Have you ever made a lovely crochet or knitting project that started to pill after a few wears or washes? Annoying, after all the hours you put in. Luckily some yarns pill much less than others, and a few habits keep your work looking good for longer. Below you'll find five low-pilling yarns and how to prevent pilling.
Why do some yarns pill and others don't?
Pills form when loose fiber ends work their way out of the yarn through rubbing, washing and wearing, and then tangle into little balls. Three things decide how much a yarn pills:
- Fiber length: short fibers have more loose ends and pill faster. Long fibers stay anchored in the yarn.
- Twist: tightly spun and plied yarns hold their fibers better than loosely spun, lofty yarns.
- Fiber strength: this one surprises people. Weak fibers like wool pill, but the pills often break off. Strong synthetic fibers like acrylic and polyester can pill just as much, and the pills stay attached because the fiber doesn't break.
So "synthetic" does not automatically mean "doesn't pill". Quality and construction matter more than the fiber name. Not sure which yarn fits your project? Our guide to the best yarn for crochet puts cotton, acrylic, wool, bamboo and linen side by side.
Quick checklist: is this yarn likely to pill?
- Does it feel smooth and look shiny, or soft, fuzzy and airy?
- Is it plied (several strands twisted together) and firmly twisted?
- Rub a strand between your fingers for a while: does fuzz appear quickly?
- Does the label say "anti-pill" or "superwash"? That helps, but it's no guarantee.
5 yarns that pill the least
1. Mercerized cotton
Cotton is naturally sturdy. Mercerized cotton has had an extra treatment that makes it smoother, stronger and shinier, so fewer fiber ends work their way out. It's a good pick for clothes, accessories and amigurumi. Try a light summer top or a bag in mercerized cotton: they stay neat for a long time.
Regular smooth cotton also pills little. Durable Coral is 100% cotton and suits amigurumi, garments and homeware.
2. Linen
Linen is one of the strongest natural fibers, with long fibers that hardly pill. It doesn't stretch out and gets softer over time. A good choice for bags, placemats and summer clothes. Read more in our guide to linen yarn.
3. Silk and smooth plant-fiber blends
Silk is a long, smooth filament, so it rarely pills. You'll often find it blended with cotton, linen or wool to add sheen and strength. Bamboo yarn, on the other hand, is usually viscose made from bamboo: smooth and cool, but it can wear and fuzz on spots that see a lot of friction.
4. Tightly spun, long-staple wool
Wool has a reputation for pilling, but not every wool is the same. Wools with long fibers (such as Bluefaced Leicester or many sock yarns) that are tightly plied stay surprisingly smooth. Very soft, loosely spun merino is lovely to wear but is one of the faster pillers. Tip: wash wool with a wool wash and dry it flat; see how to wash wool.
5. Good-quality "anti-pill" acrylic
Some acrylic yarns are made to resist pilling, for example with longer fibers or a tighter construction. They are easy-care and work well for blankets and kids' items. Cheap, loosely spun acrylic, on the other hand, pills quickly. Microfiber says something about how fine the fibers are, not whether the yarn pills, so always look at the specific yarn and follow the care label. Blankets in a soft acrylic are cozy; just don't expect them to stay completely pill-free.
Low-pilling yarns compared
| Yarn | Pilling | Good for |
|---|---|---|
| Mercerized cotton | Very low | Tops, bags, amigurumi |
| Linen | Very low | Bags, placemats, summer wear |
| Silk blends | Low | Shawls, garments |
| Long-staple, tightly plied wool | Low to medium | Sweaters, socks, hats |
| Anti-pill acrylic | Low to medium (depends on quality) | Blankets, kids' items |
How to prevent pilling
Even with the best yarn, a few habits make a big difference.
- Limit friction. Pills form where things rub: under the arms, at the cuffs, under a bag strap.
- Wash gently. Turn the piece inside out, use a laundry bag, a mild detergent and a wool or hand-wash program. Crocheted toys get extra wear; our guide on how to wash stuffed animals shows how to clean them without losing their shape.
- Block your project. Wet blocking evens out the stitches and gives a smoother surface.
- Remove pills carefully. Use a fabric shaver or sweater comb. Don't pull pills off by hand, because that drags more fiber out.
Pilling FAQ
Does acrylic yarn pill?
It can. Acrylic fibers are strong, so pills don't break off easily. Better-quality and "anti-pill" acrylics pill much less.
Does cotton yarn pill?
Very little, especially smooth or mercerized cotton.
Is there a yarn that never pills?
No yarn is completely pill-proof, but smooth, tightly spun yarns with long fibers come close.
Choose a yarn that fits your project
Cotton, linen or a well-spun wool: with the right yarn your work stays looking good for years. For things that get a lot of wear, pick a smooth, tightly plied yarn, and save the fluffy ones for pieces that don't rub.
