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

There is something deeply satisfying about making a rug from scratch. It sits on your floor, it gets walked on every single day, and yet you made it with your own hands from materials that might otherwise have ended up in a donation bin or a landfill. A round T-shirt yarn rug is one of those projects that checks every box: it is beginner-friendly, budget-conscious, forgiving of mistakes, and the end result looks like something you would pay sixty dollars for in a home goods boutique.

This guide walks you through everything — from understanding what T-shirt yarn actually is, to choosing the right hook, to working the magic ring that starts every round rug, all the way to weaving in your ends and styling your finished piece. Whether you have been crocheting for years or you just picked up a hook for the first time, you are going to finish this project feeling proud.

What Is T-Shirt Yarn?

Before diving into the how, it helps to understand the material itself. T-shirt yarn, often called zpagetti, textile yarn, or fabric yarn, is exactly what it sounds like: yarn made from jersey cotton fabric, the same stretchy material used in everyday T-shirts. It comes in two forms.

The first is commercially produced T-shirt yarn, which you can buy by the cone or ball at craft stores and online retailers. It tends to be consistent in width, comes in hundreds of colors and prints, and is generally made from fabric offcuts produced during garment manufacturing. Buying this kind supports zero-waste production practices, which is a nice bonus.

The second is homemade T-shirt yarn, made by cutting up old T-shirts into continuous strips. If you have a drawer full of worn-out shirts you cannot bring yourself to throw away, this is a genuinely wonderful use for them. The process of making the yarn is a small project in itself, and it costs you nothing beyond a little time.

Both versions work beautifully for a round rug. Commercial yarn is more uniform, which makes for a flatter, more even rug. Homemade yarn has beautiful irregularities that give the finished piece a handmade, rustic character. Neither is better — it depends on the look you want.

Why Make a Round Rug?

Round rugs are incredibly versatile in home décor. They work in entryways, under coffee tables, beside beds, in nurseries, and in bathrooms. A round rug in a square room creates visual interest by breaking up the geometry of the space. It draws the eye toward a central point and makes a room feel warmer and more intentional.

From a crocheting standpoint, a round rug is also one of the most satisfying structures to make. You start with just a few stitches, and each round you work adds a visible ring of color and texture to the piece. You can watch it grow before your eyes in a way that rectangle projects simply do not offer. There is something almost meditative about working in rounds, with no seams, no turning, just an ever-expanding spiral.

Materials You Will Need

Getting your materials together before you start will make the process much smoother. Here is what you need.

For the yarn, plan on roughly 500 to 800 grams of T-shirt yarn for a medium rug measuring about 60 to 70 centimeters in diameter. If you want a larger rug in the 90 to 100 centimeter range, budget closer to 1.2 to 1.5 kilograms. You can absolutely use multiple colors — in fact, changing colors every few rounds is one of the most popular design choices for this type of rug.

For the hook, T-shirt yarn works best with a large crochet hook. A 10mm to 15mm hook is the standard range for this material, with 12mm being a sweet spot for many crafters. If you go smaller, the rug will be very stiff and dense. If you go larger, the stitches will be loose and the rug may not hold its shape well underfoot.

You will also want a yarn needle or tapestry needle with a large eye for weaving in ends, a tape measure or ruler, and scissors. A non-slip rug pad is optional but highly recommended once the rug is finished — T-shirt yarn rugs can slide on smooth flooring.

Choosing Your Colors

This is where you get to have fun. A single-color rug is elegant and modern. A two-color rug with alternating rounds creates a striped spiral effect that looks dynamic and bold. Using three or more colors opens up endless possibilities — you can go gradient by moving from light to dark, you can repeat a pattern of colors, or you can let it be entirely improvised based on whatever yarn you have on hand.

If you are new to working with color in crochet, a simple rule of thumb is to let one color dominate. Choose a main color that makes up at least fifty percent of the rug, and use accent colors for the remaining rounds. This keeps the finished piece from looking too busy or visually chaotic.

Neutral tones like cream, gray, beige, and black are perennially popular because they work in almost any room. But do not be afraid of color. A rug in deep terracotta, warm mustard, or forest green can completely anchor a room and become a genuine conversation piece.

Understanding the Basic Stitches

If you are new to crochet, you only need to know two stitches to make this rug: the slip stitch and the single crochet. That is it. No complex patterns, no special techniques.

The slip stitch is used to join rounds together. You insert your hook into a stitch, pull up a loop, and draw it directly through the loop already on your hook. It is the simplest stitch in crochet.

The single crochet is the main stitch of this rug. You insert your hook into a stitch, draw up a loop so you have two loops on your hook, then pull your yarn through both loops at once. One stitch made. It is firm, dense, and perfect for rug-making because it creates a tight fabric that holds up to foot traffic.

If you have never crocheted before, spending ten minutes practicing these two stitches on scrap yarn before you start the rug is well worth the time.

How to Make T-Shirt Yarn From Old Shirts

If you are making your own yarn, here is the process. Take a T-shirt and lay it flat. Cut off the bottom hem and the top portion including the arms and neckline, leaving just the main tube of fabric. Now cut the tube in a continuous spiral, moving from the bottom upward and cutting strips about two to three centimeters wide. The key is to cut at a slight diagonal so the strip stays connected as one long piece rather than becoming a series of rings.

Once you have your strip, stretch it gently. The fabric will curl in on itself, creating a rounded, rope-like strand of yarn. This is your T-shirt yarn. Wind it into a loose ball and you are ready to go.

One adult T-shirt typically yields about 25 to 40 meters of yarn depending on the size of the shirt and the width of your cuts. For a medium rug, plan on eight to twelve shirts.

Starting the Rug: The Magic Ring

Every round crochet project starts at the center, and the best way to begin is with a magic ring (also called a magic circle or adjustable ring). This technique allows you to close the center of your rug completely so there is no hole in the middle.

To make a magic ring, wrap the yarn around two fingers so the tail end crosses over the working yarn. Insert your hook under the first wrap and over the second, then pull the working yarn through to create a loop. Chain one to secure the ring — this chain does not count as a stitch. You are now ready to work your first round of single crochet stitches directly into the ring.

Work six single crochets into the magic ring for a standard starting point. Once you have worked all six, pull the tail end of the yarn to close the ring tightly. Join to the first stitch with a slip stitch to complete round one.

Working the Rounds

The key principle of making a flat circular crochet piece is consistent increasing. Every round, you add a certain number of stitches to keep the circle flat and prevent it from curling up into a bowl shape. The standard formula for single crochet rounds is to add six stitches per round.

Round 1: 6 single crochets in magic ring (6 stitches total).

Round 2: Work 2 single crochets in each stitch around (12 stitches total).

Round 3: Work 1 single crochet in the first stitch, then 2 single crochets in the next stitch. Repeat around (18 stitches total).

Round 4: Work 1 single crochet in each of the first 2 stitches, then 2 single crochets in the next stitch. Repeat around (24 stitches total).

You can see the pattern: each round, you add one more regular stitch before each increase. Keep this pattern going and your circle will lie perfectly flat.

For a rug measuring roughly 60 to 70 centimeters across, you will work approximately 12 to 15 rounds depending on the thickness of your yarn and the size of your hook. Use a tape measure to check the diameter as you go.

Changing Colors

To change colors at the end of a round, work the last single crochet of the round until you have two loops on your hook, then draw the new color through both loops to complete the stitch. The join of the round happens in the new color. Cut the old color, leaving a tail of about 15 centimeters to weave in later, and continue with the new color.

If you want clean, neat color joins, it helps to weave in your ends as you go rather than leaving them all to the end. Thread your yarn needle with the tail and weave it back and forth through several stitches of the matching color on the back of the rug, then trim the excess. Doing this every time you change colors takes only a minute and makes the final finishing step much less overwhelming.

Keeping the Rug Flat

Occasionally, even with correct increases, a rug may start to ruffle at the edges or cup in the middle. Here is how to troubleshoot both problems.

Ruffling at the edges means you are increasing too many stitches per round. Try working a round without any increases to let the circle catch up with itself, or switch to a slightly smaller hook for a few rounds.

Cupping in the middle means you are not increasing enough. Work an extra increase round, or add a few extra stitches at even intervals around the next round.

The good news is that T-shirt yarn is very forgiving. Even a slightly imperfect circle will block out beautifully once the rug is finished.

Finishing the Rug

When your rug has reached the desired size, finish off by cutting the yarn and pulling the tail through the last loop on your hook. Pull firmly to secure the stitch so it does not unravel.

Weave in any remaining ends using your yarn needle. Take your time here — a well-woven end will never come loose, even after repeated washing. Work the needle back and forth through at least five to six stitches, change direction, and weave back again before trimming.

If your rug is not lying completely flat, wet blocking can help. Dampen the rug with cool water (a spray bottle works well), shape it into a perfect circle on a flat surface, pin the edges if needed, and allow it to dry completely. The moisture relaxes the fibers and the rug will dry into whatever shape you have set.

Caring for Your T-Shirt Yarn Rug

One of the great things about T-shirt yarn is that it is almost always made from cotton, which is machine washable. For best results, wash your rug in cold water on a gentle cycle. Avoid high heat in the dryer — either tumble dry on low or lay the rug flat to air dry. High heat can cause the cotton fibers to shrink and the rug to change shape.

For everyday care, shake the rug out regularly to remove dirt and debris. Spot clean small stains immediately with a damp cloth and a mild detergent rather than waiting for wash day.

Design Variations to Try Next

Once you have made your first round T-shirt yarn rug, you will almost certainly want to make another. Here are a few directions to take your skills.

A striped rug with thin alternating rounds creates a candy-stripe effect that works wonderfully in a child’s bedroom or a bright kitchen. Using six or more colors and changing each round produces a rainbow spiral that is a cheerful statement piece. Working a few rounds in a chunky textured stitch like the half double crochet gives the surface of the rug a different feel underfoot and a slightly different visual texture.

You can also experiment with scale. A small version, about 30 centimeters across, makes a perfect pot holder or trivets for the kitchen. A very large version, 120 centimeters or more, becomes the kind of living room centerpiece that ties an entire room together.

Why This Project Is Worth Your Time

Learning to crochet a round T-shirt yarn rug is not just about acquiring a craft skill. It is about making something durable and beautiful from a material that might otherwise go to waste. It is about the quiet satisfaction of a repetitive, rhythmic task. It is about putting something on your floor and knowing that every stitch in it passed through your hands.

Handmade rugs have been part of domestic life across cultures for thousands of years. Modern T-shirt yarn simply brings that ancient practice into the present with materials we have on hand today. The result — practical, beautiful, personal — is as timeless as the craft itself.

Pick up your hook, pull out that ball of yarn, and start in the center. The rest takes care of itself, round by satisfying round.
