Short answer:<\/strong> Wool shrinks when it is exposed to heat, agitation or alkaline detergent – so wash it cool, by hand or on a wool cycle, with a pH-neutral wool detergent, and never put it in a tumble dryer. Squeeze the water out rather than wringing, dry it flat and away from radiators, and most knitwear will keep its size and shape for years.<\/p>\n

Why does wool shrink?<\/h2>\n

Short answer:<\/strong> Wool fibres are covered in tiny scales. Heat, moisture and movement make those scales lock into each other – the same process that makes felt – and once they lock, the fabric cannot go back. That is why a sweater that survives one hot wash is never quite the same size again.<\/p>\n

Can I machine wash wool?<\/h2>\n

Short answer:<\/strong> Only if the care label says so. If it does, use a wool or delicate cycle at 30 degrees or lower, with a wool detergent, a low spin speed, and the garment inside a mesh bag. If the label says hand wash, believe it.<\/p>\n\n\n\n\n\n\n\n\n

How do I dry a wool sweater?<\/h2>\n

Short answer:<\/strong> Lay it flat on a towel, reshape it to its original dimensions while it is still damp, and let it air dry away from direct heat. Hanging a wet sweater stretches the shoulders, and a radiator will felt the fibres.<\/p>\n

How often does knitwear actually need washing?<\/h2>\n

Short answer:<\/strong> Less often than most people think. Wool is naturally odour-resistant, so airing a sweater overnight between wears usually buys two or three more wears. Wash when it is visibly soiled, stretched out of shape, or genuinely smells – not on a schedule.<\/p>\n

How should I store knitwear for winter?<\/h2>\n

Short answer:<\/strong> Fold, never hang. Folded knitwear keeps its shape, while a hanger stretches the shoulders and the neckline over a season. Store folded pieces with a cedar block or a lavender sachet, and give them air before putting them away for the summer.<\/p>\n
