It is important to know how to hang sweaters since an improperly hang sweater can permanently get stretched out of shape. In general, using a plastic or wire hanger typically causes strange bulges in the sweater’s shoulders. It is better to use a padded or wide wooden hanger if you want to hang up a sweater.
The secret to hanging your sweater without stretching it is folding it before you hang it up. Fold it vertically in half before you put the hanger hook in the armpit area and draping the waist and folded sleeves over the hanger. It is important for helping distribute the weight as well as reducing stretching.
