When I did set decoration, my mind was blown. Working on a film set is usually like being in the military (my first job out of school). Film work is often very regimented, but with set dec, there is no one telling you what needs to be done, and it is usually far ahead of schedule, so creative commons is given, and I never felt any pressure to rush. In fact, most of the time, we were so far ahead, that 80% of the time, there wasn't even a camera nearby.
