Knitwear bobbles because loose fibres rub together and tangle into small balls. You can slow it down by reducing friction, and you can fix existing bobbles with a fabric shaver or comb.
Why does knitwear bobble?
Short fibres work loose from the yarn. When the fabric rubs against a bag strap, your arms, a seatbelt or other clothes, those fibres tangle into little balls called pills. It is normal, and it does not mean the jumper is ruined.
Where does it happen most?
Under the arms, along the sides, on the cuffs and anywhere a bag rests. Soft, loosely spun yarns tend to bobble more than tight, smooth ones.
How can you prevent it?
- Wash less often and turn it inside out
- Use a delicate or hand wash
- Avoid rough zips and bag straps rubbing the same spot
- Do not tumble dry
- Fold it away instead of cramming it in a drawer
How do you remove bobbles?
Lay the jumper flat. Use a fabric shaver and glide it lightly over the surface. A fabric comb or a sweater stone also works. Go slowly and never pull a bobble off with your fingers, because that can tug the stitch.
Will bobbles come back?
Some will, especially in the first few wears, as loose fibres work their way out. Remove them early and they tend to settle down.
Is it worth fixing?
Absolutely. A knit that looks clean looks newer. That helps your cost per wear, which we explain in what a hoodie is really worth.
What else should you read?
Our guide to caring for knitwear covers washing and storage, and how to wash a knitted hoodie helps with the same fabric. Prevention is easier than repair, so build good habits early. Check your knits after each wear and remove the first few bobbles before they multiply. A little attention every few weeks keeps the surface smooth and the colours looking clean. It takes two minutes, and it makes an old jumper look much newer than you would expect. If a bobble will not budge, do not force it. Trim it with small, sharp scissors, lifting it slightly away from the fabric first. Patience pays off here, and a steady hand is better than a fast one.
