Wear a cardigan multiple times?

Knit jackets are sensitive and therefore you should not wash them too often if possible. A few days you can wear them one after another. When washing, you should take care if it can no longer be avoided by dirt. A trick from me is to pull them to the left while washing, i.e. the inside to the outside. In the case of sensitive material, you should not wash more than 30 degrees and also use only a mild fine washing agent for wool gently so that the fiber is not attacked, so naturally as not to wash together with other garments that have zippers or the like and can damage the wool. After that, you should always let them dry in the air, which is most gentle, so it lasts longer and despite washing you have a cardigan in good condition that stays longer in shape.
