If you have a cut and paste program on your computer, you can take a picture of the sett (There are a lot on the web). You can start cropping and then paste over and over. You can basically see what every different pleating scheme will look like (Keep in mind that pleat width may hinder some styles of pleating). You can also invent your own fashion pleating (I'm really liking this idea more and more) using this method.
