There is no need to feel ashamed about not having artistic or design skills! Some people apologize when they admit they don’t design, as if it should be some kind of inherent talent. I would never try to create blueprints for a house, since I am not an architect! Years have been spent learning typography, code, aesthetics, color theory, balance, usability, and a host of software programs in order to create palatable media. Ever since the advent of desktop publishing, “everyone is a designer” – but the results are often an assault to the trained eye.
Sometimes it’s simply best to hire a professional.
