I am a firefighter and looking to get into leather working. On every fire helmet is a leather front piece that serves as a form of identification while wearing the helmet. This is called a shield or front.
I have never done any leather working before but I would like to try to make a shield. I have attached a picture but in case you can't tell, the middle square (called an insert) has sunken or recessed numbers. The shields consist of 3 layers. A black front layer, a white or red middle layer, and another black layer for the backing.
I was wondering what kind of leather, as well as what tools I need to complete this job; or where do I find colored leather, etc. Any help is greatly appreciated.
