Does anyone out there know how to print double sided on 3x5 index cards on Pages? I set it to the 3x5 index card setting, but it won't let me print it. Also (better yet) does anyone know an app or whatever that is a flash card maker that you can print on index cards with? I have found ones that will print on regular size paper, but I would really like to print on actual index cards. Any help is greatly appreciated!
