I drew narrow traces of masking fluid with a wide-gage hollow applicator. The gage wasn’t narrow enough to allow a smooth outflow. The fluid bunched up and formed a bead at regular intervals across the page. Once I shook the paper at 90 degrees to the direction of the parallel lines, the beads turned into lines oriented at 90 degrees to the other lines.
After the frisket dried, I had some fun spreading different colors around. I used Prussian and ultramarine blues and cadmium red light.
After I peeled off the masking material, I found that my image had been captured by a net.
