How to Make a Spool Knitted Rug
There is something deeply satisfying about making a rug from scratch. It sits on your floor every day, underfoot and useful, and you made it with your own hands. Spool knitting is one of the oldest and most accessible fiber arts, and while many people associate it with small childhood projects — the little coils of I-cord that kids make on a plastic mushroom loom — it is actually a remarkably powerful technique for creating large, beautiful, durable rugs. With the right yarn, the right spool, and a bit of patience, you can transform almost any fiber into a floor covering that will last for years.
This guide will walk you through everything you need to know about making a spool knitted rug, from gathering your materials and understanding how spool knitting works, to finishing techniques, shaping options, and tips for making a rug that holds together beautifully over time.
What Is Spool Knitting?
Spool knitting — also called corking, French knitting, or knitting nancy — is a form of loom knitting that creates a continuous tube of knitted fabric called I-cord. The technique uses a cylinder with pegs or nails around the top opening. Yarn is looped around each peg, and then successive rows of loops are lifted over newer loops and off the pegs, producing a stretchy, rope-like cord that emerges from the bottom of the spool.
For rug-making purposes, this I-cord is then coiled, braided, or otherwise assembled into a flat textile. The resulting rug is dense, springy, and surprisingly strong. Because the cord is knitted rather than braided or woven, it has a natural give that makes it comfortable underfoot and forgiving during construction.
Traditional spool knitting tools were simple wooden spools with four nails hammered into the top. Today, you can buy purpose-built knitting spools, French knitting looms, or even large wooden cranking looms that produce I-cord far more quickly. For rug-sized projects, a crank-style loom or a spool with more pegs will save your hands a great deal of effort.
Choosing Your Materials
Yarn Selection
The material you use will determine the look, feel, durability, and washability of your finished rug. For floor use, you want something sturdy.
Cotton is a perennial favorite for rug making. It is washable, durable, holds its shape, and comes in a wide range of colors. T-shirt yarn (sometimes called zpagetti or jersey yarn) is made from recycled cotton knit fabric and produces wonderfully thick, cushy cord with an appealing texture. Cotton rope and macramé cord also work well.
Wool is traditional and beautiful. It is naturally resilient and somewhat moisture-resistant, and the slight felting that occurs with use actually helps the rug hold together better over time. If you plan to make a rug for a bathroom or kitchen, however, be aware that wool is not as forgiving of repeated washing as cotton.
Acrylic and acrylic blends are a practical choice if washability is a priority or if you are working on a tight budget. Look for bulky or super-bulky weight yarns to keep the project moving at a reasonable pace.
Upcycled fabric strips are another wonderful option. Old bed sheets, worn-out jeans, flannel shirts, and even plastic bags can be cut into strips and used as yarn. This approach is both economical and eco-conscious, and it gives your rug a unique character that store-bought materials cannot replicate.
How Much Yarn Do You Need?
This is the question that trips up most beginners, and the answer depends on the size of the rug, the thickness of the cord, and how tightly coiled or assembled the final piece will be. As a rough starting point, a small accent rug measuring about 20 by 30 inches will require approximately 500 to 700 yards of bulky yarn. A larger area rug measuring 3 by 5 feet can require anywhere from 2,000 to 4,000 yards depending on yarn weight. It is always better to buy more than you think you need — running short partway through is frustrating, and dye lots can vary.
Tools
Beyond yarn, you will need a spool or loom. For rug-making, the following options work well:
A large wooden spool with 4 to 8 pegs is the most traditional tool. It is slow but meditative, and it gives you excellent control over tension. These are widely available at craft stores or online.
A French knitting mill with a crank handle is dramatically faster and much kinder to your hands over the course of a large project. These typically have 4 pegs and produce consistent I-cord quickly. Many experienced rug makers consider this tool essential for any project larger than a small coaster.
A knitting board or large loom with more pegs will produce flat knitted fabric rather than I-cord, which can also be assembled into a rug, though the process is somewhat different.
In addition to your loom, you will need a hook or pick tool for lifting loops (usually included with the loom), a tapestry needle with a large eye, scissors, and straight pins or a corkboard for blocking if you want very precise shaping.
Setting Up and Making Your I-Cord
Getting Started on the Spool
Begin by threading your yarn through the center hole of the spool from the top, leaving a tail of about six inches hanging out the bottom. If your spool has a hole, this tail will eventually emerge from there as you knit; if not, simply hold it out of the way.
Wrap the yarn around each peg in turn, going in one direction — either all clockwise or all counterclockwise — until each peg has one loop around it. This is your foundation round.
The Basic Spool Knitting Stitch
Wrap the working yarn around the first peg again, above the existing loop. Using your hook, lift the bottom loop up and over the top loop, over the top of the peg, and off the peg entirely. The new loop is now the working loop on that peg. Move to the next peg and repeat: wrap the working yarn above the existing loop, then lift the lower loop over and off. Continue around all the pegs in order.
After the first few rounds, you will begin to feel and see the I-cord forming and emerging from the bottom of the spool. Gently tug on it from time to time to encourage even tension.
Maintaining Consistent Tension
Tension matters more in rug-making than in many other spool knitting projects, because the consistency of your I-cord directly affects how evenly the finished rug will lie flat. Try to wrap the working yarn with the same snugness each time. Too tight, and the cord will be stiff and difficult to coil; too loose, and the loops will be sloppy and uneven. With a little practice, you will find your natural rhythm.
Joining New Yarn
When you reach the end of a skein or want to change colors, leave a tail of about six inches on the old yarn. Lay the new yarn alongside it, overlapping by two or three pegs, and continue knitting with the new yarn. After you have worked several more rounds, weave in both tails using a tapestry needle, running each tail through the inside of the I-cord so they are hidden.
Assembling the Rug
Once you have made a substantial length of I-cord — and for a rug, you will need a great deal of it — you can begin assembling it into a rug. There are several methods for doing this, each producing a slightly different look.
Coiling and Sewing
This is the most common method and produces a classic oval or round rug. Begin by coiling the I-cord into a tight spiral. As you coil, use a tapestry needle and a length of the same yarn (or a durable thread in a matching color) to whipstitch adjacent rows of cord together. Run the needle through the side of one loop of cord, then through the corresponding loop on the neighboring cord, pulling snugly but not so tight that the rug puckers.
Start at the center with a small flat coil — a circle three or four rounds wide — then continue spiraling outward, stitching as you go. Check frequently that the rug is lying flat on a table or the floor. If it starts to cup or dome, your coiling is too tight; if it ruffles at the edges, your coiling is too loose. Adjust accordingly.
For an oval rug, start with a straight length of cord — perhaps ten or twelve inches long — and coil around that, rather than starting at a single center point. This initial straight section becomes the “spine” of the oval, and the curves at each end will be naturally rounded.
For a rectangular rug, you will stitch straight rows of I-cord side by side rather than coiling. Lay out lengths of cord parallel to each other and stitch them together along their sides. This approach requires more precise measurement but gives you clean, geometric edges.
Braiding
A second assembly method involves braiding three strands of I-cord together before sewing the braids into a rug. This produces a more textured, traditional look reminiscent of classic braided rugs. It also makes the rug noticeably thicker and heavier. If you go this route, make three times as much I-cord as you would otherwise need, then braid continuously and assemble the braids as you would the I-cord in the coiling method.
Crocheting Together
If you are a crocheter, you can use a large crochet hook to join adjacent rows of I-cord with a slip stitch rather than sewing them. This is faster than hand sewing and can create its own subtle texture at the seam lines. Use a hook size appropriate to your yarn weight — usually a size N or P hook for bulky I-cord.
Shaping and Sizing Your Rug
One of the great joys of making your own rug is complete control over the shape and dimensions. The most common shapes are round, oval, rectangular, and square, but there is no reason you cannot make a semicircular rug for in front of a sofa or a runner for a hallway.
For round rugs, consistent coiling is all you need. Measure the diameter periodically as you work to make sure you are reaching your target size.
For oval rugs, the final dimensions are determined by the length of your initial straight spine plus the width you build up by coiling. A ten-inch spine will give you an oval that is ten inches longer than it is wide. A longer spine makes a more elongated shape.
For rectangular rugs, plan the length first. Cut your I-cord into sections of the desired length (plus a few inches for finishing), then lay them out and sew or crochet them together. Use as many rows as you need to reach your target width.
Finishing Your Rug
Ending the I-Cord
When your rug has reached its desired size, you need to finish the end of the I-cord cleanly so it does not unravel. To do this, cut the working yarn leaving a tail of about eight inches. Thread the tail onto a tapestry needle. Lift each loop off its peg one at a time, running the tapestry needle through each loop before removing it from the peg. Once all loops are threaded onto the needle, pull the tail snugly to gather them closed, then run the needle back through the last inch or two of cord to secure.
Weaving In Ends
Go back through the finished rug and weave in any remaining yarn tails. Run each tail through the interior of the I-cord for at least two inches, then trim. Hiding ends inside the cord rather than at the surface gives a cleaner look.
Blocking
If your rug has any tendency to curl at the edges or is not lying perfectly flat, blocking will help. Wet the finished rug thoroughly, then lay it on a flat surface (a corkboard covered with a towel works well, as does a clean floor). Shape it to your desired dimensions, pin the edges if necessary, and allow it to dry completely. This can take anywhere from several hours to a full day depending on the thickness of the yarn. Blocking is especially effective with wool and cotton.
Adding a Non-Slip Backing
A spool knitted rug has some grip due to its texture, but for safety — especially on smooth floors — adding a non-slip backing is a smart idea. You can purchase non-slip rug pad material by the yard and cut it to the shape of your rug. Alternatively, apply dots or lines of silicone fabric paint (sometimes sold as puff paint) to the back of the rug and allow them to dry fully before use. This creates a textured surface that grips the floor without requiring a separate pad.
Care and Maintenance
One of the best things about a handmade rug is that, with proper care, it can last for decades. Most cotton and acrylic spool knitted rugs can be machine washed on a gentle cycle in cold water. Lay flat or hang to dry rather than using a dryer, as high heat can cause shrinkage and distort the shape. Wool rugs are best hand-washed or dry-cleaned.
Shake your rug out periodically to remove dust and debris. For rugs in high-traffic areas, rotate them occasionally so that wear is distributed evenly. If a section of stitching comes loose, repair it promptly before the looseness spreads.
Creative Variations to Try
Once you have mastered the basic spool knitted rug, a world of creative possibilities opens up. Here are a few directions worth exploring.
Color blocking involves making sections of I-cord in different colors and assembling them into a rug with distinct color zones. This can produce everything from subtle gradient effects to bold geometric patterns.
Striped rugs are easy to achieve by changing colors at regular intervals while making your I-cord. Plan your color sequence before you begin so the stripes appear where you want them when the cord is coiled or assembled.
Mixed textures come from using two different yarns held together as one — perhaps a smooth cotton and a fuzzy mohair blend, or a solid and a variegated yarn. The resulting I-cord will have an interesting, layered appearance.
Rag rugs use strips of old fabric in place of commercial yarn. This technique has a long history in folk traditions around the world and is a beautiful way to repurpose textiles that would otherwise be discarded. The result is a deeply personal rug that carries the history of the fabrics it contains.
Troubleshooting Common Problems
If your rug is not lying flat, the most common culprits are uneven tension in the I-cord, too-tight or too-loose coiling, or inconsistent stitching. Lay the rug flat and examine which areas are pulling or ruffling, then adjust your technique in those sections.
If your I-cord has dropped stitches or holes, check that you are consistently lifting the bottom loop over the top loop rather than dropping it back inside the peg. Dropped stitches can usually be repaired with a crochet hook by working the loose loop back up through the cord.
If the cord is very difficult to remove from the spool, your tension is too tight. Try wrapping the yarn a little more loosely around the pegs and see if that improves the flow.
Final Thoughts
Making a spool knitted rug is one of those projects that rewards patience and grows beautifully over time. The work is rhythmic and calming, the materials are endlessly adaptable, and the finished result is both functional and genuinely handsome. Whether you are making a small doormat from leftover yarn or a grand oval rug for your living room, the basic skills are the same — and once you have made one, you will very likely want to make another.
The rug you make will be yours in every sense: your yarn, your colors, your hours, your hands. And every time you walk across it, that will feel like exactly the right thing.
