I’ve found this video from Steve Mitchell’s The Mind of Watercolor so helpful in preventing overworked areas and understanding why they occur. I never took a formal watercolor course, so everything I learned comes from trial and error, instructional books/videos, and even a few kind souls who gently pointed things out to me about my technique. I still find myself returning to some of these same errors, especially “painting in the danger zone,” as Steve refers to it in the video. I highly recommend Steve’s videos. He has a ton of experience and I always end up laughing at his dry sense of humor.
