Well done on this! My stuff is about two suitcases' worth ever since moving abroad, it's amazing how much perspective you get when some things just have to be ruthlessly cut out to save on shipping fees!
I'm always trying to rationalise my wardrobe though, so I will try out the hanger flipping technique to see what I really wear. Great idea!
