Design is a slippery subject. Much of good design is a matter of taste, and tastes, like fashions, change. But leaving out the question of fashion in design, some tastes are better than others. You would expect someone who has studied design and has created what others consider good design to have better taste in design than the ordinary person. But some ordinary people have better design taste than others. How do they achieve this better design sense? By observation, simple observation. We are surrounded by examples of good design; all we have to do is take the time to look closely at what we take.
