Classy looking sign. I like the small diamond near the bottom. Sometimes the small touches really add to a design. And using the rivnut approach is a great idea.
I have a rivnut gun. I haven’t used it in a year or so and never thought about using it to make multilayered signs. That could really get fun.
I did design a basic Kubota Tractor sign yesterday, but not real happy with it. Kubota has their own font with cutouts in the letters. Not my idea.
Putting an oval shaped logo on a round sign,… Only did it that way to try to save material. Appearance not so good IMO.
