I have been obsessed with leather tool bags that mimic the old doctor's bag look. So, I bought some leather and have produced some prototypes.
The style of these bags are great. The toughest part was getting the spacing for all of the rivets. If using copper rivets, in particular, I need to have all of the rivets set before gluing the bag together. So there cannot be post gluing rivet setting (except the top flap).
When I firts made the bag, I thought it would be a great chance to use button studs. I might reserve the button studs if I make the bag out of a stiffer leather.
