Every season, there's somebody on Amazing Race who didn't learn how to drive a stick shift when they knew they were going to be on the show- or to swim. And somebody on Top Chef who doesn't know how to use a pressure cooker. It's the same with Project Runway- while they used to have stick figure models for most challenges, there was always a "regular woman" challenge.
I liked Wabi Sabi, which was really cohesive, but some of their materials still looked like something other than fabric, and I think the judges favored something where the origin were more disguised.
