My process was as follows:
I first took a pair of scissors and made a cut at the bottom, then I carefully just torn up the coat until 8 got to the desired length. I varied both the distance between and length of the tears. I then went back with scissors and made some cuts along where I torn the coat so they wouldn't all be to linear.. next I took a wire brush and raked along th3 edges of th3 tears to make look even more torn up. Once I was happy with that I got some beeswax I had for when making wooden bowls and cutting boards, etc and rubbed that in to some of the tears and edges which help give it that weathered stringy look you see in th3 show when he's ou5 walking through the waste land. Lastly I go5 out some reference images and my leather paints and using a sponge created all those tan, yellow patches and streaks since on the prop coat ... that was itThanks, that helps… I’ll let you know how it goes!
