Watercolor is a wonderful medium. Most watercolorists feel a sense of satisfaction when they "savor the whites", i.e. preserve white areas of the paper that sparkle. Wow....that is so much easier said than done! I gave up using masking fluid (a.k.a. liquid frisket) years ago as the process was messy, awkward and left behind the most awkward shapes. It was done with a paint brush coated with soap which ended up ruined. This year I rediscovered masque....in the form of the Masquepen, which has a needle-like dispenser, making the process more agreeable. The dots on "Dancing Shoes" were formed with this magical substance that is fed onto the paper like glue, left to dry, then subsequently peeled off. Even though I am not a great fan of masking fluid, I have changed my attitude about it....we artists need all the help we can get!
