Those little balls of fibre — "pills" — form where a knit rubs against itself or your bag, belt or coat. They're normal on natural fibres, and easy to prevent and fix.
Why sweaters pill
Friction lifts and tangles short fibres on the surface. New sweaters often pill a little at first as loose fibres work out, then settle down. High-friction spots — underarms, cuffs, where a bag strap sits — pill most.
How to prevent pilling
- Wash gently and inside out — less friction (see our care guide)
- Avoid rough fabrics rubbing against the knit (velcro, coarse bag straps)
- Let a sweater rest a day between wears so fibres recover
- Don't over-wash — airing is often enough
How to remove pills
Lay the sweater flat. Use a fabric comb or a dedicated sweater shaver, gliding gently in one direction. Don't pull pills off by hand — that can snag the knit. A few minutes restores a smooth, like-new surface.
Does pilling mean low quality?
Not necessarily — even fine cashmere pills slightly at first. Persistent heavy pilling can signal shorter fibres, though; our guide on judging cashmere quality helps you choose well next time.
