Many watercolor artists use liquid frisket to mask off areas of their paintings that they want to preserve for later attention. But I like to alternate applications of frisket with transparent glazes to create unusual and varied textures. I usually repeat this process two or three times, starting with transparent, staining color washes first and allowing each step to dry thoroughly in between each layer.
The secret of my success, though, is applying frisket by unusual means. I have several methods for putting frisket on my surface, including drybrushing, spattering with a toothbrush or big brush, sponging with natural or synthetic sponges, and dabbing with crumpled paper. Be creativeyou may find a few combinations or completely new application methods of your own.
