Why did that Old Penny turn Green?
Have you every picked up an old penny off of the street that was green? The older ones will "rust" green, at any rate, those made before 1982. The later ones are mostly zinc. This is a patina, the same one that gives the Statue of Liberty and every other bronze it's color.
Letting Go
It's always hard to let go of a piece of art and call it finished. That wonderful terrible time when you have reached the goal, but still aren't quite there.
