The fan brush came in handy today. Loaded with paint, it makes a nice splat when jammed onto the page. Splashes are common with this technique. The plan was to glaze the surface with yellow pigment, so to make sure my ocher splats were preserved, I outlined them with my dip pen using sepia ink. I saved some of the white space with an array of latex-masked ornamentation. Before I removed the masking, I outlined the outer edge with blue ink, in case the yellow-to-white contrast was not enough.
I like the colors of this composition. The pattern only approximates uniform repetition, but the irregularity is not bothersome.
