Hi, does anyone know the least expensive way we can make our save the date cards? Any ideas on a program to use so we can make the template for our card ourselves? We are thinking after we make the template to go somewhere and have them printed out, any ideas on where? Also if we do a postcard version, should we put it in an envelope so it doesn't get ruined or lost in the receiver’s pile of advertising mail? Or is it okay to send it without an envelope? Your help is very much needed and appreciated. Thanks!
