Many people who paint with oils and acrylics — which are easy to correct — find watercolor intimidating. Watercolor’s virtues are portability, ease of setup, lack of fumes or toxicity, and the translucence of the white paper shining through. The magic (and frustration) of watercolor is that when two wet areas touch, the paint flows between them. Wet paint is attracted to other wet areas, but it won’t go into dry areas. Here, after painting the top half, I “painted” the bottom half with clean water and let the paint do its thing.
