Whatever makes you happy, you put in your render.

Rendered for AB's Embroidery contest. Screenshot of inputs:

For the Bob Ross, I took a previous render, loaded it into GIMP, slapped a frame over it, and cut out the corners. Then I saved it and uploaded it back into Artbreeder. The wood was a stock image of some cutting boards that I found with Artbreeder's internal search feature. I cut out what I wanted and stretched it to fit the canvas as my background.
