Design is so neat because so much of it happens in the background.
I opened a kinder surprise toy over Christmas, it was a paper balloon frog. Whose job was it to figure out how to fold that huge thing into a tiny kinder egg? I can just imagine them sitting at a desk with a pile of prototypes folding, folding, refolding.
Who designs the patterns on toilet paper? I bet that job is much more complicated than it seems - there are so many limitations. In my experience, simple and conservative patterns are the hardest to work with. They need to be unique enough so that the powers that be feel satisfied that they're new but they can't be too unique or too different or they're no longer conservative. There's very little wiggle room!
