My surgery took six hours. The narcotics kept me comfortable, and the hallucinations were entertaining. At one point I imagined the pillows under my arms were jewel-encrusted, and that they were also paintings that I was working on. And they were coming out so well. (Yes, that was the drugs talking.)

In 2018, I developed bilateral trigger thumbs, which meant I could not tie my shoes, write my name, or hold a brush, much less paint. I wanted to keep painting while contemplating the possibility of surgery, but with both hands in metal braces, I had to devise a new way to work.

Kyoto is an ancient city in Japan that is home to several important Buddhist monasteries. On a rainy day ,I was walking through the grounds on one such monastery. Cherry blossoms had fallen on the sidewalk and were held in place by the moisture of the rain. I photographed the pattern it created. Then years later as I worked on this painting it reminded me of that moment, and, in fact, of that whole extraordinary day.
