Keeping Knitwear in Good Shape

Why knitwear needs its own rules

Knitted fabric is a structure of loops, not a solid weave, so it stretches, snags and holds shape differently from a shirt. Treat it like a woven garment and it sags at the shoulders, bags at the elbows and pills where it rubs. Treat it as the soft, springy thing it is, and it keeps its form.

The good news is that the care is undemanding. It mostly asks you to slow down at the moments where damage happens: washing, drying and putting away.

Fold, never hang

The single most useful habit is to fold knitwear rather than hang it. A hanger lets gravity pull the whole weight of the garment down through the shoulders, which stretches the yarn and leaves those two sad points where the hanger sat.

• Fold jumpers in half and lay them flat on a shelf or in a drawer.
• Stack heavier knits at the bottom so they do not crush lighter ones.
• If space is tight, fold in three so the shoulders never bear the load.

A hung jumper slowly grows a size it never asked to be. A folded one keeps the shape it left the shop with.

Wash gently and less often

Knitwear rarely needs washing as frequently as you might think. Wool in particular resists odour and freshens with a simple airing, so a night on a clothes airer often does the work of a wash without the wear.

When it does need cleaning, be gentle. Use cool water and a mild detergent made for delicates or wool. Turn the garment inside out, and either hand wash or use a wool cycle that keeps the drum slow and the spin low. Heat and agitation are what shrink and felt wool, so both are the enemy here.

Dry it flat

How you dry knitwear matters as much as how you wash it. Never wring a wet jumper; twisting forces the loops out of true and can leave a permanent kink. Instead, press the water out gently.

• Lay the wet garment on a clean towel.
• Roll the towel with the jumper inside and press to blot the moisture.
• Unroll, then reshape the jumper flat on a fresh dry towel, easing it back to its proper width and length.

Leave it flat, away from direct heat and strong sun, until fully dry. A radiator or a hot windowsill dries the yarn hard and can scorch the fibres.

Deal with pilling and snags calmly

Those little bobbles, called pills, form where the fabric rubs against itself or a bag strap. They are normal, not a sign of poor quality, and they are easy to remove. A fabric comb or a dedicated de-pilling tool lifts them away and instantly makes a jumper look fresh again. Work in one direction on a flat surface and go lightly.

Snags need a different touch. Do not cut a pulled loop, or you risk a hole and a run. Instead, use a blunt needle to coax the loose thread through to the inside of the garment, then gently stretch the fabric around it to redistribute the yarn.

Store it properly

Knitwear put away for a stretch of time needs a little thought. Make sure it is clean before it goes into storage, since even invisible traces of food or skin can attract moths and set into stains over time. Fold it into a breathable box or a cotton bag rather than sealed plastic, which can trap damp and leave a musty smell.

A cedar block or a few dried herbs in the drawer help discourage moths without the harsh scent of mothballs. Give stored knits an occasional shake and airing so nothing sits pressed and forgotten for too long.

The habits worth keeping

None of this is complicated, and you do not need special equipment. The whole of knitwear care comes down to a handful of gentle choices repeated often: fold instead of hang, air instead of over-wash, blot and lay flat instead of wring and hang, and lift pills before they spread.

Do these small things and an ordinary jumper stays soft, keeps its shape and looks looked-after long past the point where a neglected one would have gone shapeless. The habits take only moments each, and they slot easily into how you already wash and put things away, so there is no real chore to dread. Good knitwear is quietly generous; it just asks to be handled kindly, and it gives back years of comfort in return for that small consideration.
