I started this painting a few days ago, and ended wiping it off. I was trying too hard for too much detail on the sliced orange. I set it aside and tried again today. I like this version better.
After I wipe off a painting, there is still a faint image of the prior efforts. Jennifer Bellinger once described it as a "ghost painting". You can use that faint image as an underpainting. It made the second attempt easier.
