, personalized gifts. A handmade chunky knit pillow in someone’s favorite color or the exact dimensions to fit a specific spot on their couch is the kind of gift that stands out.
What You Will Need
Getting the right materials before you start will make the entire process smoother and more enjoyable. Here is a full list of what you will need for a standard 18×18 inch chunky knit pillow.
Yarn: You will need bulky or super bulky yarn, typically labeled as weight 5, 6, or 7 on the yarn weight scale. Merino wool roving yarn is a popular choice because it is incredibly soft and gives that classic chunky, cloud-like look. You can also use arm knitting yarn, which is thicker and spun specifically for large-scale projects. For an 18×18 pillow, plan on approximately 200 to 250 yards of super bulky yarn, though this can vary depending on your stitch tension. Popular colors include cream, ivory, oatmeal, gray, and dusty sage, but honestly any color you love will work beautifully.
Knitting Needles: For a chunky knit pillow, you will want large circular or straight needles in US size 17 (12mm), US size 19 (15mm), or even US size 35 (19mm) depending on your yarn weight. Circular needles are often more comfortable for handling the bulk of the yarn and the growing weight of the fabric. If you prefer straight needles, make sure they are long enough to accommodate all your stitches — at least 14 inches.
Pillow Insert: An 18×18 or 20×20 inch pillow insert works well for a standard throw pillow. Going up one size in the insert (using a 20×20 insert for an 18×18 knitted cover) gives the finished pillow a fuller, more plump appearance. Down or down-alternative inserts give the softest result, but polyester fiberfill inserts are more affordable and still look great.
Tapestry Needle: You will need a large-eye tapestry or yarn needle to seam the panels together and to weave in your ends.
Scissors: A sharp pair of scissors for cutting yarn.
Optional — Zipper or Buttons: If you want to be able to remove the knitted cover for washing, you can add a zipper or a row of buttons along the back seam. This is entirely optional but practical if the pillow will see heavy use.
Understanding the Basic Stitch
The most common stitch used for chunky knit pillows is the stockinette stitch, which creates that classic V-shaped pattern you see in most knit fabrics. It involves alternating rows of knit and purl stitches. Many chunky knit pillow patterns use all knit stitches (called garter stitch), which creates horizontal ridges and lies flatter without curling at the edges — making it ideal for beginners.
If you have never knitted before, here is a quick breakdown of the two foundational stitches you will use.
The knit stitch is worked by inserting the needle tip into the front of the stitch on your left needle from left to right, wrapping the working yarn counterclockwise around the right needle, pulling the wrapped yarn through the stitch, and sliding the old stitch off the left needle. Repeat this across the row.
The purl stitch is essentially the knit stitch in reverse. Insert the right needle tip into the front of the stitch from right to left, wrap the working yarn counterclockwise, pull it through, and slide the stitch off. For a beginner making their first chunky pillow, sticking to all knit stitches (garter stitch) for every row is the simplest approach and produces a beautiful, textured result.
Step-by-Step Instructions
Step 1: Cast On Your Stitches
For an 18×18 inch pillow front worked in super bulky yarn on US size 19 needles, you will typically cast on between 12 and 16 stitches. The exact number depends on your gauge — how many stitches per inch your yarn and needle combination produces. To find your gauge, knit a small swatch of about 10 stitches for 4 to 5 inches, then measure how many stitches fit within one inch. If you get approximately 1 stitch per inch, cast on 18 stitches for an 18-inch width. Most super bulky yarns on large needles fall somewhere between 1 and 1.5 stitches per inch.
To cast on, make a slip knot and place it on your needle. This counts as your first stitch. Use the long-tail cast-on method or the knitted cast-on method to add the remaining stitches. The long-tail cast-on creates a neat, sturdy edge that is perfect for a pillow. Hold the needle in your right hand, the tail of the yarn over your left thumb, and the working yarn over your left index finger. Dip the needle down through the loop on your thumb, pick up the yarn from your index finger, pull it through, and slide the thumb loop off. Repeat until you have the desired number of stitches.
Step 2: Knit the Front Panel
With your stitches cast on, begin knitting every row in garter stitch (knit all stitches on every row). Work until your piece measures 18 inches in length, or whatever size matches the width of your pillow insert. Because chunky yarn knits up quickly, you may reach 18 inches in as few as 20 to 25 rows depending on your yarn and needle size.
As you work, keep your tension consistent. With chunky yarn, it is easy to knit loosely on some rows and tightly on others, which can make your fabric uneven. Try to pull the working yarn with the same amount of snugness each time you form a stitch. Practicing on your gauge swatch before starting the main piece is a great way to settle into a consistent rhythm.
Step 3: Bind Off and Set Aside
When your front panel reaches the right length, it is time to bind off. Knit the first two stitches normally, then use the left needle tip to lift the first stitch over the second stitch and off the right needle — this is one bound-off stitch. Knit one more stitch, then lift the second over the third. Continue in this way across the row until only one stitch remains. Cut the yarn leaving an 8-inch tail, and pull the tail through the last stitch to secure it. Weave in the tail with your tapestry needle and set the front panel aside.
Step 4: Knit the Back Panel
Repeat steps 1 through 3 to create an identical back panel. Some knitters prefer to make the back panel in a simpler stitch or even use a complementary fabric like fleece or linen for the back of the pillow, which saves yarn and time. This is a perfectly valid approach and gives the pillow a clean, fabric back that makes inserting and removing the pillow form much easier.
If you choose a fabric back, cut your fabric to the same dimensions as your knitted front panel plus a half-inch seam allowance on all sides. A polar fleece back in a matching or complementary color works especially well because the edges do not fray, eliminating the need to hem.
Step 5: Block Your Panels (Optional but Recommended)
Blocking is the process of wetting or steaming your knitted fabric to help it relax, even out, and settle into its final dimensions. It is not strictly required for a chunky knit pillow, but it can make seaming much easier and gives the finished piece a more polished look.
To wet block, soak the knitted panels in cool water for about 20 minutes. Gently squeeze out the excess water — do not wring — then lay the panels flat on a clean towel. Roll the towel up with the knitting inside and press firmly to absorb more moisture. Unroll, then pin the panels to their final dimensions on a foam blocking mat or a spare towel on the floor. Let them dry completely before seaming, which may take 24 to 48 hours.
Step 6: Seam the Panels Together
Lay your front and back panels together with the wrong sides facing each other (the bumpy, less tidy side of your fabric facing inward). Thread your tapestry needle with a length of matching yarn approximately three times the perimeter of your pillow.
Use mattress stitch to seam three sides of the pillow together. To work mattress stitch on garter fabric, pick up the horizontal bar between two rows on one panel, then pick up the corresponding bar on the opposite panel. Pull gently to draw the two edges together. This stitch creates an almost invisible seam that lies flat and does not add bulk.
Seam the bottom edge, then up one side, then across the top. Leave the fourth side open for inserting the pillow form.
Step 7: Insert the Pillow Form and Close the Seam
Slide your pillow insert inside the cover. Adjust it so it fills the corners evenly and the cover is smooth and taut. Once the insert is positioned, continue seaming the final open edge closed using the same mattress stitch. Secure your yarn with a few small knots on the inside, weave in the end, and trim any excess.
If you added a zipper or button closure, attach it now along the open edge before closing the seam permanently.
Tips for Getting the Best Result
Getting your gauge right is the single most impactful thing you can do to ensure your pillow turns out the size you intended. Even a small difference in tension compounds over many stitches and rows, so always knit a swatch and measure it before starting.
Choose a yarn that will hold up over time. Superwash merino, wool-acrylic blends, and chunky cotton all wear well and can be gently washed. Pure roving wool is beautiful but can felt (irreversibly mat together) if it gets wet and agitated, so keep that in mind if the pillow will live in a high-use space.
Do not skip weaving in your ends properly. A tapestry needle woven through several stitches in different directions is far more secure than a simple knot, especially with a pillow that gets squeezed and fluffed regularly.
If your finished pillow looks a little thin or flat, the fix is simple: go up one size on your pillow insert. The extra filling stretches the knit fabric slightly and makes everything look fuller and more luxurious.
Creative Variations to Try
Once you have made your first chunky knit pillow, the variations are nearly endless. You can experiment with cable stitches, which involve crossing groups of stitches over each other to create rope-like twists running vertically through the fabric. Cables look incredibly impressive but are more straightforward than they appear, and chunky yarn makes the process easy to follow.
Color blocking is another beautiful option — knitting sections of the pillow in different colors to create bold horizontal or vertical stripes. You can also try a seed stitch pattern, which alternates knit and purl stitches within the same row to create a bumpy, highly textured surface that looks quite different from garter or stockinette.
For an extra luxurious pillow, consider using two strands of bulky yarn held together as one. This doubles the thickness of your fabric and creates a wonderfully dense, weighty pillow that feels incredibly substantial.
Caring for Your Chunky Knit Pillow
Most chunky knit pillows can be spot-cleaned by dabbing gently with a damp cloth and mild soap. If the entire cover needs washing, check the care label on your yarn. Wool yarns typically need to be hand-washed in cool water and laid flat to dry, while acrylic and cotton yarns are often machine washable on a gentle cycle in a mesh laundry bag.
Avoid hanging your knitted pillow cover to dry, as the weight of the wet fabric will stretch it out of shape. Always dry flat.
Store any extra yarn from your project in a cool, dry place away from direct sunlight, which can fade colors over time.
Final Thoughts
Making a chunky knit pillow is one of those projects that delivers enormous satisfaction relative to the time and skill it requires. The materials are affordable, the technique is beginner-friendly, and the result is something genuinely beautiful that you can be proud of. Whether you are making it for your own living room, gifting it to someone special, or just looking for a creative way to spend a Sunday afternoon, this project checks every box.
Start with a simple garter stitch pillow in a neutral tone to get comfortable with the process, then build toward more complex textures and color combinations as your confidence grows. Before long, you will have an entire collection of handmade pillows — and a very well-decorated home.
