Artist Note.
On yesterday's post I showed a video on how I use the fan brush
for foliage. The link I provided did not work so I am 
showing it again today.
Thank you to Lauren Nelson for sending me a corrected link.
I have never even met Lauren, but she has generously 
helped me with computer issues before.
Yesterday's post was on using oil paints but I have been asked 
if the same technique
works with watercolor or acrylic paints.
 Absolutely!
Above is a foreground base on which to 
develop texture or grasses.
I used watercolor and fan brush in same technique
as on the video  Naturally, the difference between the video 
and using watercolor would be starting lighter
and gradually adding the darker colors.

I start with my transparent darks first...
using the brush like a chisel
See short video below after reading.
Then I add the opaque colors using the same technique.
If you try it, then remember to leave some
of the darker areas showing. After the demo, I noticed many
of the artists were not using their arm or holding their brush
at end of the handle - they were controlling too
much by holding their bush in the middle, and being very careful.
Unfortunately, this results in a very uniform stroke.
So listen to the sound of the brush against the canvas
in the video and you can tell I whack at it.
I have found it gives a more 
natural appearance to build on.
Practice on a piece of canvas and remember you can
wash it off and keep starting again.  You will end up with a
canvas you can still use with a wonderful neutral base.
Take notes of the different effects you like so you can
repeat them
