I made a tutorial for borders in photoshop, I'm pretty sure this would translate easily to GIMP. This is my first tut of any kind, so expect it to suck. [img width=240 height=800]http://i214.photobucket.com/albums/cc201/weapwnsmaster/Untitled-3.png[/img]
um.. I find that making a new layer as the top layer, and then filling it up, then putting the fill to 0% and inner stroke it with 2px. Its probably more easy to edit if needed.
