Alcohol Ink Class

What is Alcohol Ink? Artist Janet Folkman describes it like this:
Sharpies are alcohol based markers . if you scribble on a non porous surface, then add a slight amount of rubbing alcohol, the inks begin to bloom (or liquify) and move around. She uses many tools to “paint” with the inks. Call 518-753-4230 to register for this class. Fee: $30
