Someone (you know who you are) asked what I put in my watercolor journal. Watercolors, of course. :) Here's one I did this morning of Alexandra Keller.
One recycling/art trick -- I use old egg cartons as my water containers now when I paint. I get twelve separate little pools of clear water to use before I have to dump and refull, and I don't pollute my brush with a different color every time I change shades.
