There was one thing I had to learn first... I wanted to teach myself how to make a pin back. To be honest those 3 piece pin backs (hinge, pin, and clasp) are tiny and fiddly to work with. I have been watching YouTube videos and I even bought a book and I even bought some lapel pins with catches to try too.
I started at 930 am - anneal, pickle, wash, press, press, repeat. Then stamp, saw, file/sand, cut wire, solder, pickle, bend pin back into shape, polish and by 4pm I had one complete pin and put it on my hat. The second pin will be finished tomorrow when I will form the pin back and then the entire thing will be polished.
