In the past, when I worked exclusively in acrylics, I would start by diving right into a blank canvas with what could only be described as a hurried frenzy of thick paint blending together on the canvas. I rushed through paintings, sometimes setting a timer.
My most popular pieces (judged by sales) were completed in 15 minutes.
Fast forward to my new interest in oils. Although I've been using oils less than a year, I am thoroughly and wholeheartedly a fan, eager to learn more and more. At first I hated oils, mostly due to my having not worked with them. The drying time was the most difficult thing to get used to.
