I usually paint on a block of watercolor paper, on which all four sides are tacked down to prevent warping. Today, I used a single sheet of light weight paper that I taped to a board to accomplish the same end: preventing the paper from buckling.
I was surprised that the pigments I used did not soak into the paper as they do with the cold pressed paper I normally use.
I applied texture by using stabby brush strokes and blotting the wet paint with paper towels. I used a sponge to lighten certain areas and applied more pigment to increase contrast with some of the shapes that coalesced on the paper.
