Here's something a bit different. It's a GIMP/Scribus crossover tutorial that combines a whole load of different techniques to make some "spooky" text. It's not for beginners as it doesn't lead you by the hand at every step, but people who have been following my other tutorials shouldn't have any real problems with it. I hope you like it.
