Caring for Handknitted Garments Through the Seasons

Start With the Fibre, Not the Label

Every handknitted garment you own is a small piece of engineering. Wool fibres are covered in tiny overlapping scales, and those scales are what give wool its extraordinary bounce, warmth and resilience — but they are also what make it vulnerable. Add heat, moisture and friction and those scales lock together: that is felting, and it is irreversible. Understanding this one fact will shape almost every decision you make about caring for your knits.

Woollen yarns spun from untreated fleece are the most forgiving in wear and the most demanding in the wash. Superwash yarns have been treated to smooth or remove those scales, so they tolerate a cool machine cycle, but they still stretch under their own weight when wet. Alpaca drapes beautifully and grows with wear. Cashmere is soft but pills if abraded. Cotton and linen blends hold their shape through warmer weather but relax when wet and dry slowly. Read the ball band, and if you have lost it, treat the garment as though it were pure untreated wool. That approach never does harm.

Air Woollens Between Wears

The single most effective thing you can do for a knitted garment is to wash it less. Wool is naturally odour-resistant, and most of what a jumper picks up in a day is moisture and body heat rather than dirt. Twenty minutes on a line in the shade, or folded over a chair by an open window, will refresh it wonderfully.

• Give each garment a full day of rest between wears so the fibres can spring back into shape.
• Air outdoors in shade on dry, breezy days — direct sun fades dye and can make fibres brittle over time.
• Never drape damp knits over a radiator or airing cupboard shelf; gentle warmth from below can shrink and stiffen them.
• Fold jumpers and cardigans for storage. Hanging on a hanger, wire or padded, pulls the shoulders out of shape.
• Rotate your favourites rather than wearing one piece three days running.

Hand Washing: Cool Water, Gentle Handling

When a wash is genuinely needed, do it by hand. Fill a basin with cool water — lukewarm at most, and never above 30°C — and dissolve a pH-neutral wool wash or a gentle, non-biological detergent completely before the garment goes in. Fabric softener, bleach and enzyme-heavy biological powders all attack protein fibres. So does rough handling.

• Submerge the garment and let it soak for ten to fifteen minutes, pressing it down gently with flat hands.
• Do not rub, scrub or agitate. Dirt lifts out of wool on its own; friction is what felts it.
• Squeeze the water out gently — never wring or twist.
• Rinse in water of exactly the same temperature. A sudden change from warm to cold is a common cause of accidental felting.
• Lift the garment with both hands supporting the weight, then roll it in a clean towel and press to remove excess water.

Dry Flat, in the Shade, Shaped to Size

Wet wool is heavy and completely lacking in support, so hanging a washed jumper on a line will stretch it beyond recovery. Lay it flat on a mesh drying rack or a clean towel instead, and take a moment to reshape it to its original measurements. Pat the edges straight, ease ribbing back into line, and spread sleeves out rather than letting them crease.

Dry in the shade, away from direct sun, radiators and tumble dryers. Airing cupboard warmth is gentler than a radiator but still best avoided for damp knits. Most garments need twenty-four to forty-eight hours to dry thoroughly, and turning them once halfway through helps. If a piece still feels slightly damp at the seams, leave it — damp wool packed away will smell musty and can grow mould.

Store It Well When the Season Turns

Always store knitwear clean. Moths are drawn to perspiration, food traces and skin oils far more than to wool itself, so a garment worn all winter and tucked away unwashed is an open invitation. Fold rather than hang, and choose breathable cotton bags, cotton pillowcases or well-sealed storage boxes rather than vacuum bags, which crush fibres and trap any residual moisture.

• Cedar blocks and dried lavender help deter moths but need refreshing every few months; neither is a substitute for cleanliness.
• Check stored knits at the start and end of each season, shaking them out and looking along seams and underarms for tiny holes.
• Store fine lace shawls flat between sheets of acid-free tissue, lightly folded rather than sharply creased.
• If you suspect moths, seal the item in a bag and freeze it for a fortnight, then let it come to room temperature before storing again.

Small Rituals That Keep Knits Going for Years

Pilling is not a sign of poor quality — it is simply short fibres working their way loose. Remove bobbles with a gentle sweater comb, a soft brush or, very carefully, a clean razor, working on a flat surface and holding the fabric taut. Never pull at a pill; you will drag more fibre with it.

Snip loose ends rather than tugging them, and catch small holes early with a woven darn or a few stitches of duplicate stitch in a matching yarn. Rest after each wear, wash rarely and gently, dry flat and in shade, store clean — do these things and a well-made jumper will outlast most of the shop-bought things in your wardrobe. That is the quiet pleasure of making and keeping wool: with a little patience, it simply gets better with the years.
