Free Knitting Pattern & Tutorial: Cable Knit Pillow — Knitting House Square
There is something deeply satisfying about a cable knit pillow sitting on a sofa. The texture draws you in, the pattern feels almost architectural, and yet the whole thing is warm and homey in a way that no store-bought cushion ever quite manages. If you have been knitting for a while and want to try something that looks impressively complex but is far more approachable than it appears, a cable knit pillow is one of the best projects you can take on. And if you are newer to knitting and ready to move beyond scarves and dishcloths, this might be exactly the right next step.
This post gives you a complete, free knitting pattern and step-by-step tutorial for a cable knit pillow in a classic square format — what we call the Knitting House Square. It is designed to fit a standard 18-inch pillow insert, though we will talk about how to adjust the sizing to suit whatever you have at home. By the time you finish reading, you will have everything you need: the materials list, the abbreviations, the stitch counts, the cable instructions, and plenty of guidance to help you through the trickier moments.
Let’s get started.
Why Make a Cable Knit Pillow?
Before we dive into the pattern itself, it is worth taking a moment to talk about why cable knitting is such a rewarding skill to develop. Cables look like twisted ropes running vertically through the fabric, and they are created by crossing groups of stitches over one another using a cable needle. The technique sounds complicated, and many knitters put it off for years because of that impression — but once you actually do it, most people are surprised by how intuitive it feels.
A pillow is one of the ideal first cable projects because the piece is flat, worked in sections, and finishes quickly enough that you stay motivated throughout. You are not committing to a full sweater’s worth of cable crossings. You are making something you can complete in a handful of evenings, and when you are done, you have a beautiful, functional object that looks wonderful in any room.
Cable knitting also gives you a foundation that opens the door to more complex projects. After this pillow, you will feel ready to tackle cable sweaters, cable blankets, cabled hats, and all manner of textured accessories. This one pattern is genuinely a gateway.
Materials You Will Need
Gathering your materials before you begin saves a great deal of frustration. Here is what you need for the Knitting House Square cable pillow.
Yarn: Approximately 300 to 350 yards of a bulky weight (weight 5) yarn. A wool or wool-blend yarn is ideal because it has natural elasticity, which makes cable crossings easier and gives the finished fabric a beautiful, structured definition. Acrylic and acrylic-blend yarns also work well and are a good choice if washability matters to you. Avoid anything too slippery (like pure silk or bamboo) for your first cable project, as these yarns can make cables harder to manage.
Needles: US size 10 (6mm) straight or circular needles. Circular needles are fine to use even for flat knitting — simply work back and forth as you would with straight needles.
Cable Needle: A cable needle is a short, usually curved or U-shaped needle used to hold stitches temporarily while you cross a cable. They come in several styles; use whichever feels comfortable in your hands. Many knitters prefer a U-shaped or cranked cable needle because stitches are less likely to slide off.
Notions: A tapestry needle for seaming and weaving in ends, scissors, stitch markers (optional but helpful), and a ruler or tape measure.
Pillow Insert: One 18×18-inch pillow insert. These are widely available at craft stores and online.
Gauge
Gauge matters in this project because you want your finished pillow front and back to actually fit the insert. An ill-fitting cover either stretches the insert awkwardly or bunches up with excess fabric, neither of which looks the way you want.
The gauge for this pattern is approximately 14 stitches and 18 rows over 4 inches in stockinette stitch using bulky weight yarn and US size 10 needles. However, cable patterns pull in fabric horizontally, so your cable panel will be slightly narrower per stitch than a plain stockinette swatch would suggest. This is normal, and the pattern accounts for it.
Before you begin, knit a gauge swatch of at least 20 stitches by 24 rows, block it the way you plan to block your finished pillow, and measure. If your gauge is off, adjust your needle size accordingly: go up a needle size if your swatch is too small (more stitches per inch than called for) or down a needle size if it is too large (fewer stitches per inch).

Understanding the Cable Stitch
Before you follow the row-by-row instructions, it helps to really understand what is happening when you work a cable. The C6F and C6B instructions above are the heart of this pattern, so let’s walk through them in plain language.
When you work a C6F, you are crossing six stitches in a way that makes the left-hand group of three travel over the top of the right-hand group of three, toward the front of your work. This creates a cable that twists to the left. When you work a C6B, you are doing the opposite: the right-hand group of three travels over the back, and the cable twists to the right.
In the Knitting House Square, we use both directions to create a rope cable panel down the center of the pillow and two flanking panels on either side. The combination creates a satisfying symmetry that looks deliberate and polished even though it is built from just two cable moves.
Practice the cable cross on a swatch before starting the full pillow if you have never done it before. Work a small swatch of perhaps 12 stitches and try crossing them on the sixth row. After one or two practice attempts, the motion becomes natural and fast.
The Pattern: Knitting House Square Cable Pillow
This pattern creates two identical pieces — a front and a back — which are then seamed together around a pillow insert. The back is worked in a simple rib or reverse stockinette stitch for a clean, classic look that complements the cabled front without competing with it.
Pillow Front
Cast on 64 stitches.
Row 1 (RS): K2, p2, k2, p2, k6, p2, k6, p2, k6, p2, k6, p2, k2, p2, k2.
Row 2 (WS): P2, k2, p2, k2, p6, k2, p6, k2, p6, k2, p6, k2, p2, k2, p2.
Row 3: K2, p2, k2, p2, C6F, p2, C6B, p2, C6F, p2, C6B, p2, k2, p2, k2.
Row 4: Repeat Row 2.
Row 5: Repeat Row 1.
Row 6: Repeat Row 2.
Repeat Rows 1 through 6 until the piece measures approximately 18 inches from the cast-on edge, ending after a Row 6 (a WS row).
Bind off loosely in pattern.
A note on the stitch count: The 64-stitch cast-on accommodates the four cable panels, the rib columns between them, and the edge stitches that frame the design. If you have adjusted your needle size to match gauge and your swatch is correct, this stitch count will produce a piece close to 18 inches wide. Cable fabric has natural elasticity and will relax slightly when blocked.
A note on counting rows: Because cables are crossed on Row 3 and Row 3 only within each six-row repeat, you will quickly develop a rhythm: knit, purl, cable, purl, knit, purl, cable again. Mark your cable rows on a small notepad or use a row counter app on your phone so you never lose track of where you are in the repeat.
Pillow Back
The back of the Knitting House Square is worked in a 2×2 rib, which gives the back a subtle texture, some stretch, and an attractive finish.
Cast on 64 stitches.
Row 1 (RS): K2, p2; repeat from to end.
Row 2 (WS): K2, p2; repeat from to end.
Repeat these two rows until the back measures 18 inches, same as the front. Bind off loosely in pattern.
Finishing Your Pillow
This is where many knitters rush, and it is worth slowing down here. Good finishing makes the difference between a pillow that looks handmade in the best sense and one that looks, well, unfinished.
Weave in your ends first. Use your tapestry needle to weave in all the yarn tails on both pieces before you seam them together. It is much easier to do this now than after the pieces are joined.
Block both pieces. Wet blocking is particularly effective for wool. Soak the pieces in cool water for about twenty minutes, gently squeeze out the excess water (do not wring), and lay them flat on a blocking mat or clean towel. Use rust-proof pins to shape each piece to roughly 18×18 inches, and allow them to dry completely. Blocking evens out your tension, opens up the cable stitches beautifully, and makes seaming much easier because both pieces will be the same size.
Seam three sides. With your tapestry needle and a length of yarn, use mattress stitch to seam the front and back together along three sides with right sides facing out. Mattress stitch creates an almost invisible join on the right side of the work, which gives the pillow a professional appearance. Work slowly and consistently, picking up one bar between stitches on each piece alternately.
Insert the pillow form and seam the fourth side. Slide your 18-inch pillow insert inside the cover, making sure it fills the corners evenly. Then use mattress stitch to close the fourth side. If you would like the cover to be removable for washing, you can leave the fourth side open and sew on a few snaps, buttons, or a zipper before closing it up.
Troubleshooting Common Cable Problems
Even experienced knitters encounter the occasional hiccup with cables. Here are the most common issues and how to solve them.
Cables look loose or sloppy. This is usually a tension issue. When you knit the stitches immediately after a cable crossing, pull your yarn a little more firmly than usual. The extra tug tightens up the base of the cable and gives it a crisper appearance. Some knitters also find that using a needle one size smaller than called for just for the cable rows helps, though this is more advanced and not necessary here.
Stitches fell off the cable needle. It happens to everyone. If your stitches slide off the cable needle before you have worked them back, try using a cable needle with a pronounced U-curve or a stopper at one end. You can also use a short double-pointed needle as a substitute, which is less likely to let stitches escape.
Lost track of which row you are on. Use a row counter or mark your pattern with a pencil after completing each row. The cable cross happens only once every six rows, so if you count six rows and your cable is getting straighter rather than twisted, you have probably missed a crossing row.
The pillow front is wider or narrower than the back. This can happen if you knit the two pieces at different times (when you are more tired or more relaxed, for instance, your tension may differ slightly) or if you did not block both pieces. Block them both, and if they still do not match, you can ease them together during seaming, which works fine within a small margin.
Variations and Customizations
The Knitting House Square is a lovely pattern on its own, but it is also a great foundation for experimentation once you have worked through it once.
Different cable widths. The C6F and C6B used here cross six stitches at a time. You could use a C4F and C4B (crossing four stitches) for a more delicate, tighter cable, or a C8F and C8B (crossing eight stitches) for a bold, rope-like cable. Just adjust your stitch count accordingly.
Different yarn weights. This pattern works beautifully in a worsted weight yarn as well, though you will need to adjust your needle size and stitch count. Worsted gives you a lighter, more drapey fabric, while super bulky yarn makes for a very chunky, cozy pillow that knits up in almost no time at all.
Color. Cables are traditionally worked in a single, solid or semi-solid color because the texture is the star and variegated yarns can make the cable definition harder to see. That said, a tonal yarn — one that shifts through shades of the same hue — can be absolutely stunning in a cable pattern. Experiment with what you love.
Adding fringe or a contrasting back. A contrasting ribbed back in a complementary color, or a simple fringe along the bottom edge of the pillow, can transform the basic Knitting House Square into something that feels more designed and intentional.
Tips for Knitting Success
A few general tips that apply well beyond this specific pattern.
Always read through the entire pattern before casting on your first stitch. Understanding the overall structure of what you are making helps you anticipate each step rather than being surprised by it. It also helps you catch any confusion about abbreviations or techniques before you are three inches into your work and realize you misunderstood something.
Take breaks when you notice your tension changing. Stress, fatigue, and distraction all affect how tightly you hold your yarn, and tension changes show up clearly in knitted fabric. Put the project down for a bit and come back when you are relaxed.
Never be afraid to rip back. Experienced knitters call this “frogging” (because you rip it, rip it), and it is not a failure — it is just part of the process. A few rows of cable crossing done incorrectly will look obviously wrong in the finished pillow, and it is always better to fix the problem than to push through and live with a mistake you will notice every time you look at the finished object.
A Note on Yarn Quantities
The yardage given in the materials list — 300 to 350 yards — is sufficient for both the front and back of the pillow at the stated gauge. However, yarn quantities in knitting are always estimates, because individual knitters’ tension varies and different yarn brands measure their yardage differently. When in doubt, buy an extra skein. There is rarely a downside to having leftover yarn, and running short in the middle of a project is genuinely frustrating.
How to Care for Your Finished Pillow
Caring for your knitted pillow properly will extend its life significantly. If you used a wool yarn, hand washing in cool water with a gentle wool wash is ideal. Lay it flat to dry rather than putting it in the dryer, which can cause wool to felt and shrink. If you used an acrylic yarn, check the ball band for specific washing instructions — most acrylics are machine washable on a gentle cycle in cool water, which makes them practical for everyday use.
Final Thoughts
The Knitting House Square cable pillow is one of those projects that sits at a perfect intersection of accessible and beautiful. It teaches you one of the most foundational skills in the knitter’s toolbox — cable knitting — while producing something genuinely lovely that you will want to display in your home and that makes a wonderful, heartfelt handmade gift.
Work through it once, and you will likely find yourself planning a second one in a different colorway almost immediately. That is the thing about cable knitting: it is one of those techniques that, once learned, becomes quietly addictive in the best possible way.
