How to Get Rid of Bobbles on Jumpers (and Stop Them Coming Back)

The short answer

Lay the jumper flat on a table, smooth it out, and run a fabric shaver or knit comb lightly over the bobbled areas in one direction, without pressing. Work in small sections and stop once the surface is smooth. To prevent bobbles, wash knits inside out on a cool wool cycle, skip the tumble dryer and rest them between wears.

“Bobbles are what make a good jumper look tired years before it is. Ten minutes with a de-bobbler on a Sunday evening does more for your winter wardrobe than buying another knit.”Her take

Why do jumpers bobble?

Bobbles, or pills, form when short loose fibres work their way out of the yarn and tangle into small balls on the surface. Friction is the main cause, which is why they gather under the arms, on the sides where your arms brush, at the cuffs, and wherever a bag strap or seatbelt rubs.

Softer, looser and blended yarns pill most. Very soft wool, cashmere, acrylic and wool-acrylic blends all bobble, especially in the first few weeks of wear. Tightly spun, smooth yarns pill less. Bobbling isn't always a sign of poor quality; even good knits pill at first as the loosest fibres work out.

Step by step: how to de-bobble a jumper

Work on a clean, flat, hard surface in good light, never with the jumper on your body.

Lay the jumper flat and smooth out any creases, so there are no folds for the blade or comb to catch.
Start with the worst area, usually the underarm and side seams. Hold the fabric taut with one hand.
Glide the shaver or comb lightly in one direction, letting it skim the surface. Don't press down or go over the same spot again and again.
Empty the shaver's lint chamber often; a full one stops cutting cleanly.
Turn the jumper over and repeat on the back and sleeves, then give it a gentle shake.

Fabric shaver, comb, razor or tape: which is best?

A battery or rechargeable fabric shaver is the quickest and most even for most knits, including chunky and medium-gauge wool. Look for one with an adjustable height guard, so it doesn't catch thick stitches. A fine-toothed knit comb or a fabric stone is gentler and better for delicate cashmere and fine merino, but it's slower.

A disposable razor works in a pinch on fine, flat knits: hold the fabric taut and pass the blade lightly downwards. It's easy to cut a hole, so avoid it on chunky or loose knits. Sticky tape or a lint roller lifts loose fluff and a few bobbles, but it won't remove established pills. Never pull bobbles off with your fingers; that drags more fibres out and makes the next lot worse.

How to wash jumpers so they bobble less

Turn knits inside out before washing, so the outside surface rubs less against the drum and other clothes. Use the wool or hand-wash cycle at 30°C or below with a wool detergent, and wash them with other soft items rather than jeans, towels or anything with zips. A mesh laundry bag adds extra protection.

Skip the tumble dryer. Squeeze out water without wringing, roll the jumper in a towel to absorb more, then dry it flat away from radiators. Washing less often helps too: airing a jumper overnight between wears is usually enough unless it's actually dirty.

How to wear jumpers so they last

Rest knits for a day or two between wears so the fibres recover. Notice where your bag sits: a crossbody strap across the front of a soft jumper creates bobbles in a diagonal line. Switch to carrying the bag by hand or on the other shoulder for your best knits.

Store jumpers folded, not hung, so the shoulders don't stretch, and keep them in a drawer or breathable bag. Do a quick de-bobble every few weeks rather than waiting for the whole jumper to look worn; small, light passes take fewer fibres off than one heavy session.

When is a jumper too far gone?

If de-bobbling leaves the fabric visibly thin, see-through or shiny, it's time to stop. Every pass removes a little fibre, so a jumper that pills heavily every week will eventually wear through. Hold the de-bobbled area up to the light: if you can see clearly through it where you can't elsewhere, leave it.

Heavily pilled jumpers can still be worn under a coat, as a layer for walks or around the house. Keep your best-looking knits for when they'll be seen.

Questions people ask

Is it bad to de-bobble a jumper?

Not if you do it lightly. Each pass removes some fibre, so skim the surface gently and avoid pressing or going over the same spot repeatedly.

Do cashmere jumpers bobble?

Yes, often in the first weeks of wear. Use a fine knit comb rather than a shaver, and wash them inside out on a cool wool cycle.

Can I use a razor to remove bobbles?

On fine, flat knits, carefully, holding the fabric taut and moving the blade lightly in one direction. Don't use one on chunky or loose knits.

Why does my new jumper bobble so quickly?

Soft and blended yarns release loose fibres early on. The first rounds of bobbles are normal; they often reduce once the loosest fibres are gone.

Does fabric conditioner stop bobbling?

Not reliably. Turning knits inside out, using a cool wool cycle, avoiding the dryer and reducing friction from bags help more.

The takeaway

Flat surface, light passes in one direction, inside-out cool washes, no tumble dryer, and keep crossbody straps off your softest knits.
