How to Crochet a Round T-Shirt Yarn Rug: A Complete Step-by-Step Guide

There is something deeply satisfying about transforming old t-shirts into something beautiful and functional for your home. A round t-shirt yarn rug is exactly that kind of project — one that combines sustainability, creativity, and practicality into a single stunning piece. Whether you are a seasoned crocheter or someone just getting comfortable with a hook, this guide will walk you through everything you need to know to create a gorgeous round rug from t-shirt yarn that you will be proud to display in any room of your home.

What Is T-Shirt Yarn and Why Is It Perfect for Rugs?

T-shirt yarn, often called “tarn” in the crafting community, is a stretchy, thick yarn made by cutting old t-shirts into long strips and rolling them into a continuous strand. The result is a chunky, flexible material that is soft underfoot, durable, and wonderfully eco-friendly. You can make your own at home from old cotton t-shirts, or you can purchase commercially made t-shirt yarn in a wide range of colors and weights from craft stores and online retailers.

What makes t-shirt yarn ideal for rug-making is its natural durability and thickness. Cotton fabric holds up beautifully to foot traffic, resists staining relatively well, and can typically be tossed into the washing machine when it needs freshening up. Because t-shirt yarn is so chunky, projects work up quickly, making it perfect for anyone who wants to see results fast without sacrificing quality.

A round shape is one of the most popular formats for handmade rugs because it softens a room, works well in front of doors, beside beds, under coffee tables, and in bathrooms or kitchens. The circular construction also makes it an ideal teaching project — once you learn how to increase properly to keep your circle flat, you can apply that knowledge to any size or variation you choose.

Gathering Your Materials

Before you sit down to crochet, you will want to gather everything you need. There is nothing more frustrating than getting into the rhythm of a project and discovering you are missing something essential.

For a round t-shirt yarn rug with a finished diameter of approximately 24 to 30 inches, you will need the following supplies. You will need roughly 300 to 500 yards of t-shirt yarn, depending on your desired finished size. For a larger rug closer to 36 inches or more, plan on 600 to 800 yards. You will also need a large crochet hook — a size 10mm to 15mm hook works beautifully with most t-shirt yarns. If the yarn you are using is especially thick or you prefer a looser, more flexible fabric, go up to a 20mm hook. A pair of scissors will be necessary, along with a tapestry needle or large blunt needle for weaving in your ends at the finish. Optional but helpful are stitch markers, which help you track where each round begins and ends.

If you are making your own t-shirt yarn from old shirts, you will need a collection of cotton t-shirts. Jersey knit is the most commonly used fabric because it curls in on itself when cut, creating that characteristic rounded strand. Avoid shirts with side seams if possible, or cut around them. A cutting mat and rotary cutter will make the job faster, though a good pair of fabric scissors works just as well.

How to Make Your Own T-Shirt Yarn

If you have a pile of old t-shirts and you would like to use them rather than purchasing commercially made yarn, making your own tarn is a straightforward process and a fantastic way to reduce textile waste.

Start by laying your t-shirt flat and cutting off the bottom hem. Then cut off the top portion of the shirt just below the armpits, so you are left with a tube of fabric. Fold this tube in half lengthwise so that both side edges line up. Starting from one folded edge, cut strips about one inch wide, stopping about an inch before you reach the other edge. Do not cut all the way through. You will end up with what looks like a fringe connected along one edge.

Open the tube and lay it flat on your work surface. Now, beginning at the top of your cuts, angle your scissors diagonally from the end of one strip to the beginning of the next, cutting across the connecting inch of fabric. This creates one long, continuous spiral of fabric. As you pull the strip, it will naturally curl in on itself, forming the rounded shape typical of t-shirt yarn. Wind it into a ball as you go.

One adult-sized t-shirt typically yields around 25 to 40 yards of yarn, depending on how wide you cut your strips and the size of the shirt. Wider strips create a bulkier yarn and work up more quickly; thinner strips create a finer, more flexible strand that is better suited to smaller hooks and more detailed work.

Understanding the Basic Crochet Stitches You Will Need

If you are relatively new to crochet, do not be intimidated. A round t-shirt yarn rug primarily uses just a few basic stitches. The main ones you will use are the magic ring (also called a magic circle), the chain stitch, the single crochet, and the slip stitch.

The magic ring is the preferred starting point for any crocheted circle because it allows you to pull the center hole completely closed. To make one, wrap the yarn around your index and middle fingers twice, insert your hook through both loops, pull up a loop of working yarn, and chain one to secure it. You can then work your first round of stitches into the ring before pulling the tail to close the hole.

Single crochet is the foundational stitch of this project. It is a short, dense stitch that creates a firm, sturdy fabric — exactly what you want in a rug. Insert your hook into the stitch, pull up a loop, and then pull through both loops on your hook. That is one single crochet.

The slip stitch is used at the end of each round to join the round closed. Insert your hook into the first stitch of the round, pull the yarn through both the stitch and the loop on your hook in one motion, and you have completed the join.

The Pattern: Crocheting a Round T-Shirt Yarn Rug

Now comes the exciting part. The following pattern creates a flat, round rug using single crochet stitches and a standard increase formula that keeps the circle lying flat rather than cupping or ruffling.

The key to a flat crochet circle is increasing the correct number of stitches per round. For single crochet, you need to add approximately 6 stitches per round. This is because the circumference of a circle grows proportionally to its radius, and 6 increases per round matches that mathematical progression beautifully in single crochet.

Starting the Rug

Begin with a magic ring. Into the ring, work 6 single crochets. Pull the tail to close the center hole. Slip stitch into the first single crochet to join the round. You now have 6 stitches in round 1.

Round 2: Work 2 single crochets into each stitch around. You will have 12 stitches total. Join with a slip stitch.

Round 3: Work 2 single crochets into the first stitch, then 1 single crochet into the next stitch. Repeat this sequence around the entire round. You will have 18 stitches.

Round 4: Work 2 single crochets into the first stitch, then 1 single crochet into each of the next 2 stitches. Repeat around. You will have 24 stitches.

Round 5: Work 2 single crochets into the first stitch, then 1 single crochet into each of the next 3 stitches. Repeat around. You will have 30 stitches.

Continue in this pattern, adding one additional plain single crochet stitch between each increase point with every new round. Round 6 will have an increase followed by 4 plain stitches, giving you 36 total. Round 7 will have an increase followed by 5 plain stitches, giving you 42 total. Each round adds 6 stitches to your total count.

Keep working in this manner until your rug reaches the size you want. A 24-inch rug will typically require about 16 to 18 rounds, while a 30-inch rug will require closer to 22 to 24 rounds. The exact round count will depend on your hook size, tension, and the thickness of your yarn.

Changing Colors for a More Decorative Look

One of the most enjoyable aspects of crocheting a round rug from t-shirt yarn is the ability to create beautiful color patterns. Stripes are the simplest and most effective design choice. Because you are working in rounds, each round creates a natural stripe, and switching colors between rounds requires almost no extra skill.

To change colors, work the last single crochet of a round until you have two loops remaining on your hook. At this point, instead of pulling through with the current color, drop it and pull through with your new color. Continue crocheting with the new color. You can carry the old color along the edge of your work by crocheting over it, or you can cut it and weave in the ends later.

For a more artistic result, try working two or three rounds in one color, then switching. Alternating between neutral tones like cream or grey and bold colors like mustard yellow, terracotta, or navy creates a rug with enormous visual impact. Gradient effects, where you gradually transition from one color family to another across many rounds, can make your rug look almost like a piece of woven art.

Tension and Keeping Your Rug Flat

The most common challenge beginners face when crocheting a round rug is keeping the finished piece flat. If your rug is cupping upward into a bowl shape, it means you are not increasing enough — your stitch count is too low. If your rug is ruffling and refusing to lie flat, you are increasing too much — your stitch count is too high.

The solution in both cases is simple. If the rug cups, add an extra increase stitch on the next round. If it ruffles, skip an increase stitch on the next round. Because t-shirt yarn is so forgiving and stretchy, minor imperfections will often block out beautifully when you wet the rug, press it flat, and allow it to dry.

Your tension — how tightly or loosely you hold the yarn as you work — also plays a significant role. T-shirt yarn is most enjoyable to work with when you hold it comfortably without gripping too tightly. A relaxed tension creates a softer, more flexible fabric. A tight tension produces a stiffer, firmer rug. Neither is wrong; it simply depends on your preference and intended use.

Finishing Your Rug

Once your rug has reached the desired size, it is time to finish it off. At the end of your final round, cut the yarn leaving a tail of about 6 to 8 inches. Pull this tail through the last loop on your hook and tug firmly to secure it. Thread the tail onto your tapestry needle and weave it through several stitches on the wrong side of the rug to secure it invisibly. Repeat with any other yarn tails from color changes throughout the project.

If you want to add a border, one or two rounds of single crochet around the outer edge in a contrasting color can give your rug a polished, finished look. Some makers also like to work a row of reverse single crochet, also known as crab stitch, along the outer edge for a slightly raised, decorative finish.

Once all ends are woven in, lay your rug on a flat surface and smooth it into shape with your hands. If it has any stubborn ruffles or uneven spots, mist it lightly with water from a spray bottle, press it flat, and allow it to dry completely before using it.

Caring for Your T-Shirt Yarn Rug

One of the most practical advantages of a t-shirt yarn rug is how easy it is to clean. Most t-shirt yarn rugs can be machine washed on a gentle cycle in cold water. Turn the rug over to the wrong side before washing and use a mild detergent. Avoid hot water and high-heat drying, as these can cause the cotton fibers to shrink and may distort the shape. Air drying flat is always the safest option, though a dryer on a low or air-only setting typically works well for most cotton t-shirt yarn rugs.

If your rug has a non-slip backing applied, check the backing material’s care instructions, as some latex-based non-slip sprays or mats are not machine washable.

Tips for Getting the Best Results

Using a hook that is slightly larger than what the yarn label recommends will create a more open, flexible fabric with better drape — ideal for a rug that needs to lie flat and absorb foot traffic comfortably.

If you are combining multiple different t-shirts to make your yarn, sort them by weight and thickness before you begin. Mixing very thin strips with very thick ones can create an uneven texture in the finished rug. Keeping your strip widths consistent throughout the project leads to a more uniform result.

Do not worry too much about perfection, especially if this is your first t-shirt yarn project. The handmade quality of a crocheted rug is part of its charm. Slight variations in thickness, minor imperfections in your increases, and the natural texture of recycled fabric all contribute to a piece that is uniquely yours.

Consider using a non-slip rug pad beneath your finished rug, especially in high-traffic areas like hallways or beside the bed. T-shirt yarn is naturally soft and somewhat grippy, but a rug pad will keep it securely in place and extend the life of the rug considerably.

Creative Variations to Try

Once you have mastered the basic round rug, there is a whole world of creative variations to explore. Try using a surface slip stitch technique to add decorative lines or patterns on top of your finished rug. Experiment with a tapestry crochet approach to incorporate two colors within a single round for more complex geometric or floral designs. Create a set of smaller coaster-sized circles using the same technique with thinner t-shirt yarn strips for a coordinated look throughout your home.

You can also scale the pattern up dramatically to create a large area rug, combining many balls of yarn across dozens of rounds. A rug measuring 48 to 60 inches across makes a stunning centerpiece for a living room, and the process is exactly the same — simply keep adding rounds until you reach your target size.

Final Thoughts

A crocheted round t-shirt yarn rug is one of those projects that manages to be beginner-friendly and endlessly creative at the same time. It is a meaningful way to use up fabric that might otherwise end up in a landfill, and the finished product is something genuinely beautiful and useful. Whether you choose a single color for a minimalist look or a vibrant rainbow of recycled t-shirt strips, your handmade rug will bring warmth and texture to any space it lives in.

The skills you build making this rug — controlling tension, working in rounds, making clean color changes — will carry over into dozens of other crochet projects. So gather your old t-shirts, grab a chunky hook, and enjoy the meditative rhythm of turning something worn-out and forgotten into something you will want to show everyone who walks through your door.
