For clothes such as sweaters and knitwear, if you use the iron directly to burn the tissue, the elasticity of the tissue will be destroyed. At this time, it is best to spray the water on the wrinkles with a steam iron. If the wrinkles are not very strong, you can hang them and spray them directly on the wrinkles. When they are dry, they will naturally level off. In addition, you can hang it in the bathroom and use the hot steam from the bath to make it smooth. Knitted garments are easily deformed and should not be pressed with heavy weight, just press gently.
