When we talk about good design, we pay a lot of attention to function, shape, color, texture and proportion. And quite rightly: a well-designed space will take into account all these various elements, and the combination thereof. But what we don't talk about enough (in my opinion, anyway) is pattern. It seems that it's treated as an "extra" most of the time, something only for the brave, or only usable in certain situations. Isn't it time we changed that?
