I'm taking an Organizing Your Art Biz online course from Alyson Stanfield, a really good teacher who is on top of all this kind of thing. I struggle, and I have to recommit myself and restart the systems at least once a year. My favorite part, believe it or not, is the good-old physical clean-up. My "before" picture really isn't bad, but my after picture makes me really happy!
And the big basket is empty.
