But a fear of 'fiddling' shouldn't be confused with 'reworking'. Okay granted for the most part I'm quibbling about semantics. But if there's a clear difference in the process or even the thinking of the artist, then this can often be a successful and necessary part of the process.
On occassion when I take a painting to completion, I realize I still need it to sit for a while. Whether it be hours, days, weeks or months, this settling time for a painting can sometimes generate change and in most cases these carefully considered changes are for the better.
This is an example of a painting that had long periods of 'resting'. Though signed, I never felt it finished, while I continued to change colors in the table cloth, fruit and Lilies. I think it's fair to say I 'struggled' with resolving this painting, but when I finally found the right colors I new it was truly finished and was able to walk away happy, with the achievement.
