Here we have a 7″ square watercolor painting of a yellow pear on a red-checkered tablecloth painted using the Liquid Frisket and Masking Tape techniques.
This tutorial uses a representational approach the the subject matter, pre-planning was needed to protect areas needed for later stages of the painting. More spontaneous approaches to masking are also viable alternatives.
You can use liquid frisket on areas already painted for some amazing multi-layered effects. This works with varying degrees of success depending on the underlying pigments.
