Well, we are only midway through a complete basement makeover, but I'm liking it pretty well right at the moment. I've 'scored' the small room on the southeast of the basement, which gets me daylight - actual sunshine sometimes - and also allows me to keep my clutter all to myself.
Here's a before picture, of my dark northeast corner of the basement. This is often how I work: I drop half finished works from the tall stool to the floor, so I can get a look from a bit further away. Then I sit on the floor and pull out my bin of rejected paintings. My paintings often morph into collages as I throw the colors and patterns around and they overlap, accidentally or on purpose. Obviously I was having either a wonderful or an awful day here. Probably a wonderful one!
And, here's the current AFTER picture. Obviously not too much work getting done here yet, but just wait, it'll look like BEFORE pretty soon.
