Why you may ask? I can’t tell you how many times I have watched a sweater be put on a hanger and the weight of the material stretches the sweater until it’s deformed!
Another thing I have seen happen is that people use a thin hanger and when they go to wear the piece it has little bump in the shoulder which is very hard to get rid of.
Solution. Fold your sweater and knits to keep them in the best shape.
Has this ever happened to you?
