Last night I was looking for something quick to work on. I had bought this set of 8 flair markers from Paper Mate. Their water base markers, so I thought I'd see what I could create with the set.
I basically just worked with patterns around the page until I got something I liked. Then I went in with a water color brush damped with clear water. When I applied the brush to the page the colors just exploded into soft pastel colors. You should give it a try and see what you can come up with.
