When I got my first Molotow pen. I remember everyone warning me that the ink pools into cracks and crevices. So I tried holding the work upside down. It’s truly a pain in the neck. But the ink can’t pool up. Only down to the high spots on the lettering.
I lean both wrists on the bench. I also lean a finger with the pen on the body to keep it steady. I then lightly dot the tops of the lettering slowly moving from letter to letter. In my experience. Stroking the letters or emblems with a Molotow pen is bad juju.
