Materials you’ll need
Yarn
– Type: Worsted-weight yarn works beautifully for this project. You can also use DK-weight if you prefer a lighter cover, but you’ll need to adjust your needle size and gauge accordingly.
– Yardage: Plan for two identical squares, approximately 300–350 yards per square when knitted in garter stitch on size US 8 needles. For colorwork or stripes, add extra yardage as needed. If you’re using a single color throughout, you’ll likely need around 600–700 yards total. If you want to switch colors halfway through or create a stripe pattern, keep an extra skein within reach.
– Color: Pick a color that matches your decor or go for a soft neutral as a versatile base. You can also create a two-tone square by using contrasting colors for a simple stripe effect.
Needles
– Size: US size 8 (5.0 mm) are a great starting point for a sturdy, plush fabric in worsted weight. If your gauge differs, you may choose US 7 (4.5 mm) or US 9 (5.5 mm) and adjust the number of stitches.
– Type: Straight needles work fine since you’ll knit flat back-and-forth to make a square. Circular needles are optional if you prefer the flexibility, but not required.
Notions
– Tapestry needle for weaving in ends.
– Stitch markers (optional; helpful if you plan any edging or color changes).
– Scissors.
– A pillow form insert (optional but recommended for a crisp finish). For a 16×16 inch cover, a 16×16 inch pillow form works well. If you’re not using a form, you can add extra seam allowance or work with a fabric pillow insert.
Gauge and sizing notes
– The pattern described here yields a roughly 16×16 inch square. The final size will depend on your gauge (stitches per inch and rows per inch). To ensure a snug fit, knit a quick swatch in garter stitch: cast on 20 stitches and knit every row for 20–25 rows to measure width and height. If your fabric is looser or tighter than the target, adjust your cast-on stitches and the number of rows accordingly.
– If your gauge is looser, you may end up with a larger square; if tighter, a smaller one. The key is consistency across both squares. Try to match the stitch count on both fronts.
Pattern overview
– We’ll knit two identical garter-stitch squares, each roughly 16×16 inches.
– Then we’ll sew the two squares together to form a pillow cover with an opening for inserting a pillow form.
– Finishing touches include weaving in ends, adding a neat seam, and optional decorative edging or stripes.

Cast on
– Cast on 60 stitches (you can adjust to suit your gauge, but 60 is a suitable starting point for a square around 16 inches wide in garter stitch with worsted weight on a typical gauge).
Work garter stitch
– Row 1 (RS): Knit all stitches.
– Row 2 (WS): Knit all stitches.
– Repeat Rows 1 and 2 for 60 rows, or until your piece measures about 16 inches from cast-on edge to the top edge (up to you to verify with a ruler or measuring tape).
Finish one square
– Bind off loosely all stitches.
– Weave in ends on the wrong side. Block lightly if desired to settle the fabric, but avoid stretching.
Repeat for the second square
– Cast on 60 stitches and repeat the exact same steps to create an identical second square.
Important note on size
– If you find your squares are a little larger or smaller than 16 inches, don’t worry. The pillow insert can be sized accordingly, or you can adjust with a slightly smaller or larger pillow form. The pattern is flexible; aim for two squares that are the same size so they align evenly when sewn together.
Assembling the pillow cover
Layout
– Place the two squares with the right sides facing each other (the “right side” is the public, textured side of garter stitch; the wrong side is the inside).
Seaming
– We’ll seam three sides first, leaving one edge open for inserting the pillow form. A simple, invisible method is the mattress stitch. If you’re not comfortable with mattress stitch, you can seam with a backstitch or a simple whip stitch.
Step-by-step seaming
– Align the edges carefully; make sure the corners match.
– Beginning at one corner, place the needle into the first stitch of the front square and the corresponding stitch of the back square, pulling the thread snug but not tight. Use a running, ladder-like motion along the edge to create an even seam.
– Repeat along the two side edges and the bottom edge, ensuring your seam is neat and consistent.
– Leave the top edge open for now to insert the pillow form, or plan to leave the opening at the bottom edge depending on your preference.
Inserting the pillow form
– Turn the cover right-side out through the open edge. If you left the top edge open, carefully slide the pillow form into the cover.
– Adjust the corners so they align cleanly and the fabric sits flat.
Closing the opening
– Once the pillow form is inside, close the opening with a neat, concealed stitch. A simple ladder stitch or whip stitch works well and helps hide the seam. If you prefer, you can whip-stitch the opening along the edge inside, or you can tuck the edge in and sew it down with a few slips of invisible stitches for a cleaner look.
Optional finishing touches
– Decorative edge: If you’d like a little extra polish, add a decorative edge along the top or bottom edge. You can pick up a round of stitches around the perimeter and knit a thin, garter-stitch border in a contrasting color, or you can crochet a simple i-cord edge to give a neat frame. For best results, work a few rows of garter stitch in the contrast color and bind off loosely to maintain the pocket’s shape.
– Stripes or color blocks: If you prefer stripes, switch colors after a certain number of rows (for example, after every 20 rows) and continue knitting in garter stitch. Since garter stitch has two identical sides, stripes will be even and bold without curling. If you’re comfortable with simple colorwork, a two-color stripe pattern can yield a modern look without complicated techniques.
– Button-back or envelope-style opening: If you’d rather a top closing with buttons or an envelope-style back, you can knit the back square slightly larger and trim it to fit, or add a simple button and loop closure along the top edge when you assemble. This is completely optional but can make remove-and-wash easier.
Care and maintenance
Because this pillow is hand-knit in worsted-weight yarn, it’s a good idea to treat it with care to extend its life.
– Most worsted-weight yarns in acrylic or nylon blends are machine washable on a gentle cycle and can be tumble-dried on low heat, though air-drying is best to maintain the shape.
– If you use natural fibers like wool, consider hand washing in cold water with a mild detergent. Lay flat to dry to prevent stretching.
– Avoid excessive direct sunlight for long periods to prevent color fading.
How to customize and adapt
This pattern is intentionally simple, making it easy to adapt to your space and skill level. Here are some ideas:
– Color blocking: Knit the front square in one color, the back in another, or add a narrow stripe of a third color around the edge for a graphic look.
– Mixed textures: Instead of pure garter stitch, try seed stitch or ribbing (for example, knit 1, purl 1 across and then purl 1, knit 1 on the next row for a 1×1 rib). Note that changing stitch patterns will affect the size of the square, so knit a swatch first.
– Larger or smaller cover: If you want a larger pillow, increase the cast-on stitches proportionally and knit until your square is, for example, 18×18 inches. For a smaller pillow, reduce the cast-on stitches and adjust the number of rows so the square remains square.
– Themed or seasonal pillows: Swap yarn colors to reflect seasons or holidays. Consider pastel colors for spring, earthy tones for fall, or bold primaries for a modern look.

Common questions about this pillow pattern
– Will garter stitch make the pillow square curl? No. Garter stitch lies flat on both sides and forms a sturdy square. It’s ideal for a pillow cover that stays square and doesn’t curl at the edges.
– Can I use a different weight yarn? Yes. If you choose a lighter weight yarn (like DK), you’ll need to adjust needle size and the number of stitches to maintain a similar final size. It’s a good idea to knit a small gauge swatch and measure before committing to full squares.
– How do I decide the final pillow size? The finished square size will depend on yarn weight, needle size, and your knitting tension. A quick gauge swatch will help you determine how many stitches and rows you need to reach a desired dimension. Then cast on accordingly and knit until you achieve the target size.
– What if I don’t have a pillow form? You can use a fabric pillow insert or stuff with fiberfill for a patchwork look. If using fiberfill, consider knitting a slightly larger square to accommodate the filling and a more forgiving seam.
Tips for success and common pitfalls
– Tension matters: Aim for even tension throughout the rows to avoid ripples or bulges. If your stitches look loose, switch to a slightly smaller needle or adjust your cast-on count.
– Match your two squares exactly: It’s worth taking a few minutes to compare the two squares before seaming to ensure they match in width and height. If one is slightly larger, you can trim edges carefully or slightly rip back and reknit a few rows to match.
– Weaving in ends: Plan to weave in ends on both squares as you go to avoid a mess at the end. The garter stitch lies flat, so the ends won’t poke out much if you weave them in properly.
– Blocking is optional but helpful: A light block after knitting can help the squares lie flat and align perfectly for seaming. Do a gentle steam block or a light wet block, being careful not to stretch the fabric beyond its natural size.
Alternative finishing ideas
– Enveloping back for easy removal: Knit a back piece that is the same size as the front, then seam all around three sides to create an envelope-style opening at the top. This makes removing the pillow form quicker for washing.
– Hidden zipper: For a more polished look and easy washing, you can install a small hidden zipper along one edge. This requires a corresponding zipper insertion pattern, but it yields a professional finish.
A note on eco-friendly and budget-friendly choices
Choosing yarn you already have is a fantastic way to keep costs down while reducing waste. If you’re buying new, consider skeins labeled with recycled content or opt for locally produced yarns. Garment-grade yarns and natural fibers can be a joy to work with, but ensure they’re durable enough for regular use in a living space.
Wrapping up
A hand-knit cozy square pillow is a warm, practical project that can elevate a couch or bed with minimal effort. The garter-stitch pattern is forgiving, beginner-friendly, and yields a satisfyingly plush texture that both looks and feels luxurious. With two matching squares, careful seaming, and a well-chosen pillow insert, you’ll have a beautiful, handmade pillow cover ready to cozy up any room.
If you’re new to knitting or want more ideas, try varying the color palette or the stitch texture on your next pillow cover. You can even create a set: a pair of pillow covers in complementary colors, or a trio of pillows that mix textures (garter, seed, and rib) for a layered, tactile look. The best part of a hand-knit pillow is its personal touch—each seam and stitch is a little bit of your time and care that makes your space feel uniquely yours.
