I am no expert but I've been dabbling in bows for over 2 years (for personal use, not as a business). Some bows you will never get the way you want them, and some will come very easily to you. You'll develop your style, so to speak.
I know I will never ever be able to do big layered puffy bows as nicely as I'd like to. And I've come to terms with that so I focus on developing my style with other types of bows.
