I'm a bit on the fence with what Georgia is saying. I think that using everyday/common objects in artworks is not a new thing anymore, but it is still interesting, despite the fact that you say it's extremely common among art practices these days.
However, I also think that during the theory and practical side to our course we have been shown a lot of work using everyday or quotidian objects, such as our Art de Povera assignment. Maybe we've just been studying a lot of works like these lately which is making us a bit blind to the other artworks that are out there. Don't get me wrong though, I liked the art de povera assignment.
Anyway, I really enjoyed Nat and Gemma's speeches. I find Sze's work really interesting. I love it how both far away and up close show different characteristics of the work, the intricate detail of all the small parts put together to create something huge.
