This is what I use to watercolor :), I learned this technique from the staff of Carousel Rubber stamp store and am I glad I did learn it :)! I use the "Crayola markers", I draw on a piece of plastic of the color I want to paint with...then I use a small paint brush and a little bit of water. I run the paint brush across the ink on the plastic so it will pick up the ink, next I paint the stamped image. It is easy, it is cheaper than using actual watercolors, and it is sort of a fun twist to watercolor painting :D! Give it a try and let me know how it works for you :)!
