First you see the dry brush and how few hairs it has!
Next you see its size next to a Sharpie pen.
Then you see it on my palette and that is what I'm going to
tell you about.
To properly use this brush, you have to spread out a smear
of slightly thinned paint (the longest smear on my palette
in this photo). Flatten the smear with your palette knife so
that it is easy to pick up on the brush. Then hold the brush
so that it is practically parallel with the palette surface and
twirl it so as to get it all evenly covered with paint.
I use this brush for jobs such as painting whiskers on my
cat paintings!
