Pilling Prevention and Repair
Pilling — the small fuzz balls that form on the surface of wool garments — is partly inevitable but largely manageable. Good fibre choice and gentle care minimise pilling; a sweater stone or fabric shaver removes existing pills.

What causes pilling
Pilling happens when short fibres on the surface of the yarn break loose and tangle into balls. Short-staple wools (merino, especially) pill more than long-staple wools (BFL, Wensleydale). Single-ply yarns pill more than 2-ply or 3-ply yarns.
Prevention
Choose long-staple, multi-ply wools for high-friction garments (sleeve cuffs, sweater armpits, cardigan fronts). Hand-wash gently. Avoid friction-causing accessories (rough scarves, abrasive bag straps).

Removing pills
A sweater stone (a soft pumice for sweaters) gently removes pills with a wiping motion. A battery-powered fabric shaver works for larger areas. Manual removal — picking off pills with fingers — works for small areas but is slow.
Frequency
De-pill after every wash. The longer pills stay on the surface, the more they grow as more short fibres tangle in.

- Choose long-staple multi-ply wools for high-friction garments.
- Use a sweater stone or fabric shaver for de-pilling — never scissors or razors.
- De-pill after every wash for the cleanest finish.
In depth
Pilling is a normal characteristic of wool fabrics, not a sign of poor quality. Even the finest wool sweaters pill in their first year as the short fibres on the yarn surface work loose. Regular de-pilling keeps the fabric looking new; with care, a wool sweater can be worn weekly for a decade with no visible decline.
