I have had a couple of fun but frustrating days painting fabric for a new quilt. I need blue-violet for a specific project, and Setacolor "ultramarine" is a great starting point since it is a deep blue with just a hint of warmth -- when used full-strength, that is. I need lights, but it becomes cooler and closer toward true blue when it is diluted. I haven't found the right mix of violet and ultramarine to make a cool lavender. Ha ha, I am forced to play until I get it right!
I started with dampened Kona white PFD. I dunked it in a dilute bath of ultramarine and spread it on my work surface. While it was still wet, I drew diagonal lines of violet straight from the bottle (mixed 1:1 with water). Some of the lines are still visible, but there was a lot of color migration, too. Once it was dry, I stenciled through sequin waste with a mixture of Lumiere blue pearl and Neopaque violet, then added texture with the same mixture on a sea sponge. Even though it is a bit cool and blue to be my target color, it will make a fun background in my project.
