The Best Yarn for Tufting: Acrylic, Wool, Cotton and Blends Compared
The yarn you choose decides more about a finished rug than almost anything else: how soft it feels, how well it survives being walked on, how crisp the colour edges look, and what it costs. This guide compares the common choices without pushing any one shop or brand.
What makes a yarn good for tufting
A tufting gun pushes yarn through woven backing cloth at speed, and cut-pile guns slice it every stitch. A good tufting yarn has to survive that and then look good standing upright. Look for:
- A smooth, even strand. Lumps, slubs and loose fibres catch in the needle and the feed.
- Some spring. Pile that bounces back holds its height; pile that does not goes flat in the first month on a floor.
- Colourfastness. Glue, water and sunlight should not move the dye.
- A thickness that suits your gun. Together, your strands should fill the needle without forcing it.
The main fibres, compared
| Yarn | Feel | Durability on a floor | Cost | Best for |
|---|---|---|---|---|
| Acrylic | Soft, slightly synthetic | Fair; flattens with heavy traffic | Lowest | First rugs, wall pieces, bright colours |
| Wool | Dense, warm, springy | Excellent; recovers and hides dirt | Highest | Floor rugs, commissions, heirloom pieces |
| Wool blend | Close to wool | Good | Middle | Floor rugs on a budget |
| Cotton | Matte, soft | Poor in cut pile; flattens and frays | Low to middle | Loop-pile wall pieces, mats |
| Polyester / recycled | Varies widely | Varies | Low | Experiments, sustainability-focused work |
Acrylic
Acrylic is where almost everyone starts, for good reason. It is inexpensive, light, easy to find in hundreds of saturated colours, and most tufting yarn sold as such is acrylic. It feeds well and cuts cleanly.
The trade-offs: acrylic pile crushes more than wool under furniture and foot traffic, it can pill, and it melts rather than smoulders near heat. For a wall hanging, a bedroom mat or a decorative piece, none of that matters. For a hallway runner, it does.
Wool
Wool is the traditional rug fibre. Each fibre has a natural crimp, so pile springs back after it is stepped on, and the lanolin and scale structure make it slow to soil. It takes dye with a depth that acrylic struggles to match, and it is naturally flame-resistant.
It costs more per kilo and is heavier per square metre, so a wool rug can cost two to three times as much in yarn as the same rug in acrylic. If you sell commissions, that difference belongs in the quote. Rug wool is usually thicker than acrylic tufting yarn, so you run fewer strands, often one or two.
Wool blends
Blends of wool with acrylic or nylon sit in the middle. They keep much of wool's spring and soil resistance at a lower price, and the synthetic part adds strength. A blend with at least half wool is a sensible default for a floor rug where pure wool is out of budget.
Cotton
Cotton is soft and takes colour well, but it has almost no spring. In cut pile it flattens quickly and the cut ends fray. It works better in loop pile, where the loops hold their shape, and in pieces that hang on a wall. If a client asks for cotton for a floor rug, steer them toward wool or a blend.
Polyester, recycled and novelty yarns
Recycled polyester and mill-end yarns can be very cheap and are a good way to practise. Quality varies batch to batch, so test a square first. Fuzzy, boucle, mohair, chenille and other textured yarns usually jam the needle or snag in the feed. Save them for hand-finished accents.
How many strands to run
Most tufting guns are made for several strands fed together. The goal is enough yarn to cover the backing so no cloth shows between lines, without forcing the needle.
- Thin acrylic tufting yarn: three or four strands is common.
- Medium acrylic or blends: two or three strands.
- Thick rug wool: one or two strands.
Run a test line on the edge of your frame. If you see backing between the tufts, add a strand or run your lines closer. If the gun labours or the yarn jams, remove one. Every extra strand adds the full weight of another layer, so it also changes how much yarn you need.
Cost per square metre
Price per kilo is only half the story; weight per square metre is the other half. Using the figures Loopi's calculator works with at 18 mm cut pile:
- Three strands of acrylic use about 2.7 kg/m². At €12 per kilo, that is about €32 of yarn per square metre.
- One strand of rug wool uses about 2.5 kg/m². At €30 per kilo, that is about €75 per square metre.
Your prices will differ; the point is to compare per square metre rather than per cone. Put your own price per kilo into the yarn calculator and it does this for every colour in the design.
Matching colours across yarns
Different fibres take dye differently. A red acrylic and a red wool from the same palette card can look like different colours side by side, and acrylic often reads brighter under daylight. If one rug mixes fibres, tuft a small test with both before committing. When you design on screen, use the colours you actually own: Loopi's yarn shelf keeps your real yarns with their colours and prices, so the preview matches what you will tuft.
Frequently asked questions
What is the best yarn for a beginner?
Acrylic tufting yarn. It is cheap, forgiving and available in every colour, so mistakes cost little while you learn the gun.
Can I use knitting yarn for tufting?
Often, yes, if it is smooth and the right thickness. Plain acrylic or wool knitting yarns work when fed in the right number of strands. Avoid very chunky, loosely spun or fuzzy knitting yarns, which jam.
Is wool worth it for a floor rug?
For a rug that will be walked on every day, yes. Wool recovers from crushing and hides dirt far better than acrylic, so the rug looks new for longer.
Why does my pile look thin and patchy?
Usually too few strands for the yarn's thickness, or lines spaced too far apart. Add a strand or run your lines closer, and see tufting gun troubleshooting if the gun is skipping.
Does the yarn change the price I should charge?
Yes. Wool can double the material cost of a rug. Work the yarn cost into your quote rather than a flat per-square-foot rate; see how to price a tufted rug.
