Well I've gone as far as I can with GIMP (and it isn't much).
I have a background I'd like to use for some maps but I can't get the edge to look like it's ripped/tattered/burnt (old parchment feel).
I found a great texture to use but with out the distressed edges it just doen't look right.
Here is the inspiration image (also a great map!) that has the edge effects i really like.
I’d really appreciate any help or tips on how to use GIMP to reproduce the distress effects.
