Forming it is used a lot and I've done that with a couple bibs but I live in Tx and we get a little hot and I have seen the bib start to curl at the edges if it isn't taken care of properly ( How many people actually will do what we tell em about conditioning it O.o LoL )but I think forming would still probably work with a thicker piece like a 5/6 or 6/7 oz. I used a lighter leather 3/4 so I used a piece of Kydex formed to the fender (which is why you see a couple ripples, still learning to work with that stuff) and then glued (DAP Weldwood) my top and back to that then braided it. It's hard to see but that piece is actually laying completely curved to my fender. Hope that helps explain it a bit better. For your drawing ... Hell I can't draw for crap either just try my best and practice, practice, practice
