There probably isn't that many Paint Shop Pro tutorials.

There might be one or two there, if not you can just browse the Adobe Photoshop tutorials, there are like fifty grunge signatures tutorials on just the front page of that place. In Photoshop most people feather the edges of an image to make it fade into the background (the background usually being some generic random grunge brushing), I've got no idea how to do that in Paint Shop Pro.
