I have been using Fluid paper for a few years now and find that it's a great value for the price. The quality is suitable for beginner to intermediate level painters. Very easy to work with, accepts watercolor paints, pencils, aqua crayons and markers well.
I'm not a stencil artist but a silversmith. I have several of the 1" brushes, and they are perfect for sweeping my bench. I use the brushes to sweep the silver and gold filings off my bench, and they do a superb job of cleaning loose metal bits off my projects. I don't like to use any other brushes. I use the smaller ones ( the 1/2" and 3/8") for gently cleaning wax models and jewelry in progress. These brushes have greater control, stiffness and yet pliable bristles that does the job very well. I'm sticking with these brushes for a very long time.
