Free Pattern Friday: Chunky Seed Stitch Knit Rug Pattern
There is something deeply satisfying about making something for your home with your own two hands. When that something also happens to be warm underfoot, beautiful to look at, and built to last, you have a project worth talking about. Today’s Free Pattern Friday is exactly that kind of project: a chunky seed stitch knit rug that you can whip up in a weekend and enjoy for years to come.
Whether you are a seasoned knitter looking for a quick and rewarding home décor project, or a confident beginner ready to try something a little more substantial than a dishcloth, this pattern is for you. Grab your biggest needles, pull out that bulky yarn, and let’s make something gorgeous for your floor.
Why a Knit Rug?
Before we dive into the pattern itself, let’s talk about why a hand-knit rug deserves a spot on your project list. Store-bought rugs are fine, of course. But there is something a hand-knit rug does that no mass-produced floor covering can: it tells a story. Every stitch was placed by your hands. The color is exactly what you chose. The size fits the awkward little landing at the top of your stairs, or the narrow strip beside your bed, or that bare patch in front of the kitchen sink.
Hand-knit rugs are also remarkably durable when made with the right materials. Chunky cotton, jute-blend yarn, or upcycled fabric strips hold up beautifully to foot traffic. They are easy to wash, easy to repair if something goes wrong, and they only get better-looking with a little wear.
The seed stitch, which we are using for this pattern, is a particularly great choice for a rug. It creates a dense, bumpy, highly textured fabric that lies flat without curling at the edges — a common frustration with knit projects. The alternating knit and purl stitches lock the fabric in place and give you that satisfying, almost woven look that makes people stop and ask, “Did you make that?”
Yes. Yes, you did.
About the Seed Stitch
If you have never worked seed stitch before, do not be intimidated. It is one of the most beginner-friendly stitch patterns in knitting, requiring nothing more than a knowledge of the knit stitch and the purl stitch alternated in a specific way.
Here is the basic concept: in seed stitch, you knit the stitches that appear to be purls, and you purl the stitches that appear to be knits. This is the exact opposite of ribbing, which knits the knits and purls the purls. The result is a checkerboard-like texture where no two adjacent stitches look the same. It is visually interesting without being complicated, and it grows quickly on large needles.
For a rug, this texture is pure gold. It provides gentle grip (helpful on hard floors when used with a rug pad), it adds visual warmth to a room, and it hides minor inconsistencies in your tension better than a smooth stockinette fabric would. Even if your knitting is not perfectly even — and most of ours is not — a seed stitch rug looks intentionally rustic and beautifully handmade.
Materials You Will Need
This pattern is written for a finished rug measuring approximately 20 inches by 30 inches, which is a great size for a bath mat, a bedside rug, or a small entryway piece. You can easily adjust the size by casting on more or fewer stitches and working more or fewer rows — more on that in the sizing notes below.
Yarn: Approximately 200–250 yards of super bulky weight yarn (weight 6) in the color of your choice. For a rug that will hold up to real foot traffic, look for 100% cotton, a cotton-blend, or a specially made rug yarn. Some knitters also love using a T-shirt yarn or fabric yarn for this project, which gives the finished rug a lovely, slightly soft underfoot feeling.
Needles: US size 13 (9mm) straight or circular needles. Circular needles can be easier to manage with a heavy, wide project, even if you are knitting flat, because they allow the weight of the work to rest in your lap rather than on the needle tips.
Notions: Scissors, a tapestry needle for weaving in ends, and a rug pad for underneath the finished rug (especially important on hardwood or tile floors).
Gauge: Approximately 8 stitches and 12 rows = 4 inches in seed stitch on US 13 needles. Because this is a rug, gauge is not critical — a slightly larger or smaller rug is perfectly fine — but do swatch if you want to hit a specific size.
A Note on Yarn Choices
The yarn you choose for a rug matters more than it does for, say, a hat or a cowl. Softness is lovely but durability is the priority here. A yarn that pills or breaks down quickly is going to leave you with a sad-looking rug after just a few months of use.
Here are some yarn types that work beautifully for this pattern:
100% Cotton Yarn: This is a perennial favorite for knit rugs. Cotton is washable, durable, and gets softer with every wash. It does not stretch out of shape the way wool can, which means your rug will hold its dimensions beautifully over time. Look for a tightly twisted cotton in a super bulky weight.
Jute or Jute-Blend Yarn: If you love the look of natural fibers and want a slightly more rustic, earthy feel, jute is a wonderful option. It is stiff to knit with but creates an incredibly sturdy fabric. It works best in low-traffic areas or as a decorative accent rug.
T-Shirt Yarn (Zpagetti or Similar): Made from recycled jersey fabric strips, T-shirt yarn is chunky, squishy, and available in the most incredible range of colors and prints. It is a sustainable choice and knits up beautifully on large needles. The finished fabric has a pleasant, slightly padded feel underfoot.
Acrylic or Acrylic-Blend: While not ideal for high-traffic rugs, a chunky acrylic works fine for decorative rugs in low-traffic areas. It is widely available, affordable, and easy to care for. Just know that it may pill more quickly than cotton.
The Pattern
Abbreviations
k — knit
p — purl
CO — cast on
BO — bind off
st(s) — stitch(es)
rep — repeat
RS — right side
WS — wrong side
Instructions
Cast On: Using your long-tail cast on (or any cast on you prefer), CO 40 stitches.
Row 1 (RS): K1, p1; rep from to end of row.
Row 2 (WS): K1, p1; rep from to end of row.
That’s it. That is the entire stitch pattern. Repeat rows 1 and 2 until your work measures approximately 30 inches from the cast-on edge, or until you reach your desired length. Bind off loosely in pattern (knitting the knit stitches and purling the purl stitches as you bind off) to keep the edge elastic and even.
Weave in your ends securely using a tapestry needle. Because this is a rug and will experience some pulling and movement, it is worth weaving each end in two directions — forward and then back — to make sure nothing works loose over time.
That is your finished rug.
Block lightly if needed by dampening the fabric and patting it into shape on a flat surface. Allow to dry completely before placing on the floor.
Sizing Notes and Adjustments
One of the best things about this pattern is how easy it is to customize. The seed stitch works over any number of stitches — even or odd — as long as you remember the rule: always knit the purls and purl the knits. Here are some guidelines for making your rug bigger or smaller.
Small Bath Mat or Bedside Rug (approximately 18″ x 24″): Cast on 36 stitches and work until the piece measures 24 inches.
Standard Bath Mat (approximately 20″ x 30″): Cast on 40 stitches and work until the piece measures 30 inches. This is the size written in the pattern above.
Larger Entryway Rug (approximately 24″ x 36″): Cast on 48 stitches and work until the piece measures 36 inches.
Runner (approximately 18″ x 48″): Cast on 36 stitches and work until the piece measures 48 inches.
For any size, if you want to be precise about your stitch count, do a quick gauge swatch first. Knit a small square, measure it, and use that measurement to calculate how many stitches you need to cast on for your desired width. For most people working with super bulky yarn on US 13 needles, you will get approximately 2 stitches per inch — so a 20-inch wide rug needs roughly 40 stitches.
Color Options and Variations
This pattern is stunning in a single solid color — there is something very clean and architectural about a monochromatic chunky rug. But it is also a fantastic canvas for a little creativity.
Stripes: Change colors every 10 or 20 rows for a bold stripe pattern. Simply drop one color and pick up the next, leaving a 6-inch tail to weave in. Wide stripes in two or three colors look particularly striking.
Gradient or Ombre: If you can find a self-striping bulky yarn, or if you want to manually transition between several shades of the same color (say, cream to oatmeal to warm brown), the seed stitch texture makes the gradient look incredibly rich and organic.
Neutral Naturals: Creamy white, warm oatmeal, soft gray, and natural linen tones all look stunning in seed stitch. If you are going for a Scandinavian or minimalist home aesthetic, a neutral chunky rug is the perfect finishing touch.
Bold Brights: On the other end of the spectrum, a rug knit in mustard yellow, terracotta, forest green, or deep navy makes an incredible statement piece. In a room with neutral walls and furniture, a colorful hand-knit rug becomes the focal point of the whole space.
Tips for Success
A few notes that will make the process smoother and the finished rug even better.
Use a rug pad. Regardless of what type of floor you are placing your rug on, a non-slip rug pad underneath it is a must. It prevents sliding (which is a safety issue), reduces wear on the rug’s underside, and keeps it looking great longer.
Cast on loosely. A tight cast-on edge on a rug looks awkward and can cause the rug to pucker. Use the long-tail cast on with a slightly relaxed tension, or go up one needle size just for the cast-on row.
Bind off loosely, too. Same logic applies. Binding off in pattern — knitting the knits and purling the purls as you bind off — helps, as does consciously keeping your tension relaxed during the bind-off row.
Weave in ends very securely. This cannot be overstated. Rugs get walked on, dragged, folded, washed. Ends that are just barely woven in will work their way out. Take an extra minute to weave in each end thoroughly.
Wash before use. Give your new rug a gentle machine wash (or hand wash) and lay it flat to dry before putting it on the floor. This sets the stitches, removes any stiffness from the yarn, and gives you a chance to block it into shape.
Caring for Your Knit Rug
With proper care, a well-made knit rug can last for many years. Here are some simple guidelines.
Wash your rug on a gentle cycle in cold water, or hand wash it in the sink with a mild detergent. Avoid hot water, which can cause some yarns to shrink or felt. Do not put a knit rug in the dryer — the heat and tumbling can distort the shape and damage the fibers. Lay it flat on a clean surface or hang it over a drying rack, patting it into shape while it is still damp.
For day-to-day maintenance, a quick shake outside removes dust and debris. A light vacuuming on a low setting (without a beater bar) keeps the surface looking fresh. If something spills, blot it immediately with a clean cloth and cold water — rubbing will only work the stain deeper into the fibers.
