Free Knit Pillow Pattern With Crochet Bobble Border | Pillow Cover Knitting Pattern
There is something deeply satisfying about making your own home décor, and a handmade pillow cover sits at the top of that list. It is one of those projects that feels achievable on a weekend afternoon, yet the finished result looks polished enough to display proudly in any room. Today I am sharing a free knit pillow pattern with a crochet bobble border — a design that combines two crafts in one delightful project and gives your finished pillow cover a texture and personality you simply cannot buy off a shelf.
Whether you are a knitter who has always been curious about crochet, or a crocheter who wants to dip a toe into knitting, this pattern was made for you. The knitted body is clean and classic, and the crocheted bobble border adds that irresistible dimensional detail that makes everyone who walks past your sofa reach out and touch it. Let’s get into everything you need to know to make this pillow cover from start to finish.
Why You Will Love This Knit Pillow Cover Pattern
Before we dive into yarn weights and needle sizes, let me tell you why this particular design stands out from other free pillow patterns you might find.
First, it is genuinely beginner-friendly for the knitted portion. The main body uses a simple stitch pattern — stockinette or a basic textured stitch — that allows a newer knitter to build confidence while still producing something beautiful. The tension does not have to be perfect because the crochet border draws the eye and frames the fabric in a way that is forgiving of slight inconsistencies.
Second, the crochet bobble border is a wonderful introduction to bobble stitches for those who have not tried them. Bobbles are made by working several incomplete double crochet stitches into the same stitch and then completing them together, creating a little popcorn-like bump that pops to the front of your work. Once you make your first one, you will want to put bobble borders on everything.
Third, this project is extremely economical. A standard 18-inch pillow insert requires only about 200 to 250 yards of bulky or super bulky yarn for the knitted body, and a small additional amount for the crochet border. You can use up leftover skeins, combine two complementary colors, or keep everything in a single neutral tone for a more minimalist look.
Finally, the pattern is completely free. No sign-up required, no paywall to navigate. It is here, laid out step by step, so you can cast on today.
Materials You Will Need
Getting your materials sorted before you begin makes the whole process smoother. Here is what you will need to make one 18-inch square pillow cover.
Yarn: Approximately 200 to 250 yards of bulky weight yarn (size 5 or 6) for the knitted body. You will need an additional 50 to 75 yards in either the same color or a contrasting color for the crochet bobble border. I love using a soft merino blend or an acrylic-merino mix for projects like this because the fabric stays smooth and the colors stay vibrant wash after wash.
Knitting Needles: US size 10 (6mm) or US size 10.5 (6.5mm) straight or circular needles. The exact needle size will depend on your gauge and the specific yarn you choose, so always knit a swatch first.
Crochet Hook: US size J/10 (6mm) crochet hook for the bobble border. If your crochet tension tends to be tight, go up to a K/10.5 hook.
Additional Supplies: A blunt tapestry needle for weaving in ends and seaming, scissors, stitch markers, and an 18-inch pillow insert. You will also want a few buttons or a zipper if you prefer a closure over an envelope back — though the envelope back method described here requires no additional hardware and is the easiest option for beginners.
Gauge
Gauge matters more for a pillow cover than people often assume. Because this is not a garment, you have a little more flexibility, but if your gauge is significantly off you may end up with a cover that does not fit your pillow insert properly.
Knitting gauge: 14 stitches and 20 rows = 4 inches in stockinette stitch on US size 10 needles with bulky weight yarn.
If you are getting more stitches per inch, go up a needle size. If you are getting fewer, go down a needle size. Knit a 6-inch swatch, wash and block it, then measure the center 4 inches to get an accurate reading.
Understanding the Stitch Pattern
The main body of this pillow cover uses a seed stitch texture for the front panel. Seed stitch alternates knit and purl stitches across every row, which creates a beautiful, slightly bumpy fabric that has wonderful visual interest without requiring you to follow a complex chart. It also lies flat naturally, which makes it ideal for pillow panels since you do not have to worry about curling edges.
Seed Stitch (worked over an odd number of stitches):
Every row: K1, P1, K1; repeat from to end.
That is all there is to it. Because the stitch count is odd, the pattern self-aligns row after row, and you will never have to think about whether you are on a right-side or wrong-side row.
For the back panels, you can use plain stockinette to save time, since the back of the pillow will not be visible most of the time. Stockinette also creates a slightly tighter, more structured fabric that holds the envelope overlap together neatly.
Pattern Instructions: Knit Pillow Cover Front
Cast on 33 stitches using your US size 10 or 10.5 knitting needles and bulky weight yarn.
Work in seed stitch as follows: K1, P1, K1; repeat from to end of row.
Continue working every row in seed stitch until the piece measures 18 inches from the cast-on edge, ending after completing a full row.
Bind off loosely in pattern, meaning knit the knit stitches and purl the purl stitches as you bind off. A loose bind-off is important here because the crochet border will be worked directly into the edge stitches, and a tight bind-off can pucker the fabric.
Weave in your ends but do not block yet — you will block the entire piece after the crochet border is attached.
Pattern Instructions: Knit Pillow Cover Back Panels
The back of this pillow cover uses an envelope closure, which means you will knit two overlapping rectangles instead of one full square. This is a technique beloved by pillow-makers everywhere because it requires no zipper, no buttons, and no buttonholes, yet keeps your pillow insert securely in place.
Back Panel A (top flap):
Cast on 33 stitches.
Work in stockinette stitch (knit on right side, purl on wrong side) for 11 inches.
Work 4 rows of seed stitch to create a neat finished edge on the overlap.
Bind off in pattern.
Back Panel B (bottom flap):
Cast on 33 stitches.
Work 4 rows of seed stitch to create a neat finished edge on the overlap.
Continue in stockinette stitch for 11 inches.
Bind off loosely.
When both back panels are placed against the front panel, the seed stitch edges will overlap in the center of the back by about 4 inches, creating the envelope opening through which you will insert your pillow form.
Assembling the Pillow Cover Before the Border
Before adding the crochet bobble border, you need to assemble the three knitted pieces into one pillow cover shell. This is done with mattress stitch or whip stitch, depending on your preference.
Lay your front panel right side up on a flat surface. Place Back Panel B at the bottom, aligning raw edges at the bottom and both sides, right side facing down against the front panel. Place Back Panel A at the top, aligning the top and side edges, also right side facing down. The two back panels will overlap in the middle.
Using your tapestry needle and a length of yarn, seam all four sides using mattress stitch or whip stitch. If using mattress stitch, work along the side edge bars for an invisible seam. If using whip stitch, work through both layers along the outermost stitches.
When you finish seaming, turn the cover right side out through the envelope opening and press the seams flat with your hands. You should now have a complete pillow cover that is ready for its crochet border.
The Crochet Bobble Border
This is where the magic happens. The crochet bobble border frames the entire pillow cover and gives it that luxurious, textured edge that makes this project so visually striking. You will work the border directly into the edge stitches of the knitted fabric, picking up through the outermost loops around the perimeter.
If you have never added a crochet border to a knitted piece before, do not be intimidated. The key is to insert your crochet hook through the fabric itself rather than working into a chain, and to space your stitches evenly so the border lies flat without ruffling or pulling.
How to Make a Bobble:
A bobble in this pattern is made by working 5 double crochet stitches into the same stitch, leaving each one incomplete (yarn over, insert hook, yarn over, pull through, yarn over, pull through 2 loops — stop here, leaving 2 loops on the hook), and then pulling through all 6 loops on the hook at once. This creates a compact, round bubble that pops toward the right side of the work.
Bobble Border Pattern:
With the right side of the pillow cover facing you and your crochet hook and bobble border yarn, join yarn with a slip stitch to any corner stitch.
Round 1 (foundation round): Chain 1. Work single crochet evenly around the entire perimeter of the pillow cover, working 3 single crochet into each corner stitch to turn the corners neatly. When you return to the starting corner, slip stitch to the first single crochet to join. Do not turn.
The goal of this foundation round is to create an even base of single crochet stitches into which you will work the bobbles. Take your time spacing stitches evenly — roughly one single crochet per stitch along the knit edges and one single crochet per two rows along the side edges tends to produce a flat border.
Round 2 (bobble round): Chain 2 (this does not count as a stitch). Work 1 bobble into the next stitch, chain 1, skip 1 stitch; repeat from around, working (1 bobble, chain 1, 1 bobble, chain 1) into each corner single crochet. Slip stitch to the top of the first bobble to join.
Round 3 (finishing round): Chain 1. Work 1 single crochet into the top of each bobble and 1 single crochet into each chain-1 space around, with 3 single crochet into each corner. Slip stitch to join. Fasten off and weave in all ends.
The finished border should sit flat against the pillow surface with the bobbles popping forward in a regular, rhythmic pattern. If your border ruffles, you have worked too many stitches and should try again with fewer. If it pulls in and distorts the pillow shape, you need to add more stitches.
Finishing and Blocking
Blocking is the step that transforms a handmade project from “handmade” to “artisan.” Even a simple blocked pillow cover looks finished and professional in a way that an unblocked one does not.
To wet block, submerge the finished pillow cover in cool water and gently press out the air bubbles. Let it soak for 10 to 15 minutes, then remove it and gently press out the water without wringing. Lay it flat on a blocking mat or a clean towel and use rustproof pins to shape it into a perfect square, making sure each side measures 18 inches. Pay special attention to the corners, pinning them into sharp right angles.
Allow the piece to dry completely before removing the pins — this can take anywhere from a few hours to overnight depending on your yarn and the humidity in your environment.
Once dry, insert your 18-inch pillow form through the envelope opening on the back. The pillow form should fit snugly; if you are finding it too loose, your gauge may have been slightly off, but a simple fix is to use a 20-inch pillow insert inside an 18-inch cover for a fuller, more professional look.
Color and Yarn Suggestions
One of the most enjoyable parts of any free knitting pattern is the chance to make it your own through color choices. Here are a few combinations that work beautifully with this particular pillow cover design.
A warm ivory body with a terracotta bobble border creates an earthy, Southwestern-inspired look that suits natural linen sofas and rattan furniture. A deep charcoal body with a creamy white border is timeless and works in almost any living space. For a more playful approach, try a blush pink body with a contrasting dusty sage border — this combination has a soft, botanical quality that looks stunning in bedroom settings.
If you want to keep the whole project in one color, a deep forest green or a rich burgundy in a single yarn throughout gives the pillow a moody, cozy feel. The bobbles still show up beautifully against the seed stitch background even when worked in the same color, because the texture creates its own contrast through shadow and dimension.
For yarn brands, any quality bulky weight yarn will work well. Lion Brand Wool-Ease Thick & Quick is a popular and widely available choice that comes in dozens of colors. Paintbox Simply Chunky is another excellent option with a lovely matte finish. If you want to splurge a little, Malabrigo Chunky in any of their hand-dyed colorways produces an absolutely stunning result.
Troubleshooting Common Issues
Even experienced knitters and crocheters run into small challenges when trying a new pattern. Here are the most common issues with this project and how to solve them.
If your front panel is puckering along the edges after you attach the crochet border, the border tension is too tight. Try going up one hook size and working into every stitch more loosely in the foundation round.
If your bobbles are not popping forward distinctly, make sure you are pulling through all loops firmly at the end of each bobble. A tentative pull leaves the bobble flat. A confident, firm pull draws all the loops together and creates that satisfying round bump.
If your seed stitch panel is curling at the edges before assembly, do not worry — this is normal for stockinette but should not happen with seed stitch. If you see significant curling, double-check that you are truly alternating knit and purl stitches on every row. Seed stitch that is accidentally worked as ribbing (where knit stitches line up above knit stitches) will pull inward significantly. Check your work by looking at the texture — seed stitch should look bumpy and pebbly, while ribbing looks like vertical columns.
Making This Pattern Your Own
This free knit pillow pattern is designed to be a wonderful starting point, but I encourage you to adapt it in whatever direction calls to you. You could work the main body in a cable stitch instead of seed stitch for a more traditional, heritage look. You could use a simple lace pattern for the front panel and pair it with a smooth, neutral bobble border for a delicate, romantic style.
The bobble border itself can be modified by changing the spacing — placing bobbles every stitch instead of every other stitch creates an extremely dense, plush border, while spacing them every third stitch gives a more open, scattered effect.
You can also scale this pattern up or down for different pillow insert sizes. For a 12-inch accent pillow, cast on 22 stitches and work to 12 inches. For a 20-inch pillow, cast on 37 stitches and work to 20 inches. The seed stitch pattern is fully scalable as long as your stitch count remains odd.
A Few Final Thoughts
A handmade pillow cover is one of those gifts that carries genuine warmth with it, whether you are making it for yourself or for someone you love. This free knit pillow pattern with crochet bobble border brings together two crafting traditions in a single approachable project that produces beautiful, tactile results. The seed stitch body knits up quickly and meditatively, and the bobble border gives you just enough of a challenge to keep things interesting from start to finish.
