(for a tumblr ask)
i like doodling with the sai binary tool a lot (AS ONE CAN SEE since i doodle with it a lot),it feels somehow different from regular pens? like, not only does it look different but the way it moves when i draw makes it very pleasant for quick doodles
also i like to sometimes have that drastic change, since i usually draw with very soft brushes and the binary is AS HARD AS CAN BE.
