More sky-centered paintings on the go... I've become braver and switched to quarter-sheet paper now, and using my 2" and 1" flats for the majority of this stage. What I found out is that sable flats have so much more characteristics while doing the initial wet-in-wet washes -- they release water with a more even rate, and deposit pigments slowly, giving the painter more control when the paper is soaking wet. However, the synthetic flats tend to leave interesting color "streaks" when carrying a denser mixture of pigments, which can create some nice effects when painting water or texturize foreground areas.

I used mostly sable flats for the rainy clouds in the sky, but switched to synthetic flats and rounds for the foreground areas. I also tilted the paper to make color run down in diagonal directions to hint storm coming...
