This is simple rose made from 5 pieces of 1.5mm thick stainless steel.
Cutting can be done with the angle grinder, or rotary tool like i did.
For shaping i used ball head hammer. Parts are soldered together with silver and flux.
Step 1: Templates
Here's the templates for cutting. Not perfect ones, because some of the shape is free formed.
But, those are somewhat good start.
First video shows the cutting and shaping process.
Best result comes with multiple smooth hits, instead of couple "big ones"
Second video shows the soldering and smoothening process.
I removed the hammer marks with the rotary tool, using tungsten carbide cutters and sanding disks.
