How to Make a Toothbrush Rag Rug: A Complete Step-by-Step Guide

There is something deeply satisfying about making something beautiful and functional out of materials that would otherwise be thrown away. Toothbrush rag rugs are one of the oldest and most beloved American folk crafts, and they are enjoying a well-deserved revival among people who love sustainable living, handmade home décor, and the meditative rhythm of working with their hands. If you have never made one before, you are in for a treat. This guide will walk you through everything you need to know — from gathering your materials to finishing your last knot — so you can create a durable, colorful, and completely unique rag rug for any room in your home.

What Is a Toothbrush Rag Rug?

Before diving into the how-to, it helps to understand what makes this style of rug different from other types of handmade rugs like braided, woven, or hooked rugs. A toothbrush rag rug is made using a large, blunt needle — traditionally fashioned from a repurposed toothbrush — to loop and interlock strips of fabric in a technique that resembles a form of hand-linking or hand-twining. The result is a tightly constructed, dense, reversible rug that holds up incredibly well to foot traffic and daily use.

The name comes from the original tool: crafters would take an old toothbrush, cut off the bristle head, file the end smooth, and drill or carve a large eye through which fabric strips could be threaded. Today, you can buy dedicated toothbrush rug needles, but many makers still enjoy the tradition of making their own tool.

These rugs have a wonderfully textured, slightly sculptural surface. Unlike a braided rug, which lies flat and smooth, a toothbrush rug has a looped, knotted quality that gives it real depth and visual interest. And because they are made entirely from recycled fabric, they are one of the most sustainable craft projects you can undertake.

Why Make a Toothbrush Rag Rug?

The reasons people fall in love with this craft are as varied as the rugs themselves. Here are just a few of the most compelling ones.

It is nearly free. The main material is fabric you already own — old t-shirts, worn-out jeans, outgrown clothing, worn bed sheets, or any other woven or knit material that has outlived its original purpose. If you do not have enough fabric on hand, thrift stores and fabric swaps are excellent sources.

It is eco-friendly. Instead of sending textiles to the landfill, you are giving them a second life as something beautiful and useful. Given that the fashion and textile industry is one of the largest contributors to global waste, every rag rug made is a small but meaningful act of environmental responsibility.

It is meditative and rewarding. The repetitive hand movements involved in toothbrush rug making have a calming, almost hypnotic quality that many crafters find deeply relaxing. It is a wonderful project to work on while listening to music, podcasts, or audiobooks.

The results are stunning. A finished toothbrush rag rug has a handmade character and warmth that no machine-made rug can replicate. Each one is genuinely one of a kind.

It is customizable. You choose the colors, the size, and the shape. Oval, round, rectangular — the form follows your vision and your fabric supply.

What You Will Need

Gathering your materials before you begin will make the process much smoother. Here is a complete list of what you need to make a toothbrush rag rug.

Fabric strips. This is your primary material. The most popular choices are old cotton t-shirts, denim, flannel, wool, and cotton bed sheets. T-shirt knit fabric is particularly popular because it stretches slightly and creates a soft, pliable strip that is easy to work with and produces a cushioned, comfortable rug. Plan to have far more fabric than you think you need — a medium-sized oval rug measuring roughly 24 by 36 inches can easily consume four to six large adult t-shirts or the equivalent in other fabric. Denser fabrics will use less yardage; thinner ones will use more.

Toothbrush needle. You can buy one online from a craft supplier, or you can make your own. To make one from a toothbrush, cut the head off just below where the bristles begin. Use a craft file or sandpaper to smooth the cut end into a rounded tip. Then carefully drill or carve a hole — the “eye” — through the handle about an inch from the blunt end. The eye needs to be large enough to thread a folded fabric strip through. A repurposed large plastic darning needle or a commercial rug needle will also work perfectly.

Scissors. A good, sharp pair is essential for cutting clean strips and trimming ends.

A rotary cutter and cutting mat (optional but helpful). If you are cutting a large quantity of fabric, a rotary cutter makes the process much faster and produces more uniform strips.

A ruler or seam gauge. For measuring consistent strip widths.

A crochet hook (optional). A large crochet hook can be helpful for pulling fabric loops through tight spots and for joining strips.

How to Prepare Your Fabric

Fabric preparation is one of the most important steps, and it is worth taking your time here. The quality of your strips has a direct impact on how the finished rug looks and feels.

Wash your fabric first. Before cutting anything, wash and dry all of your fabrics. This pre-shrinks them, removes any sizing or finishes, and ensures your finished rug will not shrink or bleed later.

Choose your strip width. For most toothbrush rug projects, strips cut between three-quarters of an inch and one and a half inches wide work well. Thinner strips create a finer, more delicate texture. Wider strips produce a chunkier, more rustic look and work up faster. For a first project, try one inch as a good middle ground.

Cut your strips. For woven fabrics like denim or cotton sheeting, cut straight across the grain of the fabric. Many people cut long continuous strips by cutting a spiral around the fabric — start cutting along one edge, then angle your cut inward so you spiral around the piece and end up with one long strip rather than many short ones.

For t-shirt knit fabric, you can cut continuous loops by laying the shirt flat and cutting horizontally across the body of the shirt, avoiding the seams. Each cut creates a loop. You can then stretch each loop gently and it will curl into a rounded cord-like strip that is perfect for rug making.

Join your strips. You will inevitably run out of one strip and need to join on a new one. The simplest method is a lark’s head knot join: fold the end of your new strip into a small loop, pass it through the end of your finishing strip, and pull the tail of the new strip through its own loop. Pull snug. This creates an inconspicuous join that disappears into the body of the rug.

Organize by color. If you are planning a rug with a specific color pattern, sort your strips into piles or wind them into loose balls before you begin. Having everything organized makes the work flow much more enjoyably.

How to Make a Toothbrush Rag Rug: Step by Step

Now for the heart of the project. The traditional toothbrush rag rug technique creates an oval rug, which is the easiest shape to start with. The oval begins with a center row — called the foundation row — and you build outward from there in concentric rings.

Step 1: Create the foundation row.

Take two strips of fabric, one in each hand. Fold them each in half to find the center, then tie them together at their centers with an overhand knot. This knot becomes the very center of your rug, and you will build everything out from it. The length of your foundation row determines the length of your finished rug. A longer foundation means a more elongated oval; a shorter foundation produces a rounder oval or even a circle if the foundation is just the central knot.

For a standard medium oval rug, you might work a foundation row of eight to ten inches before beginning to turn the corners.

Step 2: Work the foundation row.

Thread one of your fabric strips through the eye of your toothbrush needle. Working with the strip in the needle and a second strip held in your other hand, you will create a series of interlocking loops. Pass the needle through the loop of the second strip, draw the strip through, then pass the second strip through the loop just created. This interlocking motion — alternating which strip passes through which — is the fundamental stitch of toothbrush rug making. Keep the loops snug and even as you work.

Step 3: Turn the end and begin the second row.

When you reach the end of your foundation row, you need to turn the corner to begin building the oval shape. At the turning point, you will increase — that is, work additional stitches into the same spot — to allow the rug to curve without puckering or cupping. Most makers work two to three interlocking stitches at each end of the oval to create a smooth curve. With practice, you will develop a feel for how many increases are needed to keep your work lying flat.

Step 4: Continue working in rounds.

After turning both ends, you are now working in rounds — traveling along one long side of the oval, around one curved end, down the other long side, and around the other curved end. Continue the interlocking stitch around and around, increasing at the ends of the oval as needed to keep everything flat.

A good rule of thumb: if your rug starts to cup upward at the edges, you need more increases at the ends. If it starts to ruffle and ripple, you have too many increases and need to work some rounds without increasing at the curves.

Step 5: Add new strips as needed.

When one strip runs short, join on a new one using the lark’s head method described earlier, or simply tie the ends together and trim the tail to about half an inch. As you continue to work, these joins will be tucked into the body of the rug and become invisible.

Step 6: Continue until you reach your desired size.

Keep working outward, round by round, until your rug reaches the size you want. A small accent rug might measure 12 by 18 inches. A substantial area rug could be 30 by 48 inches or larger. The only limit is your fabric supply and your ambition.

How to Finish Your Toothbrush Rag Rug

Finishing is important — a properly secured edge will keep your rug from unraveling through years of use.

When you reach the final round, cut your working strips to leave about three inches of tail. Thread each tail through the eye of the needle and pass it through several of the nearby loops on the underside of the rug, essentially weaving it into the structure. Pull snug and trim any remaining excess. Repeat for the other tail. Some makers add a few stitches of sturdy thread in a matching color to secure the very last join, which is good practice for a rug that will see heavy use.

Tips for a Beautiful Finished Rug

A few hard-won insights from experienced toothbrush rug makers can save you a lot of frustration.

Keep your tension consistent. Uneven tension is the most common beginner mistake and produces a rug that cups, ripples, or has an irregular surface. Try to work each stitch with the same degree of firmness throughout.

Work in good light. It is easy to miss loops or make errors when you cannot see clearly what your hands are doing.

Block your rug when finished if needed. If your rug has any cupping or warping, try dampening it lightly and pressing it flat under heavy books or other weights while it dries. This can correct minor distortions.

Do not be afraid of imperfection. Especially in a first rug, minor variations in tension or shape are part of the handmade character. Future rugs will benefit from everything you learn in this one.

Caring for Your Toothbrush Rag Rug

One of the great practical advantages of these rugs is how easy they are to care for. Because they are made entirely from pre-washed fabric and contain no backing or batting, most toothbrush rag rugs can go straight into the washing machine on a gentle cycle with cold water. Lay flat or hang to dry to preserve the shape. Avoid high heat in the dryer, which can cause some fabrics to shrink unevenly.

For everyday maintenance, shake the rug outside to remove dust and debris. A quick vacuum on low suction will also keep it fresh between washings.

Color and Design Ideas

One of the most joyful aspects of making a toothbrush rag rug is the design freedom it offers. Here are some approaches worth considering.

A scrap rainbow rug uses every color and type of fabric you have, arranged randomly or in a rough spectrum from one end of the rug to the other. These rugs are cheerful, vibrant, and are a wonderful way to use up a truly mixed bag of scraps.

A two-color rug creates a clean, graphic look. Alternating two colors in every row produces a speckled or tweed effect. Working one color in the center and switching to another for the outer rows creates a bold border.

A tonal rug uses different shades and textures of a single color family for a sophisticated, harmonious result that works in almost any interior. Think ivory through caramel through dark brown using natural cotton and linen fabrics.

A denim rug, made entirely from cut-up jeans in various washes, is a perennial favorite that produces a sturdy, casual rug with beautiful tonal variation and impressive durability.

Making a Toothbrush Rug Needle from Scratch

If you would like to honor the full tradition of this craft, making your own needle adds another layer of satisfaction to the project. As mentioned earlier, the classic method uses an old toothbrush. Choose one with a long, straight handle. Use a fine-toothed saw or a craft knife to remove the head cleanly. File or sand the cut end to a smooth, rounded tip — no sharp edges that could snag your fabric. Then, using a small drill bit (around 3/16 inch works well for most fabric strips), carefully drill the eye about an inch from the blunt tip. Sand the eye smooth so there are no rough edges. Your needle is ready to use.

Hardwood dowels, large wooden spoons with the bowl removed, and even sturdy lengths of bamboo have all been used to make toothbrush rug needles by creative makers over the years.

A Living Tradition

Toothbrush rag rugs have been made in American homes for well over a century, and the craft has been passed down through generations as both a practical skill and a creative tradition. In the days before affordable manufactured goods, making rugs from worn-out clothing was a necessity. Today, it is a choice — and a particularly meaningful one, because it connects us to the ingenuity and resourcefulness of the people who came before us, while also producing something genuinely lovely for our own homes.

Whether you make a small mat for your entryway or an ambitious room-sized rug for your living room, you will find that toothbrush rag rug making is one of those crafts that repays every hour you put into it many times over. The process itself is enjoyable. The finished object is durable, beautiful, and completely your own. And every time someone admires it and you tell them it was made from old t-shirts and a modified toothbrush, you will enjoy the look on their face.

Gather your scraps, sharpen your scissors, and get started. Your first rug is waiting to be made.
