Libby Mills has an interesting discussion on her blog about where your work table faces. http://www.libzoid.net/blog/ She prefers facing the room. I do too. I like it that every time I lift my eyes, I gaze out over myworkspace through to the window and the view outside. It makes such a difference to my wellbeing and creativity. A lot of my work involves sanding and I can't tell you how much things have changed to the way I feel about sanding (luv it now!) since I've had this studio set up like this.
