Wow am I glad this thread is fairly recent! Been looking all over for some decent weathering tutorials and its coming up a bit scarce.
Im currently working on the Dovakiin from Skyrim pics

Being an old Warhammer player weathering the metal isnt an issue but im having trouble thinking of a way to do the leather.
Im using Faux leather,
this is the exact stuff I bought in Brown. I have double sided it and stitched along the seams with a lighter brown leather thonging and added the studs. So far I have only completed the leg guards but to be prepared in unsure on how to weather them and when I do it the upper body parts too. Generally want to make it look worn in and more natural.
