So lately I have been trying my hand at adding mica to ink. So far it’s not quite as obvious as factory shimmering ink, or ink altered with commercial ink specific shimmer additives, but I was having a hard time finding any actual measurements. I was also going for tone on tone, as opposites to just siver and gold. I did put some gold in one, to see what shows up. I tried photographing my writing samples, but the lighting was pants and maybe the paper I was using didn’t show the shimmer as much as the cards do.
