I'm definitly not a designer like you guys. I'm a
technician.
I love the fedora logo and I thought i can laser the logo on little stainless
steel plates.
A thought - I don't know what model laser machine you have, but the ones
I've seen do both engraving and cutting. Could you engrave the
"infinity" part and cut out the "f-cross" part? That would keep the
aspect ratio intact.
Another technique I've seen done involves creating slits for shading -
the distance between the slits can be less than the thickness of the
material, since the slits are so narrow, especially if the material is
as strong as stainless steel is.
