For my regular paintings I use Silver Black Velvet brushes. For wetting the background I use a flat 1.5″ inch wash brush (Renesans). For details I use spotter brushes (Rosemary&Co series 307). For shorter thin lines I use designers brushes (Spectre Gold size 2 and 4). For longer thin lines I use riggers by Cotman. Finally, I also have scrubber brushes for lifting out (various brands, I most often use a Galeria brush, size 4 by Winsor&Newton).
