I was tired about I can't find any good quality emblem from the Brotherhood of Steel. So I decided to redraw it from the base. After I started there were two ways, first the "new one" and the rusty version, so finally there are two versions of it.
And the rusty: https://www.spreadshirt.com/brotherhood+of+steel-A5a7b1c50f6c60d1c0c3c29fe
At the few next images you can see how I made the graphics, what was the process to create the design.
