It’s one of those mornings with unexpected time to play around in the studio, and this is a small but useful discovery. I have some little wooden dominoes that I planned to use for closures on the journals and covers. I turned one over, sanded off some of the black finish, drilled some holes with an awl, and applied a paste of copper powder mixed with neutral shoe polish. It really came out well, much better than the photo (which was taken in a hurry on my iPhone). I think this has possibilities.
