A drop!? A drop?!
I could probably paint a couple of paintings... big paintings... with all the paint I've spilled. There are two major and rather recent disasters that I can think of.
I often have my paintings hung close together. In my old studio, the painting I would be working on would hang in the space surrounded by all the paint on the wall... maybe 9" away from a finished painting on either side. There was one incident in which I had a large cup of water for cleaning the acrylic off my brushes sitting on the top of my workbench. Somehow I swung around and knocked the cup over splashing water over the bottom third of a completed painting. Of course, it ruined the surface of the pastel and stained flat areas of acrylic. I had to rapidly dry the surface with a blow dryer and then repaint the acrylic (not too hard) and then redo the pastel from the reddish primer which took at least a week. It was a learning experience, to say the least. From then on I kept my water cup on the floor... down low where damage from any accident would be minimal.
But then there was a worse accident which happened a little over a year ago. I was taking a weekend drawing/painting class to earn continuing education hours required by my job teaching art. I would often roll up paintings and take them into the school to discuss/critique them. My latest painting, at the time, was nearly done with the exception of the figure and the decorative elements in the arch and halo.
When I got home, I left the painting in the trunk because it was pouring. It kept raining over the whole weekend so I decided to let it stay in the trunk where it would be safe. Sometime during the week, my brother threw a heavy car jack into the trunk on top of the rolled-up painting.
When I unrolled it, it had major creases and cracks across the entire painting in several places. I tried any number of methods to fix it. I sprayed the back with water and blow-dried it; I ironed it; I painted over the cracks with multiple layers of paint. There was no saving it. Eventually, I got a large sheet of tracing paper and copied the image. I also measured all the decorative elements and their placement. I transferred the image to a new paper and then redid the entire painting. What was amazing was how rapid the process was with the second painting. It made me recognize how much time in the painting process is spent in thought. It also made me realize how much more difficult it is to create an original painting than it is to make a copy. The final painting actually ended up as one of my best IMO... almost impossible to tell from the "original".
