I thought I'd see how the newest Rogue Redhead Design stamps, Beach Babes, looked stamped on my crayon glassine paper, and I really liked the effect! I melted crayons in the blues and greens family onto the glassine and achieved a really nice watery texture. The boat image was a perfect fit. I also found that I could color in the sail and add highlights with a white gel pen.
Here is the same idea with the heron stamp, again with the white highlights. Check out the RRD blog for many more ideas using their newest stamp set.
