This started as copper plumbing pipe. I sliced off a section with the intention of making a riveted oval pendant–silly me. Shaping the slice into an oval wasn’t too difficult but drilling the hole for the rivet was a challenge and the side to side alignment was poor. I persisted and made the pendant but didn’t like the design or how it hung on the chain. So, back to the saw to slice the slice. I kept the side with the fewest divots from the drill. It hangs much better and still has some interesting curves.
