Pony King said:I'd guess at the coarse fabric in the first picture and the dirty paper in the second is what makes it look "western-y". Also looks much better than most of the stuff people try to make.
edit: If it's supposed to look more modern you'll probably have to look for more modern equivalents of the elements that you have in your picture. I can't remember seeing fabric that coarse, ever.
How can you go through life never seeing hessian?
