knowing When a Painting is Done

One of the hardest parts of painting for me has been to know when to stop. Today I am afraid I took it too far and ruined what I had. I was working on a very large scarf with dyes, which are pretty permanent and unforgiving.  I was not quite happy so I kept on painting and over painting with darker colors until I realized I was making it worse. Looking back I know that I should have left what was alone. I should have taken a break then came back to the project and looked at it with fresh eyes. Perhaps I can take this lesson in to life as well, knowing when to stop and when to let go. Today’s painting is an example of perhaps going too far or not knowing what I wanted in the first place
