Best yarn for rug tufting – wool, acrylic and cotton compared

Wool vs acrylic vs cotton: quick comparison

For rugs that will see regular foot traffic or are intended to last for years, wool is generally the better choice because of its durability, natural bounce, and soft, premium feel. Acrylic yarn is often better suited to wall art, decorative rugs, and beginner projects, especially when affordability, easy carving, and a wide range of colors are priorities. Cotton sits in between: dense and natural-looking, but with the least elasticity. That said, a well-made acrylic rug with a good layer of tufting glue and a secondary backing cloth can still work well on the floor in low-traffic rooms.

Wool yarn for tufting

• Durability: Wool is a popular choice for high-quality floor rugs because its fibers naturally recover from compression and hold up well against crushing, matting, and frequent foot traffic. If lifespan is your main concern, our article on how long tufted rugs last covers what else affects it.
• Feel: Its natural crimp gives the pile a soft, springy texture and creates a comfortable, luxurious surface underfoot.
• Safety: Wool fibers are naturally resistant to ignition, making them a more fire-resistant option than many synthetic fibers.
• Drawbacks: Wool yarn is typically more expensive, may be available in fewer colors than acrylic, and can shed some fibers when a new rug is first used.

Acrylic yarn for tufting

Yes, acrylic yarn can be used for tufting, and it is especially popular among beginners. It is generally affordable, available in a large selection of vibrant colors, and easy to feed through a tufting gun and trim when finishing a rug.

The key distinction is between standard craft acrylic (knitting yarn from a craft store) and tufting acrylic, sometimes marketed as synthetic wool. Tufting acrylic is thicker and denser, so it fills the needle as a single or double strand and holds its shape in the pile better. The tufting yarn we sell at Tufty is this type: 100 % acrylic, 100 g per ball, 147 m long, 4.5–5 mm thick and made in Czechia. Craft acrylic works, but expect a softer, less resilient surface.

• Color selection: One of its main advantages is the extensive selection of bold, bright, and vibrant colors.
• Maintenance: Acrylic is resistant to moth damage and is commonly considered a practical synthetic option for decorative projects.
• Ideal for wall art and decorative rugs: Standard craft acrylic is less resilient than wool, which makes it a good option for tufted wall hangings, decorative pieces, and pillows.
• Acrylic on the floor: An acrylic rug can be used on the floor in bedrooms or other low-traffic areas. The glue layer and secondary backing do most of the structural work of holding the pile in place; what acrylic cannot match is wool's ability to spring back after years of being walked on.
• Choose a suitable yarn weight: Very thin, single-ply knitting yarn will not create a dense pile on its own. Thicker multi-ply acrylic yarns, such as chunky or worsted weights, generally work better. Strand counts are covered in the thickness section below.
• Be careful with high temperatures: Because acrylic is a synthetic fiber, it can soften or melt when exposed to excessive heat. Finished acrylic rugs should be kept away from heaters, open flames, and other strong heat sources.

Polyester yarn

Polyester is the other common synthetic tufting yarn. It behaves much like tufting acrylic in the gun and in the pile, but holds color better in sunlight, absorbs almost no moisture and dries fast, which makes it a sensible choice for rugs in bright rooms or near entrances. Its drawbacks are the same as acrylic's: it flattens sooner than wool under heavy traffic and is sensitive to heat. If you find a polyester yarn in the same 4–5 mm thickness range, treat it exactly like tufting acrylic when choosing strand counts.

Cotton yarn for tufting

Yes, cotton yarn can be used for tufting, although it does not have the same elasticity and durability as wool or acrylic. Cotton is generally better suited to wall hangings, decorative projects, and loop-pile designs than rugs exposed to heavy foot traffic. If you are deciding between loop and cut pile for a cotton piece, our comparison of cut pile vs loop pile explains the trade-offs.

• Structure and durability: Cotton has limited elasticity, which can make it more difficult to feed consistently through a tufting gun. Compared with more resilient fibers, cotton may also lose its shape or compress faster when used in high-traffic floor rugs.
• Texture and finishing: Cotton creates a dense, natural-looking surface with a soft matte appearance. However, cut-pile cotton can be more difficult to carve and shear cleanly with a rug trimmer, which may make achieving a perfectly smooth finish more challenging.
• Wear on the gun: Cotton, including organic cotton, is harder on the scissors of a cut-pile tufting gun than acrylic or wool. It works, but expect to sharpen or replace the blades sooner if you tuft a lot of it.
• Feeding tip: Because cotton yarn is relatively firm and less flexible, choose a thicker yarn where possible and consider feeding two strands through the gun at once. This produces a fuller pile and reduces the chance of the yarn slipping out of the backing cloth.

Can regular knitting yarn be used with a tufting gun

Yes, regular knitting yarn can be used with a tufting gun, as long as the yarn has a suitable thickness and feeds smoothly through the machine. Yarn around 3–4 mm thick, such as medium or worsted weight, generally works well. What matters more than the label on the ball is consistent thickness along the whole length: uneven yarn causes bald spots and a restless pile.

Key tips for using regular yarn with a tufting gun

• Choose the right material for the use: Wool for floor rugs that need to last, acrylic or cotton for wall hangings, decorative rugs, and cushions. The comparison table at the top of this article summarizes the differences.
• Avoid very thin or slippery yarn: Fine yarns and smooth fibers such as silk or bamboo can be difficult to control with a tufting gun. They may not grip the backing cloth properly and can lead to inconsistent tufting.
• Feed the yarn evenly: Cones on a stand give the smoothest feed. Balls and skeins also work if you keep them from bouncing: drop the ball into a bucket or box, or clamp a yarn winder to the table so a 100 g ball unwinds without jerking. Uneven tension is a common cause of skipped stitches and jams, as covered in our guide on how to thread a tufting gun.

Yarns to avoid

• Novelty yarns – bouclé, chenille, eyelash and other textured yarns snag in the needle and do not form an even pile.
• Super-bulky yarn over roughly 6 mm will not pass through the 3–5 mm needle opening of a standard tufting gun.
• Loosely spun single-ply yarn frays and breaks as the needle pushes it through the cloth.
• Yarn with wire or metallic thread dulls the cut-pile blades quickly and can jam the gun.

What yarn thickness works best with a tufting gun

For most standard tufting guns, medium to bulky yarn (Worsted to Chunky / Weight 4–5) is usually the best choice. A single thin strand may not stay securely in the backing cloth and can produce a sparse-looking rug. The goal is to use enough yarn to achieve a full, plush surface without overfilling or jamming the tufting gun.

Here is how different yarn weights typically perform and how many strands to feed at once:

• Bulky / Chunky yarn (Weight 5): Usually works as a single strand, two at most. Yarn in the range of roughly 1000–1500 m/kg fills the needle well, provided it moves freely through the tufting gun's 3–5 mm needle opening without catching or fraying. Tufty's 100 g tufting yarn (147 m per ball) falls into this category.
• Aran / Worsted and DK yarn (Weight 3–4): Combine two or three strands. Besides increasing pile density, this lets you mix colors and create richer textures or marled effects.
• Very fine yarn (Lace / Fingering): Generally unsuitable as a single strand because it will not remain securely held in the primary backing. If you want to tuft with very thin yarn, combine three or four strands at once.

If you are still getting gaps, check the fabric tension before changing yarn: loose backing is the most common cause of yarn falling out. The guide lines printed on the cloth should run perfectly straight once it is stretched; a curved line means that spot needs tightening. The cloth itself rarely needs changing for a different yarn: a standard monk's cloth or polyester primary cloth holds every yarn type above, and the one combination that tends to pull out – thin yarn as a single strand – is fixed with more strands, not a different fabric. For the differences between the two cloths, see what monk's cloth is and which fabrics you can use for tufting.

How much yarn do I need for a tufted rug

For a typical cut-pile rug, count on roughly 1.6–2.4 kg of yarn per square meter, depending on pile height, how tightly you place your rows, and how many strands you feed at once. As a quick guide, a 50 × 50 cm piece needs around 0.4–0.6 kg and a 60 × 90 cm rug (0.54 m²) around 0.9–1.3 kg. Calculate each color separately and buy about 20% more than your estimate: matching the same dye lot later is often impossible, and the reserve covers test sections, trimming, and mistakes.
