Uff-da, huh? It didn't help that I lost my coat closet (long story) and had 3 seasons of coats hanging on ONE over-the-door hook. But with an early start on the day Saturday morning and a lot of Pepsi, by the end of the day the room looked like this:
Look! A clean work space!
And another!
Before.... 
Ahhhh...
Big.Sigh.Of.Relief.
(Just don't ask me where I put all the stuff that was in there!)

PS - I would have felt even better about it if I'd gotten the pile of filing that is shown in the bottom right corner of pictures 1-3 put away. And maybe put up the window trim (finally) but, hey, I was out of Pepsi so I gotta take what I can get.
