Must I iron each sweater separately?

Each sweater should be ironed separately. Generally, sweaters need to be ironed to restore their original style, which is convenient for wearing or keeping. Sweaters need ironing or shaping before ironing. Sweaters should be ironed with a steam iron at 135 ~ 145℃.

Ironing: there is a saying in the industry: three points make seven points iron! This shows the importance of ironing and shaping. A good sweater will make a separate ironing board for each model in the ironing process, while a low-grade sweater is prone to deformation because of its hasty cost saving.
