PLZ ANSWER QUICK. WILL GIVE BRAILNLY Question: Do you really need to know how to sew to be a designer?
I've heard stories of people who create successful lines of apparel with just a great idea. At the very, very least, to be a success as a fashion designer, one needs to know how clothes are constructed and sewn. One doesn't necessarily have to experience it firsthand, but it most certainly helps. Without technical experience, a designer is solely reliant upon in-house sample hands or a production factory abroad to implement the concepts. When one has firsthand experience, then one can say to the sample hand or factory, "What do you mean you don't know how to do X? Let me show you."

According to the passage above why is it important to learn how to sew if you want to be a fashion designer?
