Just trying something out. I took an MDF circle and spray-painted it with Rustoleum Paint+Primer to give it kind of a gun-metal look. I taped it up, and had my GF drill the center hole and engrave the flourish. I left the tape on after cutting and gave the engraved portion a coat of metallic spray paint.
I would consider this a rough draft, but I like the effect. Thought I’d share.
