So... When is a Collage finished???

So... When is your collage finished??? I think when you can look at it. finally smile, cross your arms and walk away! All day I kept walking back to add another piece, I just could not see the end in sight. Finally, after adding my third paper flower and ..... piece of lace, I felt that my piece was balanced and pleasing to the eye. My mother has always said that I was very "gaudy"....... I guess that is why I enjoyed putting this piece together so much!!! :)
