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)
- Use a gentle or wool cycle with mild detergent, and dry flat rather than tumble drying
- Avoid rough fabrics rubbing against the knit (velcro, coarse bag straps)
- Let a sweater rest a day between wears so fibres recover — airing is often enough, so don't over-wash
How to remove pills
Lay the sweater flat and use a fabric comb or a dedicated sweater shaver, gliding gently in one direction. Avoid scissors or razors on delicate knits like cashmere — they can nick the yarn, and don't pull pills off by hand as 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: longer staple fibres and a tighter, denser knit hold together better, so premium wool and cashmere tend to pill less and settle sooner.

FAQ
Does pilling mean a sweater is low quality?
Not on its own — even fine natural fibres pill a little at first. Persistent heavy pilling after the break-in period points to shorter, lower-grade fibres.
Will my sweater stop pilling eventually?
Usually yes. Once the short surface fibres work loose and are removed, a good knit pills far less.
What's the best tool to remove pills?
An electric fabric shaver for sturdy knits, or a sweater comb/stone for delicate cashmere.
