Masking fluid is so much fun to create with. And lately I am loving the . Masking fluid is a latex liquid used to block out areas of a watercolor painting. Once it dries you can paint over it and retain the white paper anywhere you’ve applied the masking fluid. The pen makes it possible to draw, doodle or write really fine lines. When you are finished painting you simply rub it away and you are left with white space anywhere the masking fluid was applied.
