I discovered most tailors and designers have the practical knowledge of sewing but lack the theoritical.
Today, in the fashion house I work, I sampled few workers with some questions.
For example, I asked, the small pocket at back of most trousers is called? Most said back pocket. Whereas the name is welt pocket.
Some don't even know the folding allowance given beneath a shirt or trouser is called Hem allowance
Anyways I'm saying this to make upcoming designers strive to learn sewing terminologies on your own, even if your masters/Ogas doesn't teach you.
It makes you look more professional and makes you charge high.
my though tho.
You can add your own terminologies, let's gist.
