Space Bar??? I was drawing along the shape. It worked reasonable well. I don't have much hand control. Magic wand and erasing have a tolorance.

Looks good as well as you can see. Like the ringer on a phone, sounds good, but it doesn't mean anything. There still may be pixels you don't see.

They can become a problem in other applications. I might draw an object for separation and get a clear backgoround and then fix any minor places.
