I taught a painted paper class of techniques from my book and I gave all my students a customized paint brush. I have always collected red paint brushes, then I decided to create my own cool red brushes... I purchased a case of chip paint brushes, wrapped painters tape around the metal and spray painted them red. Then I use rubber stamps to add a word or a quote and tie a piece of twine to the bottom. I use these inexpensive paint brushes when I make my painted paper and canvas, I like the texture it creates on the surface of the substrate.
