Inspired by Roben-Marie Smith's idea, as I often am, I chose a Gelli print I did a while back, one of those prints that have lovely colours and textures, but not enough shape to finish in a frame on a wall (I have a lot of those). I cut out my initials in paper. I applied black paint to my Gelli plate, and placed my initials on it, in reverse! I had to think about that one, but a quick review of GelliArts' blog helped to clarify this for me. I then applied my old print over the plage and pulled this lovely print.
A little bit of enhancement with white markers, and I called it done.
