Classic cosy cardigan. Made from the softest lambswool.
Lambswool can look after itself. It’s spent a good few evolutionary cycles learning how. This means your sweater will resist stains, wrinkles and odours. From time to time it may need to take a breather for an hour or so. Hang it up outside. Or lay it down flat on your bed. From time to time you may decide to give it a wash. A gentle wool cycle will do, although hand wash is best.
