@Drea I’ve actually done this before (very crudely). I was in a Mask and Armor making class and this was my simple armor project. I originally wanted to just laser engrave the bracers, but the laser machines are pretty new at our university and no one has really tried working with leather yet - ergo the setting were way off.
Basically the power was so low or the laser was unfocused so that it just burned a light tracing of the pattern onto the leather. I then went in with a swivel knife and tooled over the main veins of the feathers and some of the other lines for depth.
You can tell if you look at the picture that the engraved lines are fainter and are only super visible in the light, but that ended up being an effect that I liked. The outer edge of the braces also did not cut out, so the curving and shaping is something I engineered to make it look like they burned and curled.
I’m really looking forward to having a machine that I can try this kind of stuff with (and that is actually user-friendly!)
I hope that helped!
