Hello all! I decided to join this forum because I want to make my own bridle and breast collar. Problem is, I don't know have any idea where to start. I've been perusing through articles online and have a list of things I'm probably going to need.  
Strip and strap cutter 
Stitch marker 
Awl 
Harness needles 
Leather punch 
Edge trimmer 
Leather dye 
Gum tragacanth (not sure what this does or if I even need it?) 
Finish coat (not sure what to use for this, suggestions?) 
Leather (What kind?? I heard 8-9 oz. and up to 13 oz. I plan on tooling it.. Heard veg tan but not sure.) 
Buckles/conchos 
Anything else I might need? 
I'm going to Tandy Leather and getting a bunch of supplies, including a book on how to do this but wanted some tips first.  
ANY input is greatly appreciated!
