Here's my second fake card tutorial, this time for GIMP. It's more accurate than my old PowerPoint tutorial, but a few things are still off. Great for beginners, though. I tried to make it user-friendly. You can download it here. You'll need PowerPoint or PowerPoint Slideshow Viewer in order to read it.
Some people have found it difficult to locate the download on the linked page. It's towards the bottom of the page.
