Patterning again

How is it that an inanimate blank canvas can dictate what it does or does not want to be? There have been times that I have set out to create a piece and nothing I try works. So I leave it for a few weeks or months come back to it and viola! it goes together so smoothly. I haven't figured it out. My most recent piece is an example of that phenomenon.
