I have a new project in my pitch pot. A hand, in the "fear not" mudra.
The lines are also places where the metal is work hardened, so there are "channels" of softer metal where I can punch up a third dimension when I begin the repoussee.
I used a planishing tool to push back the metal around the hand, thinking to harden that area as well. Ordinarily, that wouldn't be done, but I am also experimenting here with the possibility of pure chasing, that is, working only the front of the piece. That requires good liner work, so I think at this point I am getting closer, but I do have farther to go to reach that goal. A lot of traditional chasing is worked just that way, front only.
It's a tricky mental shift from a flat drawing to dimension, adding relief to the concept, which actually will make the image change proportions, I think, getting narrower, or at least that's the plan.
After repoussee, I will anneal and clean the workpiece, fill the back with pitch, remount, and refine, using liners, planishers, and matte tools to add texture.
Stay tuned, and see how it goes!
