I just finished a costume belt for Luke from ROTJ. I used reference pics from museum replicas. I cant remember where I read it but I had read that the buckle was originally modified from a buckle blank from Tandy leather. So thats what I used. I made the buckle solid black so that someone who wanted to could distress it themselves or leave it stock. I made my own pouch and saber clip. I began by hand dying the belt dark brown and then put a black finish over that so the belt would more closely resmeble the belt from museum replicas.
