Guide
Yarn choice shapes how your rug feels, how long it lasts, how it takes color, and how much it costs. There's no single "best" — it depends on your budget and what the rug is for. Here's how the main options compare and how to get the strand count right.
| Yarn | Feel & durability | Notes |
|---|---|---|
| Wool | Soft, resilient, naturally stain- and flame-resistant; the premium choice | Expensive; springs back beautifully and ages well |
| Acrylic | Affordable, bright colors, easy to source | Great for learning and decorative rugs; less resilient underfoot over years |
| Wool/acrylic blend | A middle ground — much of wool's feel at lower cost | A popular practical choice for functional rugs |
| Cotton | Matte, absorbent, softer sheen | Nice for accents; less bouncy pile |
For a first rug, inexpensive acrylic lets you learn without worrying about wasting costly wool. For a rug you'll actually live on for years, wool or a wool blend is worth the money.

Practising your first piece? Look for bulky acrylic rug yarn in bright colors. For a keeper you'll walk on for years, step up to 100% wool rug yarn for its resilience and premium feel.
Cost is a real factor, and it's worth pricing per cone before you commit. As a rough anchor, tufting supplier Tuft Supplies lists 100% New Zealand wool at around €17.50 for a 500 g cone versus soft acrylic at roughly €13.90 for a 400 g cone — so wool runs meaningfully more per gram, and because a rug can easily swallow a couple of kilos, that gap adds up across a whole project. Learning on acrylic and saving wool for the piece you'll keep is a sensible way to spend.
Yarn is graded by thickness. The Craft Yarn Council standard weight system runs from category 0 (Lace) up to category 7 (Jumbo), and rug yarn lives near the heavy end — the council lists "Rug" as a typical use for its category 5, "Bulky." But you rarely feed a single bulky strand into a gun. Because tufting machines are built around a target thickness at the needle, most tufters combine several thinner strands to reach it, which is why a "2 or 3 strands of worsted" setup is so common. That approach also unlocks color blending, which a single fat yarn can't do.
Tufting guns are designed for a specific total yarn thickness feeding through the needle. Most use several thinner strands held together rather than one thick yarn, because combining strands lets you blend colors and fine-tune the thickness. If your yarn is thin, you run more strands; if it's chunky, fewer. Too thick and the gun jams; too thin and you get sparse, weak pile that shows the backing.
Getting this right is guesswork by hand, so our calculator includes a needle-to-yarn guide that suggests how many strands to run for common yarn weights — and its per-color yardage estimate tells you how much of each to buy.
A concrete example: many beginners on a cut-pile machine run two strands of worsted-weight (category 4) wool held together to get a dense, backing-hiding pile. Switch to a thinner fingering yarn and you might need four or five strands to fill the same needle; switch to a chunky category-5 yarn and one or two may be plenty. The target is the same finished thickness — you just reach it with a different count. Whatever you land on, note it down, because that strand count becomes the baseline for every color in the rug and for your yardage math.
Fiber choice also shapes how a finished rug lives with you. Wool sheds a little at first but settles, resists crushing, and tends to hide dirt; a quality wool rug can be gently spot-cleaned and lasts for years. Acrylic won't felt or shrink and takes vivid dye well, but the pile can flatten sooner under heavy foot traffic. Cotton absorbs moisture and dye readily, which is why it's better suited to accents and wall pieces than to a rug that has to shrug off spills. None of this makes one fiber "wrong" — it just means matching the yarn to how the rug will actually be used pays off long after the tufting is done.
| If the rug is… | Reach for | Why |
|---|---|---|
| Your first practice piece | Acrylic | Cheap enough to make mistakes on; bright colors |
| A floor rug you'll walk on for years | Wool or wool blend | Resilient pile that springs back; naturally more stain- and flame-resistant |
| A wall hanging or décor piece | Acrylic or cotton | Durability underfoot doesn't matter; color and texture do |
| Fine detail or matte accents | Cotton | Crisp, low-sheen definition in small areas |
| A balance of feel and budget | Wool/acrylic blend | Much of wool's hand at a lower price point |
Is wool or acrylic better for tufting? Neither is "best." Wool is more resilient and feels premium underfoot, so it suits floor rugs you'll keep; acrylic is cheaper and brighter, ideal for learning and for décor pieces.
How many strands should I run? Enough to match your gun's target thickness — often two strands of worsted for a cut-pile machine, more for finer yarn. Keep the count identical across every color.
Can I blend colors? Yes. Combining two close shades in one strand bundle creates a custom heather no single skein gives you.
