I'm playing in my journal and trying to see if there was a simple way to paint a night sky with watercolours.
Here is the result of sprinkling kosher salt over it:
It didn't really work at all and just left traces of salt all over the surface.
This is the result of dipping an old toothbrush into melted wax and running a toothpick across it to spray the page with droplets:
A lot better but not quite there. The wax leaves a residue on the paper, though I'm not sure if it matters yet.
Any other ideas?
