My bedroom has been a shambles for a very long time... since I was a child really and into my teens and now my adult life as well. I often don't let my friends into my room as it is quite messy. Not dirty or dusty (I have a cleaner who does all that), but cluttery - lots of old paperwork around, clothes that I don't wear, the usual suspects.
So the task was to tidy, clean and organise the bedroom. It has taken a few sessions to do so, but I am now very happy with the result!
