Avoid using hot water or tumble drying, as this can cause shrinkage and damage the fabric. When storing your sweaters, it's important to fold them neatly rather than hanging them, as hanging them can cause stretching and misshaping. Keep them in a cool, dry place to avoid any damage from dampness or humidity. Additionally, if you notice any pilling on your sweater, you can remove it using a sweater shaver or pumice stone.
