A love of Imperfection - Bedagade skönheter

When I see todays romantic love for decayed surfaces and spaces, I'm reminded of US artist Elana Herzog's art project Civilization and its Discontents, as seen in New York City 2003. 
In this textile project, Herzog stapled a series of Persian carpets in varying quality and condition, onto an art gallery's walls and then worked on them further to give them the right state of decay. Read more about her project here

What do you think? 
Where do you draw the line between imperfection and decay?
