How to Crochet the Moss Stitch Diamond Pillow
If you’ve been looking for a crochet pillow project that looks impressive but doesn’t require years of experience to pull off, the Moss Stitch Diamond Pillow might be exactly what you need. This project combines one of the most satisfying and versatile crochet stitches with a bold geometric design, resulting in a pillow that looks custom-made and designer-worthy. Whether you’re decorating your living room, making a thoughtful handmade gift, or just looking for a weekend project that will keep your hands busy, this pillow checks every box.
In this guide, you’ll learn everything from the supplies you need to the finishing touches that make your pillow look polished and professional. Even if you’ve never tried the moss stitch before, don’t worry — it’s one of those stitches that clicks almost immediately and becomes deeply rhythmic and satisfying once you get going.
What Is the Moss Stitch?
Before diving into the pattern, it helps to understand what makes the moss stitch so special. The moss stitch — sometimes called the granite stitch, linen stitch, or woven stitch — is a simple two-row repeating pattern that creates a dense, textured fabric. It alternates chain spaces and single crochets in a way that produces a beautiful woven-looking texture that holds its shape extremely well.
Because the resulting fabric is firm and sturdy, it’s ideal for home décor items like pillows, bags, and baskets. The stitches lock together tightly, so your pillow won’t stretch out of shape or lose its structure over time. And visually, the texture adds incredible depth to any colorwork or geometric design you layer on top.
The diamond pattern in this pillow is worked using two colors, with the moss stitch texture running throughout both. The contrast between the two colors is what makes the diamond shape pop, and because you’re changing colors at the end of rows, there’s no complicated colorwork mid-row to manage.
Skill Level and Time Commitment
This project is best suited for crocheters who are comfortable with the basics — chain stitches, single crochets, and yarn changes — but it is absolutely approachable for ambitious beginners. If you’ve completed at least one or two small projects and feel confident working in rows, you’re ready for this pillow.
As for time, expect to spend somewhere between eight and fourteen hours on this project depending on your pace. It’s a wonderful project to spread across a few evenings or a relaxed weekend. The repetitive nature of the moss stitch makes it easy to pick up and put down, so it’s also a great project to take along on trips or work on while watching television.
Materials You’ll Need
Getting your supplies together before you start will make the whole process smoother. Here’s what you’ll need to crochet the Moss Stitch Diamond Pillow.
Yarn: Choose a medium weight yarn, also labeled as worsted weight or size 4. You’ll need two contrasting colors — one for the background and one for the diamond. Approximately 200 yards of your main color (MC) and 150 yards of your contrasting color (CC) should be enough for a standard 18-inch pillow. Cotton yarn works beautifully for home décor because it’s durable, washable, and holds its shape well, but an acrylic blend works just as well and gives you more color options.
Hook: A size 5.0 mm (H/8) crochet hook is a good starting point for worsted weight yarn, but always check your gauge. If your stitches are coming out too loose, go down a hook size. If they’re too tight, go up.
Pillow Insert: An 18×18 inch pillow insert is the most common size for throw pillows and the size this pattern is designed around. Look for a polyester fiberfill insert, which gives a plump, professional look and holds up well over time.
Other Supplies: You’ll also need a yarn needle for weaving in ends, scissors, and stitch markers to help keep track of your rows and pattern repeats. A ruler or measuring tape will help you check your gauge and dimensions as you go.
Gauge and Sizing
Gauge matters more than some crocheters realize, especially for a project like this where you want the finished piece to fit a specific pillow insert. With a 5.0 mm hook and worsted weight yarn, you should aim for approximately 14 stitches and 16 rows per 4 inches in the moss stitch pattern.
To check your gauge, crochet a small swatch of at least 15 stitches and 20 rows, then measure a 4-inch square in the center. Adjust your hook size as needed until your gauge matches. This small investment of time upfront will save you from finishing a pillow that turns out too large or too small for your insert.
For an 18-inch square pillow, you’ll be working with a foundation chain of approximately 63 stitches (which accounts for the moss stitch pattern requirements) and crocheting until your piece measures about 18 inches in height. You’ll crochet two identical panels — one for the front and one for the back — and seam them together around the pillow insert.
Understanding the Moss Stitch Pattern
Let’s walk through the moss stitch before you apply it to the full diamond design. Once you understand the basic pattern, the diamond colorwork will make much more sense.
Foundation Chain: Chain an odd number of stitches. For practice, chain 21.
Row 1: Single crochet in the second chain from the hook. Chain 1, skip one stitch, single crochet in the next stitch. Repeat the “chain 1, skip 1, single crochet” sequence across the row until you reach the end. Turn.
Row 2: Chain 1, single crochet in the first chain-1 space of the previous row. Chain 1, single crochet in the next chain-1 space. Continue across in this manner, working each single crochet into the chain-1 spaces of the previous row. Turn.
Repeat Row 2 continuously. That’s it — that’s the moss stitch. The magic is in the way each row nestles into the gaps left by the previous row, creating that interlocked, woven look.
After a few rows, you’ll notice the fabric has a beautiful diagonal texture. This is completely normal and part of what makes the stitch so visually interesting. Don’t try to correct it — it’s a feature, not a flaw.
The Diamond Color Chart
The diamond design in this pillow is worked over a field of 63 stitches and 72 rows (for the front panel). The diamond shape is centered on the panel and created by switching between your main color and contrasting color according to a simple chart.
Rather than a complex intarsia technique, this pattern uses horizontal color changes, switching from MC to CC at the end of certain rows. The diamond emerges because specific rows use both colors in alternating sections, which you’ll manage by working with both yarn balls at once during those rows and carrying the unused color loosely up the side.
Here’s a simplified breakdown of how the diamond rows work. The full pattern follows this shape logic:
The first several rows at the bottom of the panel are worked entirely in your main color. As you approach the center of the panel, you’ll begin introducing the contrasting color in increasing widths — first just a few stitches in the center, then more stitches per row, until the contrasting color takes up the widest part of the diamond. Then the contrasting color section decreases symmetrically until the diamond closes at the top, and you finish the remaining rows in the main color.
A good rule of thumb for a centered diamond on a 63-stitch panel: start the contrasting color section at the center stitch of row 20, expanding by two stitches on each side per row for approximately 16 rows until the diamond reaches its widest point, then decreasing by two stitches per row for 16 rows until the diamond closes at row 52. The remaining rows above and below are worked entirely in the main color.
If you prefer to work from a visual chart, graph paper works perfectly. Map out your 63 stitches across and 72 rows up, shade in the diamond shape in the center, and follow the shading row by row as you crochet. Many crocheters find this visual reference indispensable for keeping track of where they are in the design.
Step-by-Step Instructions
Now let’s put everything together and walk through the complete pillow, start to finish.
Step 1 — Make Your Foundation Chain
Using your main color and a 5.0 mm hook, chain 64. This gives you 63 working stitches once you account for the turning chain.
Step 2 — Begin the Moss Stitch
Work Row 1 of the moss stitch as described above, then continue in the moss stitch pattern for 19 rows in your main color. At the end of each row, turn your work and chain 1 before beginning the next row.
Step 3 — Introduce the Contrasting Color
At the end of row 19, before turning, join your contrasting color yarn and leave the main color hanging on the side. Beginning at row 20, work the center stitch in your contrasting color (just one stitch at this stage), and use your main color for the stitches on either side.
To do this without tangling your yarn, keep your CC yarn ball on one side of your work and your MC on the other. When you reach the point in a row where you need to switch colors, simply drop the current color and pick up the next one, carrying the unused yarn loosely across the wrong side of the work.
Step 4 — Expand the Diamond
For each subsequent row, add one stitch on each side of the contrasting color section. So row 21 uses CC for 3 center stitches, row 22 for 5 center stitches, and so on. Continue expanding until the CC section spans the widest point of your diamond.
Step 5 — Close the Diamond
Once you’ve reached the widest point, begin subtracting one stitch from each side of the CC section per row. Mirror the expansion perfectly so your diamond is symmetrical.
Step 6 — Finish in Main Color
Once the diamond has closed, cut your contrasting color yarn and weave in the end. Continue working the remaining rows in main color only until your panel measures 18 inches from the foundation chain.
Step 7 — Crochet the Back Panel
Work a second panel in the same dimensions, but this time work entirely in your main color. This gives the pillow a clean, solid back that lets the diamond front shine. Alternatively, you can make the back panel with a simple single crochet or half double crochet stitch rather than the moss stitch, which saves a little time and yarn.
Assembling the Pillow
Now for the satisfying part — putting it all together.
Weave in all remaining ends on both panels. Block your panels lightly if needed by dampening them and laying flat to dry. This is especially helpful if you used cotton yarn, which can sometimes be a bit stiff and benefits from a gentle block to even out the stitches.
Hold your two panels together with the wrong sides facing each other. Using your main color and a yarn needle or crochet hook, seam three sides of the pillow together. A whip stitch works perfectly here, as does a single crochet seam worked through both panels simultaneously (which creates a nice decorative ridge along the edge).
Once three sides are seamed, insert your pillow form. Fluff it gently to push the filling into all corners, then seam the final side closed.
Tips for a Beautiful Finished Pillow
A few small details make a big difference in how your finished pillow looks and lasts.
When changing colors mid-row, always pull the new color through the last two loops of the final single crochet in the old color. This ensures clean, crisp color changes with no muddiness at the transition points.
Weave in your ends thoroughly — at least four to five inches in different directions through the fabric — so they won’t come loose with use and washing. The tight structure of the moss stitch makes this easier than it sounds because the stitches hold the yarn ends securely.
If you notice your color-change yarn is creating loose loops or puckers on the wrong side of your work, try tensioning the carried yarn more firmly as you work. A little practice and you’ll find the right tension naturally.
For the crispest diamond edges, use a yarn with good stitch definition. Smooth, tightly spun cottons and wool blends tend to show colorwork more clearly than fuzzy or loosely spun yarns.
Caring for Your Moss Stitch Diamond Pillow
Once your pillow is finished, you’ll want to keep it looking great. If you used cotton yarn, your pillow cover can typically be machine washed on a gentle cycle in cold water and laid flat to dry. If you used acrylic, most acrylic blends are fully machine washable and even dryer-safe on low heat — always check your yarn label to be sure.
Remove the pillow insert before washing the cover, or use an insert in a removable cover so your whole pillow is easy to clean.
Why This Pattern Is Worth Your Time
The Moss Stitch Diamond Pillow is one of those projects that teaches you a lot while still being genuinely enjoyable throughout. You’ll deepen your understanding of the moss stitch, get comfortable with simple colorwork and color changes, and end up with a finished object that looks far more complicated than the process actually was. It’s the kind of project people ask about when they see it on your couch, and the kind you’ll feel proud to say you made yourself.
Whether you’re a crocheter who loves having a tangible goal to work toward or someone looking to learn a new stitch in a practical context, this pillow delivers on every front. Try it in muted neutrals for a minimalist aesthetic, bold contrast colors for something dramatic, or even multiple shades for a gradient effect that takes the design in a whole new direction. The moss stitch and the diamond template are infinitely adaptable, and once you’ve made one, you’ll likely find yourself planning the next color combination before you’ve even finished seaming the first.
Happy crocheting — and enjoy the pillow!
