One thing a painter should do to make his work look better? in Tips & Advice: Painting Posted April 8, 2011 Personally, my workhorse brush is the WN7 00, followed by the 1 and the 0 respectively. I almost never use the 000. My 00 does about 75% of my painting, unless I am doing something large like a dragon. Wow, if I was going to type up my own post, it would be almost exactly those words. Obviously I'm missing something regarding the Series 7 00. Why such a small brush?
