After wetting, local heating at high temperature. It is more troublesome to operate. If the whole sweater is loose, it can be completely soaked and steamed in a pot for about 20 minutes, and then it will be ground and dried. The shrinkage effect is very good.

Method of use iron

Open a large cardboard box and cut the cardboard into human size according to the reasonable size of the sweater. After the sweater is washed and dehydrated, put the cardboard into the sweater to spread it left and right, and shorten the length, then iron it with an iron and spread it out to dry.

If your sweater is pure wool, you can soak it in warm water of 30-50 degrees, let it recover its shape slowly, and then put it in cold water to set it. Finally, remember not to wring it out when drying, but to dry it flat. If your sweater is not too expensive, there is really no way to restore it.

In addition, you can also go to the dry cleaner and ask if you can recover.
