[Gimp-user] Creating brushes

[Rem P Roberti]

Hi Everyone...

I'm new to the list, and pretty new to the Gimp.  As a photographer I'm 
still using Photoshop
as my primary tool, because I need to be able to work on 16 bit images.  
I understand that
that eventually the Gimp will have 16 bit processing incorporated into 
the program. 
That being said, I do use the Gimp for some of my jpg files, and I am 
wondering if there is a
way to create larger soft brushes.  I often use a large soft brush for a 
number of things in
Photoshop (clone stamp, vignetting, various mask work) and the largest 
soft brush that I can
find in the Gimp is much too small.  Is there a work-around for this?

TIA...
