I've discovered a lot of stuff over the past year, but some still remains a mystery. I've taken to desining logos and tshirts whether for myself or other people, and Have been wanting to experiment with adding scratches, etc... to images to make it seem more worn (like the design pictured below) I've looked but I can't really figure out how to do it, mostly because I don't know how to word what it is what I want to do. Any help on this front would be greatly appreciated. Thanks
