Today I discovered that oil pastels can be used as a resist for watercolors. This opens up a lot of possibilities because I am really bad with pastels, I feel like they just make smudgy impressions that get grayer as you work. I was excited to use my new technique to copy this blurry photo of the Jefferson Monument that I love:
Oh. It's not masking fluid. Once the pastel resist goes down that part will never be water colored. I put this pastel down very loosely, obviously, because I couldn't see it (white on white) and I usually put my fake masking fluid (rubber cement) down generally where I want it.
