I found this useful tutorial recently that helped me create distressed looking type;

I would create each storyboard frame as a separate page in Indesign with a black border inside the page boundary.

When you want to print them, export the document as a pdf, open the pdf and print with ‘Multiple pages per sheet’ selected from the ‘Page Scaling’ dropdown menu.

Alternatively, you can print from Indesign and select Print thumbnails from the ‘Setup’ tab from the print dialogue window.
