Caring for Knitwear So It Keeps Its Shape

Knits are built to move, and to be minded

A knit is a cloth built from loops of yarn, and those loops are what give a knit its stretch and its soft, following drape. But the same loops that let a knit move also let it stretch out of shape if it is handled wrong, because a loop pulled and left pulled does not always spring back. So knitwear lives or dies on care. Treated well, a good knit holds its shape for years. Treated carelessly, it sags, bags, and pills within a season. The care is simple once you know it.

Why knits lose their shape

Understanding what goes wrong tells you how to prevent it. A knit loses its shape mainly through weight and heat: the weight of water or of hanging pulls the loops long, and heat can shrink or felt the fibre. Both are avoidable.

• Hanging a wet or heavy knit lets gravity drag the loops down
• Wringing twists and distorts the loops out of true
• Heat in washing or drying can shrink and felt the fibre
• Rough handling rubs the surface and raises pills

Every one of these is a way of forcing the loops out of their natural shape or damaging the fibre. Avoid them and a knit largely keeps itself, because the loops want to return to their resting shape if you let them.

Washing without stretching

The safest way to wash a knit is by hand in cool water, gently, without twisting or wringing. Fill a basin with cool water, add a little gentle soap, and let the knit soak and move without agitation. Press the water through it rather than rubbing.

Never wring a knit. Wringing twists the loops and forces them out of shape, and a wrung knit often never fully recovers. To remove water, press it out gently or roll the knit in a towel.

When you lift a wet knit, support its whole weight rather than letting it hang from your hand, because a wet knit is heavy and that weight will pull it long in seconds. If you must machine wash, use the gentlest cool setting and a bag, but hand washing is far kinder and not much slower.

Drying flat

Drying is where most knits are saved or ruined, and the rule is simple: dry a knit flat, never hung. A wet knit hung to dry will stretch long under the weight of its own water, arriving misshapen with a sagging hem and dropped shoulders.

Instead, lay the knit flat on a towel and let it dry there. Before you leave it, ease it into shape with your hands: square the shoulders, straighten the body, bring the hem level, so it dries in the shape you want it to keep. A knit dries in whatever shape you leave it. Turn it over partway through so both sides dry, and keep it away from direct heat, which can shrink or felt it. Dried flat and shaped, a knit holds its form; hung wet, it loses it.

Folding, not hanging

Storage matters as much as washing, and knits should be folded, not hung. A knit hung on a hanger stretches under its own weight over time, developing hanger horns at the shoulders and a dropped length, because the loops slowly give under the constant pull.

So fold your knits and store them flat on a shelf or in a drawer. Fold them neatly along their natural lines so the folds do not distort the shape. If you are short of shelf space and must hang a knit, fold it over the bar of the hanger rather than putting it on the hanger by the shoulders, so the weight is shared across a fold rather than hung from two points. But flat folding is best, and it keeps a knit in the shape you dried it into, ready to drape properly when you put it on.

Dealing with pills

Over time even a good knit raises little pills where the surface rubs, at the cuffs, under the arms, wherever there is friction. Pills are not a sign of a bad knit, but left alone they make it look tired, and removing them is easy.

Gently lift and remove the pills rather than pulling them, which can drag the loops. A knit comb or a fine, careful blade drawn lightly across the surface lifts the pills away and restores the smooth face of the cloth. Work over the surface without stretching it, only where the pills are. A knit de-pilled now and then looks cared for and fresh, because pilling is only the loose surface fibres, not the structure of the knit itself.

The rhythm of good care

Put together, caring for knitwear is a simple rhythm you fall into once you know it: wash gently by hand in cool water, never wring, press the water out, dry flat and shaped, fold to store, and de-pill now and then. None of it is hard, and it takes only a little more time than careless treatment, but the difference over years is enormous.

A well-cared-for knit keeps its shape, its drape, and its soft surface for a very long time, falling from the shoulder the way it did when it was new. A carelessly treated one sags at the shoulders, bags at the hem, and pills all over within a season. The loops that make a knit lovely are also what make it vulnerable, so a little minding is repaid every time you put it on and it still falls right.
