Mix together equal parts acrylic paint and dish soap with a soft brush—it's fine to just eyeball the proportions. This is scratch-off paint! The only catch is that it won't scratch off of just any surface. That's where the tape comes in.
What kind of paint do you use for scratch art?
Acrylic paint has good coverage, so it may only take a few swipes of the brush to completely coat the surface of the cardstock.
How do you make Scratchies?
Mix together two parts acrylic paint for every one part dish washing detergent. Mix slowly until well combined. Don't stir too vigorously or else you will get lots of air bubbles, and we don't want that.
