Monk. It was a factory milgrain half round band the client brought in. I just did the engraving.
Basically I cut outlines of the mountain skyline. Then removed/relieved the area that was the sky. To do this I cut down with a square graver. Then came in with a 37 flat and smoothed it all out while maintaining the contour of the half round. Stippled the relieved area with a carbide stipple point. Lastly recut the skyline with a highly polished carbide 120 to add flash and better define the mountains.
