In art school I learned how to use oil paints, but almost passed out one night when I was cleaning my brushes and palette with turpentine. The toxticity of the turp was so strong I almost fainted. It was heartbreaking because I loved the medium, and thought it the most expressive way to paint. So… I forced myself to change to watercolor instead of frying brain cells with the toxic cleaners and mediums that you add to oil. So I painted in watercolor for a long time.
Then the paintings started selling and I had to paint more. Then I had to frame them. The cost was staggering. You have to mat it, you have to mount it, you have to frame them. Oils? You can buy gallery wrapped canvas, paint around the corners and hang it on the wall. I liked that, especially when you consider that oils also sell for almost double what a framed watercolor sells for.
Then a miracle happened! I discovered water based oils, I was in heaven. No more turpentine, no more dead brain cells in the name of art, no more avoiding the medium I liked best. So, today I paint with water based oils, and love it. That’s my medium of choice these days.
