Last year I went to an outdoor art fair and met a woman (so sorry, I can't remember her name) who, because of a neurological affliction, could not hold a paintbrush steady. She had been an accomplished painter and then was struck with a palsy. Her solution was to paint using only her fingers. I was completely amazed at the detail she was able to achieve. I went away thinking this was an amazing feat.
Then yesterday I was trolling YouTube for artist demos, as I'm wont to do, and came across the Russian Painter Igor Sakharov. I watched him paint nearly an entire floral painting using only his fingers. Eureka! I decided to try it.
I've been frustrated at how stiff my florals look when I try too hard. This method had me exclaiming, "I love this!" several times. The tactile nature of this method really appeals to me and I love how soft the result is. I'm definitely going to fool around with this some more.
I found that small details needed brushes, at least at my ability level.
Here's the painting so far. I made a little slide show.
